These transducers provide a proportional analog signal based on the sensed pressure.The P599 Series Transducers feature environmentally protected electronics with stainless steel construction. The digitally compensated P599 Transducers are highly accurate over a broad temperature range, resisting the effects of wide ambient temperature swings, high humidity, condensation, and icing.The pressure port is machined from 304L stainless steel. No o-rings or organic materials are exposed to the pressure media, allowing for a leak-proof, all-metal, sealed pressure system. The P599 Series Transducers operate with any corrosive or non-corrosive refrigerants that are compatible with stainless steel (304L SS), including water condensate, carbon dioxide, glycol, most refrigerants (including ammonia), and many other compatible fluids and gases. The P599 Transducers also can be used with the following natural refrigerants: NH3 (ammonia) and CO2 (carbon dioxide) in accordance with hazardous location requirements. The P599 Series provides transducers in a variety of pressure ranges, covering most common refrigeration and air conditioning applications.Features and Benefits•Industrial Duty Design—Offers a sealed design that includes a snubber to dampen pressure pulsations and has no o-rings for reliable performance in the most harsh environments.•10 Million Plus Full Scale Pressure Cycle Rated Life Span—Provides life use with no degradation of accuracy or performance over the life of the transducer.•Approved for Today’s Refrigerants—Use with an extensive number of refrigerants, including HCFC, HFC, CO2, and ammonia.•Environmentally Protected Electronics—Provide high vibration tolerance and prevent ingress and egress that can occur through suction line icing and thawing.Figure 1: P599 Electronic Pressure TransducersP599 Series Electronic Pressure TransducersProduct/Technical BulletinCode No. LIT-12012446Part No. 24-7664-3264, Rev.

P599 Transducers provide several output signal options: 0.5 to 4.5 VDC ratiometric, 0 to 10VDC, and 4 to 20 mA. The 0 to 5 VDC and 1 to 5 VDC output signals are also available on non-standard, bulk order purchases. See Ordering Bulk Quantities of Non-Standard P599 Transducers for more information on non-standard models.Typical applications include:InstallationSee Mounting and Wiring for information on installing the P599 Series Electronic Pressure Transducers.MountingThe compact, lightweight P599 Transducer mounts directly to most refrigeration equipment pressure tap ports. IMPORTANT:The P599 Series Electronic Pressure Transducer is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the P599 Transducer could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the P599 Transducer.IMPORTANT : Le P599 Series Electronic Pressure Transducer est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du P599 Transducer risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du P599 Transducer.• HVAC and refrigeration applications• Heat pump• Chillers• Fan speed controls• Pumps and compressors• Agricultural applications• Industrial process controlRisk of Property Damage.Mount the pressure control separately from the electrical cabinet and seal all electrical piping to prevent ammonia from migrating to electrical components. Where there may be exposure to ammonia, use only ammonia-compatible control modules and pressure connections. System shutdown due to improper adjustment may cause property damage.Risque de dégâts matériels.Installer le régulateur de pression séparément de l'armoire électrique et étanchéifier tous les conduits électriques afin d'éviter que de l'ammoniac n'entre en contact avec des composants électriques. En cas d'exposition potentielle à de l'ammoniac, utiliser uniquement des modules de régulation et des raccords de pression compatibles avec la présence d'ammoniac.- L'arrêt du système en raison d'un réglage inapproprié risque de provoquer des dégâts matériels.P599 Series Electronic Pressure Transducers Product/Technical Bulletin3To mount the P599 Transducer:1.Hand thread the P599 Transducer to the pressure tap point.2.Tighten the connection using the provided wrench flats to avoid damaging the transducer. See Technical Specifications for recommended assembly torque values.3.Perform a leak test on the connection before putting the system into operation.WiringObserve the following guidelines when wiring the P599 Transducer:•Ensure wiring conforms to the regional, national, and local electrical codes and regulations.•Do not exceed the transducer's electrical ratings (Table8).•Do not extend the wiring harness leads more than 76m (250ft). Use 22 AWG stranded, twisted, 3-wire, shielded cable to extend wiring harness leads.•Do not run low-voltage cable in conduit or wiring troughs with high-voltage wires. •Ensure that the shielded cable is terminated according to code and the control’s instructions.Wiring in Hazardous LocationsP599 Transducers are cUL Recognized for use in ClassI, Division2 GroupsA, B, C, and D locations. Follow these additional guidelines when wiring or servicing a P599Transducer in a nonhazardous location. Checking Transducer OperationIMPORTANT:When installing the P599Transducers, observe all regulations governing the handling and containment of hazardous or regulated materials (refrigerants or lubricants).IMPORTANT:Locate pressure tap points on the top side of the refrigerant lines to reduce risk of equipment damage or malfunction caused by accumulation of oil, liquids, or sediment at the transducer-to-refrigeration port pressure connection.IMPORTANT:Avoid severe pressure pulsations on high-side pressure connections by positioning the transducer away from compressor discharge.Risk of Explosion or Fire.Do not disconnect the P599 Series Electronic Pressure Transducer while its circuit is energized, unless the area is known to be nonhazardous. Disconnecting the P599 Transducer in a hazardous area while its electrical circuit is energized may result in an explosion or fire, and may cause serious injury or death.Risque de explosion ou incendie.Ne pas déconnecter le P599 Series Electronic Pressure Transducer lorsque son circuit est sous tension, sauf s'il est avéré que la zone est non dangereuse. La déconnexion du P599 Transducer dans une zone dangereuse alors que son circuit électrique est sous tension risque d'entraîner une explosion ou un incendie et de provoquer des blessures graves, voire mortelles.IMPORTANT:The P599 Transducer is a precision sensing device and testing accuracy is typically beyond the capability of field diagnostic tools.P599 Series Electronic Pressure Transducers Product/Technical Bulletin4Before applying power, check all wiring connections. After applying power, operate controlled equipment under normal conditions and use a reliable set of pressure meters to verify that the transducer and the associated control are operating properly.0.5 to 4.5 VDC Ratiometric VersionsThe ratiometric versions of the P599 Transducer receive a constant 5 VDC input supply voltage and vary the output signal voltage, based on the sensed pressure. The output voltage varies from 10% to 90% of the supply voltage, providing a 0.5 to 4.5 VDC output signal.Note:The 0.5 to 4.5 VDC ratiometric transducers are rated for 5.0 ±0.25 VDC, Safety Extra-Low Voltage (SELV). Exceeding the supply voltage rating can damage the transducer and void any warranties.To verify that the transducer is working properly:1.With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable pressure meter. This value is the measured pressure (P).2.Determine the maximum (Pmax) and minimum (Pmin) pressure values for the transducer’s pressure range (Table1 and Table4).3.Measure the voltage between Supply wire (red) and Common wire (black). Use this value in Step3 as the measured supply voltage, Vs.4.Use the equation in Figure2 to determine the calculated output voltage for the ratiometric transducer.5.Using your multimeter, measure the DC voltage between the transducer output and common (-) pins. See Table9 for the pin out configuration. This is the measured output voltage.6.Compare the calculated output voltage (Step4) and the measured output voltage (Step5). If the measured output voltage differs greatly from the calculated output voltage, replace the transducer.Note:It is normal for the transducer reading to differ somewhat from pressure meter readings due to voltmeter and pressure meter tolerances or other factors.0 to 5 VDC, 1 to 5 VDC, and 0 to 10 VersionsTo verify that the transducer is working properly:1.With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable meter. This value is the measured pressure (P).2.Determine the maximum (Pmax) and minimum (Pmin) pressure values for the transducer’s pressure range (Table1 and Table4).3.Use the equation in Figure3 to determine the calculated output voltage for the 0 to 10 VDC transducers.4.Measure the voltage between the transducer output and common (-) pins. See Table9 for the pin out configuration. This is the measured output voltage.5.Compare the calculated output voltage (Step3) and the measured output voltage (Step4). If the measured output voltage differs greatly from the calculated output voltage, replace the transducer.Note:Under normal conditions, the transducer reading can differ somewhat from pressure meter readings due to voltmeter and pressure meter tolerances or other factors.Figure 2: Voltage Calculation for 0.5 to 4.5 VDC Ratiometric TransducersFigure 3: Voltage Calculation for Voltage Regulation TransducersP599 Series Electronic Pressure Transducers Product/Technical Bulletin54 to 20 mA VersionsTo verify that the P599 Transducer is working properly:1.With the transducer in place and the controlled system pressure stabilized, measure the pressure at the transducer with an accurate and reliable gauge. This is the measured pressure (P).2.Determine the maximum (Pmax) and minimum (Pmin) pressure values for the transducer’s pressure range (Table3 and Table6).3.Use the equation in Figure4 to determine the calculated output current for the 4to 20mA transducers.4.Measure the transducer output current. To measure the transducer output current: Disconnect the common (-) wire. Set your multimeter to milliamperes (mA). Then connect the multimeter’s red test-lead to the transducer output common (-) PIN wire and the multimeter’s black test-lead to the common (-) wire. The milliamperes (mA) reading on your multimeter is the measured output current. See Table9 for the pin out configuration.5.Compare the calculated output current (Step3) to the measured output current (Step4). If the current from measured output differs greatly from that in the calculated output, replace the transducer.Note:Under normal conditions, the transducer reading can differ somewhat from pressure meter readings due to multimeter and pressure gage tolerances or other factors.Repair InformationDo not attempt to repair or recalibrate the P599 Series Electronic Pressure Transducers.
