It is ideal for mounting applications inside electronic circuit enclosures or existing thermostats. •The Remote Probe is a small Stainless Steel temperature sensor used for single point temperature measurement. It is ideal for bracket mounting for Chamber, Duct, Thermowell or L-bracket applications. It is available with Plenum-Rated, FEP-Jacketed or FEP-Jacketed Submersible Cable. Both sensors are available with a variety of thermistor or RTD sensing elements. The probe is available alone or with various enclosures. This instruction sheet is specific to the sensors and probes with the BAPI-Box Crossover Enclosure. For other enclosures, please refer to instruction sheet “20910_ins_ Remote_Sensor_Passive.pdf” which is available on the BAPI website or by contacting BAPI.

Overview and Identification Fig 2: Remote Probe Fig 1: Remote Sensor Mounting the Probe Fig 4: Remote Probe Strapping to Pipes MOUNTING THE PROBE TO A PIPE Step 1: Secure Sensor To Have Good Contact With Bare Pipe Step 2: Insulate Over The Sensor. Insulation should be installed a minimum of 4 pipe diameters on each side of the strap-on sensor. Example: ½” pipe x 4 = 2”. Insulation should be 2” on each side of the sensor wrapped all the way around the pipe.

Larger gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes. Do NOT run this device’s wiring in the same conduit as high or low voltage AC power wiring. BAPI’s tests show that inaccurate signal levels are possible when AC power wiring is present in the same conduit as the sensor wires.

A 1/8” inch pilot screw hole makes mounting easier through the tabs. Use the enclosure tabs to mark the pilot hole locations. The BAPI-Box Crossover enclosure has a hinged cover for easy termination and comes with an IP10 rating (or IP44 rating with a pierceable knockout plug installed in the open port). Notes: Use caulk or Teflon tape for your conduit entries to maintain the appropriate IP or NEMA rating for your application. Conduit entry for outdoor or wet applications should be from the bottom of the enclosure. Fig 5: Break-off Tab of a Flexible Probe Bracket (BA/FPB) USING THE BREAK-OFF TAB OF AN FPB A break-off tab on BAPI’s Flexible Probe Bracket (BA/FPB) may be used to mount the remote probes. The BA/FPB is made out of tough UL94V Nylon and limits heat/cold conduction to the probe from the surface.

The High position forces the “Sensor A Out” to a very hot reading and the Low position forces “Sensor A Out” to a very cold reading (see Table at right). TERMINATION OF UNITS WITH A TERMINAL STRIP OR TEST AND BALANCE SWITCH Possible Solutions: -Confirm the input is set up correctly in the front end software - Check wiring for proper termination & continuity. (shorted or open) - For units with a Test & Balance Switch, verify that it is in the center position. - Measure the physical temperature at the temperature sensor’s location using an accurate temperature standard. Disconnect the temperature sensor wires and measure the temperature sensor’s resistance across the sensor output pins with an ohmmeter. Compare the temperature sensor’s resistance to the appropriate temperature sensor table on the BAPI website. If the measured resistance is different from the temperature table by more than 5% call BAPI technical support.
