GENERAL INFORMATION The Bullet Probe features a one inch stainless steel probe that is designed for use with electronic controllers in commercial heating and cooling building management systems. It is available with multiple thermistor or RTD options. The bullet style sensor monitors air temperatures and should not be fully submerged in water. For optimal temperature measurement, follow these tips: • Do not install on external walls. • Avoid air registers, diusers, vents, and windows. • Eliminate and seal all wall and conduit penetrations. Air migration from wall cavities may alter temperature readings. • Do not install near heat sources. eg: lamps, radiators, direct sunlight, copiers, chimney walls, walls concealing hot-water pipes. MOUNTING INSTRUCTIONS Bullet Probe sensors may be mounted using a 1/4” mounting clip (ACI Item #108169) on walls or with cable ties along pipes. ACI’s Pipe mount Series is recommend for pipes from ½” (12.7mm) to 1” (25.4mm). The Bullet Probe may still be used, but the Pipe Mount has small curvature on the bottom that is designed to increase the surface area and improve the thermal conductivity between the pipe and the sensor. BULLET PROBE (-BP) ASSEMBLY ON WALL Take care when mounting. Check local code for mounting height requirements. The sensor should be mounted in an area where air circulation is well mixed and not blocked by obstructions. To x the BP on a wall, ACI recommends a height of 48-60” (1.2-1.5 m) o the ground and at least 1.5’ (0.5 m) from the adjacent wall. Slide the sensor probe through the mounting clip - see FIGURE 3 (p. 2). Drill a 1/4” screw through the socket and tighten to the wall. 1.00” (25.40 mm) 23.00” (584.20 mm) 0.65” (16.51 mm) 0.25” (6.35 mm) 0.25” (6.35 mm) FIGURE 2: PIPE MOUNT (-PM) DIMENSIONS TOP VIEW 0.31” (7.87 mm) 2.00” (50.80 mm) 1.10” (27.94 mm) 0.38” (9.53 mm)Automation Components, Inc. 2305 Pleasant View Road | Middleton, WI 53562 Phone: 1-888-967-5224 | Website: workaci.com Page 2 Version: 2.0 I0000815 FIGURE 4: BULLET PROBE (-BP) ASSEMBLY FIGURE 3: BULLET PROBE FIGURE 5: PIPE MOUNT (-PM) ASSEMBLY BULLET PROBE 1/4” MOUNTING CLIP PIPE MOUNTING For best accuracy and increased thermal conduc- tion between the pipe and the sensor, ACI recommends to clean the pipe with an emery cloth or le, before applying thermal grease. Be sure to insulate the probe (from the eects of the ambient air) after tightly fastening to the pipe. BULLET PROBE (-BP) ASSEMBLY ON PIPE To x the BP sensor along a pipe, use cable ties to mount the sensor probe and wires on the pipe - see Figure 4 (middle). PIPE MOUNT (-PM) ASSEMBLY ON PIPE For mounting along a small pipe with maximum 1” (25.4 mm) diameter, align the contoured PM sensor to the pipe and fasten with cable ties - see FIGURE 5 (below). WIRING INSTRUCTIONS ACI recommends 16 to 26 AWG twisted pair wires or shielded cables for all sensors. Signal wiring must be run separate from low and high voltage wires (24/120/230 VAC). All ACI thermistors and RTD temperature sensors are both non-polarity and non-position sensitive. All thermistor type units are supplied with (2) ying lead wires, and all RTD’s are supplied with (2) or (3) ying lead wires – see FIGURE 6 (right). The number of wires needed depends on the application. Connect thermistor/RTD wire leads to controller analog input wires using wire nuts, terminal blocks, or crimp style connectors. All wiring must comply with all local and National Electric Codes.

W.E.E.E. DIRECTIVE At the end of their useful life the packaging and product should be disposed of via a suitable recycling centre. Do not dispose of with household waste. Do not burn. TROUBLESHOOTING PROBLEM Sensor reading is incorrect Sensor reads infinity/very high resistance Sensor reads low resistance Erratic readings SOLUTION(S) •Verify sensor wiring to controller is not damaged and has continuity. • Verify sensor or wires are not shorted together. • Verify controller is setup for correct sensor curve. •Disconnect wires from sensor terminal block, tighten terminal block screws down, and take a resistance (ohm) reading with a multimeter. • Compare the resistance reading to the Temperature Vs Resistance Curves online: http://www.workaci.com/content/thermistor-curves-0 • Verify proper mounting location to conrm no external factors are aecting reading. • Sensor or wires are open. • Sensor or wires are shorted together. •Condensation on PCB board • Bad wire connections.

Connecting both ends of the shield to ground may cause a ground loop. When removing the shield from the sensor end, make sure to properly trim the shield to prevent any chance of shorting. Note: If the controller requires a (2) wire input for a RTD, connect the (2) common wires(same color) together. If the controller requires (3) wires, use (3) individual wires.PRODUCT SPECIFICATIONS Automation Components, Inc. 2305 Pleasant View Road | Middleton, WI 53562 Phone: 1-888-967-5224 | Website: workaci.com Page 4 Version: 2.0 I0000815 -40 to 150ºC (-40 to 302ºF) -40 to 85ºC (-40 to 185ºF) A/1.8K: 1.8 K nominal (Red/Yellow) A/2252: 2.252 K nominal (White/Red) A/3K: 3 K nominal (White/Brown) A/5K: 5 K nominal (Red/Gray) A/AN (Type III): 10 K nominal (White/White) A/AN-BC: 5.238 K nominal (White/Yellow) A/1.8K Series: +/- 0.5 °C @ 25 °C (77 °F) and (+/-1.0 °C) (+/-1.8 °F) -40 to 200 ºC (-40 to 392 ºF) -40 to 85ºC (-40 to 185ºF) A/100: 100 nominal +/- 0.06% Class A (Tolerance Formula: +/- °C = (0.15 °C + (0.002 * |t|)) where |t| is the absolute value of Temperature above or below 0 °C in °C) @ -40 °C (-40 °F): +/- 0.23°C (+/- 0.414 °F) @ 0 °C (32 °F): +/- 0.15°C (+/- 0.27 °F) -40 to 121 ºC (-40 to 250 ºF) -40 to 85 ºC (-40 to 185 ºF) 1 K nominal (Red/Red) @ -40 °C (-40 °F): +/- 1.52 °C (+/- 2.73 °F) @ 0 °C (32 °F): +/- 0.4 °C (+/- 0.72 °F) @ 21.1 °C (70 °F): +/- 0.17 °C (+/- 0.34 °F) -40 to 121 ºC (-40 to 250 ºF) -40 to 85 ºC (-40 to 185 ºF) 1 K nominal (Orange/Yellow) +/- 1% One 10 to 95% RH, non-condensing 304 Stainless Steel 22 AWG (0.65 mm) A/CP (Type II): 10 K nominal (White/Green) A/CSI: 10 K nominal (Green/Yellow) A/10KS: 10 K nominal (White/Blue) A/10K-E1: 10 K nominal (Orange/Gray) A/20K: 20 K nominal (Brown/Blue) A/100KS: 100 K nominal (Black/Yellow) A/10K-E1 Series: +/- 0.3 °C (+/- 0.54 °F) All Else: +/- 0.2 °C (+/- 0.36 °F) A/1K: 1 K nominal @ 200 °C 392 °F): +/- 0.55 °C (+/- 0.99 °F) @ 54.4 °C (130 °F): +/- 0.56 °C (+/- 1.00 °F) @121 °C (250 °F): +/- 1.25 °C (+/- 2.25 °F) SENSOR NON-SPECIFIC INFORMATION Number Sensing Points: Operating Humidity Range: Plate Material: Wire Size THERMISTOR Operating Temperature Range: Storage Temperature Range: Sensor Output @ 25 °C (77 °F): (Lead Wire Colors) *Does not include CL2P Accuracy @ 0-70 °C (32 - 158 °F): PLATINUM Operating Temperature Range: Storage Temperature Range: Sensor Output @ 0 °C (32 °F): Accuracy @ 0 °C (32 °F): NICKEL Operating Temperature Range: Storage Temperature Range: Sensor Output @ 21.1 °C (70 °F): Accuracy: BALCO Operating Temperature Range: Storage Temperature Range: Sensor Output @ 21.1 °C (70 °F): Accuracy @ 21.1 °C (70 °F):Next >
