IX. Temperature Sensor
a. Temperature sensor specifications.
Output: 4-19mA
Range: -50° C to + 50° C
Accuracy: ±0.2° F or ±0.1° C
Operating Voltage: 10-36VDC
Current Draw: Same as sensor output
Warm Up Time: 5 seconds minimum
Operating Temperature: -50°C to +100°C
Size of Probe: ¾" diameter x 4 ½" long
Weight: ½ lb.
b. The sensor is a two-wire sensor using the red wire for power and the
black wire for the output signal. Warning: Always connect the
sensor with the power turned off.
c. Do not install the temperature sensor in direct sunlight.
d. To check the temperature sensor calibration you will need:
1 thermometer
3 containers of water
1 power supply
1 current meter
Connecting wires as necessary
Connect the sensor to the power supply and current meter in
the following way. Attach the black wire to the positive input of the
current meter. Connect the ground terminal of the power supply to the
ground of the current meter. Attach the red wire to the positive
terminal of the power supply. Warning: Always connect the sensor
with the power turned off.
See Appendix A for the temperature calibration worksheet.
