BA/592 (2 Wire) sensors

1. Make sure a 10K 0.1% resistor is installed
between the sensor output (Black wire) and
Ground.

2. Connect the sensor output (Black wire) to the
analog input (A.I.).

3.Connect Power (+5 to +30 VDC) to the power
lead (Red wire).

Offsetting

All BA/592 sensors will have the following information provided on a label:

BA/592-SP/AP-K

Therm Reading_______

The actual temperature reading
according to a thermometer that is
certified traceable to recognized
standards by the National Institute of

Sensor Reading ______

The temperature reading according to
the AD592 sensor, using the output in
either mA or mV and converting the
output to a Fahrenheit temperature.

Offset_______

The difference between the
Thermometer Reading and the
Sensor Reading

Standards and Technology (NIST).

To correct the Sensor Reading, simply add the offset value to the sensor reading so that it equals the thermometer
reading.

e.g. Therm Reading 74.6 Sensor Reading 73.0 Offset +1.6

Correction: Add (+1.6) °F to the sensor for an accurate reading: 73 + 1.6 = 74.6°F

e.g. Therm Reading 75.4 Sensor Reading 77.2 Offset -1.8

Correction: Add (-1.6) °F to the sensor for an accurate reading: 77.2 + (-1.8) = 75.4°F

Trouble Shooting

If the unit you installed does not respond properly, please
go through the following steps:

1. Set your meter to the mV setting.

2. With the unit configured according to the diagram
below (note 10K ohm 0.1% resistor required with
592 sensor) apply the power and measure the
“Sensor out.”

3. Compare the voltage reading to the voltage
listed in the output table listed.

4. If the sensor reads significantly lower or 0,
then your sensor is shorted.

5. If the sensor reads significantly higher or OL
(overload) then the sensor is open.

6. If the sensor reads properly, verify that the
controller is operating correctly.
