One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended. 15-30VDC/24VAC power supply voltage required for 10 volt output.
R134A sensor is factory calibrated to R134A gas but may be used as a general purpose refrigerant sensor. Sensitivity to some other gases can be found here . Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated.
These gases my be detected by the sensor but sensitivity curves are not available at this time.
