(1) 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.
(2) 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 at Senva.com (see QR code on left) . Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated.
(3) These gases my be detected by the sensor but sensitivity curves are not available at this time.
(4) High altitudes will not cause the sensor to not operate, but will affect accuracy. To maintain accuracy spec, a field calibration is recommended.
