SENSAPHONE HUMIDITY TRANSMITTER • FGD-0052
Installation Instructions
The Sensaphone Humidity Transmitter sensor will allow you to monitor Humidity from 0-100% with any Sensaphone that will accept
a 4-20 Input signal. The FGD-0052 will require a 24VDC power supply to operate (Part No: FGD-0070) for any Sensaphone that does
not provide 24VDC output power.
Note on wiring: Use 22AWG shielded wiring for all connections (Sensaphone Part No. FGD-0010) and do not locate the device wires
in the same conduit with wiring used to supply inductive loads such as motors. Disconnect the power supply before making any con-
nections to prevent electrical shock or equipment damage. Make all connections in accordance with national and local codes.
