The RHT-DM Relative Humidity and Temperature Transmitter converts these two physical parameters into two industry standard, isolated, highly stable and interference free 4 to 20 milliamp signals.
The sensors are mounted on the probe tip (protected by a polypropylene filter cover) and are un-pluggable and washable. Both outputs are two wire transmitter loops, requiring a 24Vdc (nominal) supply in both loops. The same pair of wires that supply power to the circuitry then carry the signal to the measuring device. The two outputs would normally be used as inputs to PLCs, controllers, digital indicators, data loggers or SCADA or telemetry systems.
