Relative humidity transmitter 0 - 100 %rH, -10 ... +80 °C | RHV

screw-inthin-film2-wire

COMECO’s RHV probe is designed to replace the old RHS model for HVAC applications. Using thin-film sensor, whose capacitance varies proportionally to medium relative humidity, and a thin-film temperature sensor, the probe measures relative humidity and temperature of air and non-aggressive gases at atmospheric pressure, and transforms it into standard current or voltage output signal. The RHV transducer allows external control of the input/output conversion (RH or temperature) through a special programming input. Depending on the output wiring, 2 variants 2-wire and 3-wire are available, as both may have serial interface. The probe has a 4-pin M12 circular connector with IP65 mounted and can be optionally equipped with a stainless steel sintered filter for sensor protection. Thanks to its robust stainless steel case, flexible communication potential, and attractive price, the RHV transmitter can be widely used in HVAC and food industry control systems.
