A70-HT Relative Humidity & Air Temperature

Comptus Humidity and Air Temperature Transmitter provide analog output signals proportional to relative humidity and air temperature. These units are used in conjunction with electronic data collection systems or for input to industrial control systems. They are readily combined with meter relays to provide custom controls.

Systems are available with outputs of 0-­‐1 V or 4-­‐20 mA. The A70-­‐HT is powered from 6 -­‐ 30 VDC.

Temperature is detected using a Permalloy RTD, conforming to IEC 751 Standards. Relative humidity is sensed by a thin-­‐film polymer capacitor sensor with excellent durability in harsh environments. The temperature & relative humidity sensors are protected by a hydrophilic membrane under a wire meshscreen.

Each Comptus relative humidity and air temperature sensor system is provided with a detailed instruction manual. Comptus relative humidity and air temperature sensors are manufactured in the USA.
