Skip to the content The Comptus A70H Series air temperature and humidity sensors, humidity and pressure transmitters provide analog output signals proportional to the condition (s) being monitored. These temperature and humidity sensors, including the relative humidity sensor, are used in conjunction with electronic data collection systems or for input to control systems. They are readily combined with meter relays to provide custom controls. Units are available with either 4-20mA out RS485 outputs. They are powered by 12-24 VDC.
The A70-T is a rugged 1K ohm platinum RTD temperature and relative humidity sensor designed for use in demanding environments. It is well suited to installations in industrial facilities and power plants requiring pressure humidity sensor automation.
The devices are available as single or combined parameter sensors, and have several radiation shield options.
Many types of industries use outdoor compressed air humidity sensors, humidity sensors for industrial applications, and temperature pressure sensors to improve facility response to outdoor environmental conditions. The sensors are designed with robust capabilities, providing stable and accurate results. This includes the integration of high temp humidity sensors and temperature & humidity transmitters, ensuring precision in monitoring environmental factors.
