A70-T Air Temperature Transmitter

The Comptus A70-T Air Temperature Transmitter provides an analog signal proportional to air temperature. Standard signal formats include 4-­‐20 mA, 0-­‐1 VDC & 0-­‐1mA. A nickel wire resistance temperature device (RTD) is used to detect temperature. A radiation shield is included to reduce the effects of exposure to direct sunlight. The A70-T is readily combined with meter relays to provide custom controls.

Systems are available with outputs of 0-­‐1 mA, 0-­‐1 V or 4-­‐20 mA. All systems may be powered from either
120 VAC, 230 VAC, 12 or 24 VDC.


The instruments are available in a variety of packages including steel JIC boxes meeting NEMA 12 standards, weatherproof fiberglass enclosures meeting NEMA 4X, IP66 and IEC 529 standards and track mounted versions. NEMA 12 enclosures provide protection from dust for indoor applications. NEMA 4X enclosures may be used indoors or outdoors. They provide protection from corrosion, wind blown dust and rain and are undamaged by ice. Track mounted versions are intended for mounting inside an enclosure provided by the user. Where required, electrical connection to the sensor is via terminal block. A barrier strip is provided for connection to operating power.

Each Comptus air temperature transmitter is provided with a detailed instruction manual. Comptus air temperature transmitters are manufactured in the USA.
