A70-P Barometric Pressure Transmitter

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

Pressure Transmitters 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. Comptus NEMA 4X enclosures may be used indoors or outdoors and provides protection from corrosion, wind blown dust and rain and ice. Track mounted transmitter 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 barometric pressure transmitter is provided with a detailed instruction manual. Comptus barometric pressure transmitters are manufactured in the USA.

 

A70-P Barometric Pressure Transmitter

Use: General Monitoring

Barometric pressure is sensed by an integrated silicon absolute presure sensor with internal temperature compensation. The sensor is mounted to the signal conditioner board. A 3/16 inch diameter tube may be attached to the sensor to provide remote pressure sensing. The output of the sensor is scaled to provide the desired output signal. 
  
Systems are available with outputs of 0-1 mA, 0-1V or 4-20 mA. All systems may be powered from either 24 VAC,120 VAC, 230 VAC or 12-24 VDC.

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.
