ACI/WP Series

Product Description

The ACI/WP Series is a two-wire wet to wet differential pressure transducer. The ACI/WP is ideally suited for use with any harsh media, wet or dry, that is compatible with 316C series stainless steel. Some of the most common applications for the ACI/WP are:

            ·         Chiller and Boiler Systems
      ·         Pumps and Compressors
      ·         Environmental Control Systems
      ·         Level Monitoring
      ·         Refrigerant Systems

The ACI/WP may be powered with a 15 to 30 VDC supply voltage and outputs a linear 4 to 20 mA signal. To ensure an accurate linear analog output, the WP contains circuitry to provide signal conditioning, reverse polarity protection, and temperature compensation as an integral part of the device.

Built for remote installation, the ACI/WP is a rugged unit, housed in a splash proof, dust proof NEMA 4 stainless steel enclosure. Both of the input pressure ports use a 1/4” NPT Male fitting. Each unit is approximately 2.02” long x 1.875” tall x 0.75” in depth and weighs approximately 0.75 lbs. All connections are to be made to the 12” cable that is attached to the unit.

The ACI/WP pressure transducers are available in ranges from 0 to 15 psid all the way up to 0 to 500 psid. All units are accurate to +/- 0.25% of the full scale output.

All of the ACI/WP Series transducers have a 2 year warranty. Other spans and outputs may be available upon request. Snubbers are also available upon request. Contact ACI for more information regarding the ACI/WP.
