Pressure controllers and gauges

The Series A3 digital differential pressure controller is a microprocessor-based pressure controller for positive, negative and differential pressure as well as velocity and flow. The Series A3 differential pressure controller includes two 8A SPDT relays and an associated software package that allows full configuration of variables such as set points, dead band, engineering units and flow coefficients. The programming is done from a user-friendly menu on the LCD or uploaded using an Opti Link programming key. The LCD also displays the exact set points or other user-defined variables during normal operation. The menu structure can be customised by moving variables to different menu levels to accommodate many applications.

The Series S2000 differential pressure gauges are low-cost, diaphragm-operated, mechanical-pressure gauges. The S2000 gauge can be used in applications for measuring positive, negative or differential pressure with an accuracy of 2%. Standard applications include monitoring filter status, duct static pressure, room pressure, fan or blower pressure, paint booths, dust collectors and cabinet purging along with many others.
