Product Description

The Explosion Proof Pressure Switch is designed to monitor vacuum or negative pressure and provide a discrete electrical switching signal when the selected set point is reached. Changes in process vacuum act on the internal sensing element, which operates the electrical contact for use in alarms, equipment sequencing, pump control or safety interlocking.

Its robust explosion-protected enclosure is intended for industrial installations where reliable switching and environmental protection are required. The adjustable set point allows the switch to be matched to the operating condition, while the mechanical switching principle provides a simple and dependable interface with control panels, relays and shutdown circuits.

 

Typical Applications

- Vacuum pump start/stop control
- Low-vacuum or loss-of-vacuum alarms
- Suction-line and vacuum-system monitoring
- Filter, packaging and material-handling equipment
- Process equipment and safety-interlock systems in suitable hazardous areas

 

Key Benefits

- Consistent point switching at an adjustable vacuum set point
- Direct electrical contact for alarm and automatic-control functions
- Rugged enclosure for demanding industrial environments
- Suitable for equipment protection and process interlocking
- Straightforward installation and set-point adjustment

The selected pressure range, electrical rating, process connection, wetted materials and hazardous-area certification must be confirmed for the intended installation.
