How does the control system know zero pressure is achieved following isolation?

 

 

Zero pressure monitoring provides a single or dual channel means to feedback the isolation status of a hazardous energy system.

 

 

Safety pressure monitors have been designed to interface into new or existing safety systems where residual pressure must be depleted. The monitors consist of a non-adjustable preset between 3 & 6 psi switchover on depressurization and 15 psi switchover on rising pressure.

 

 

 

The pressure monitor incorporates a two-pole positive driven plunger type switch, with positive opening contact pre-approved to category 4 safety applications. A single pressure monitor is suitable for category 2 applications when used in conjunction with another safety function or two independent units are suitable for pressure monitoring in category three or four applications.

Why Choose Zero Pressure Monitoring?

✅Detect Isolation Completion of Hazardous Fluid Power in systems up to Cat. 4

✅Robust design with Aluminium or Stainless Steel Housing

✅Positively driven switching contacts for maximum reliability

✅High pressure operation up to 340 Bar (34000KPa)
