Safety pressure monitoring, confirmation of accumulator bleed off for guard access preconditions, back pressure detection and process control.
Safety pressure monitors have been design 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 15psi 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.
Max Pressure: 340 Bar
Switch Contacts: 1 x Normally Closed (Safety) & 1 Normally Open
Fixed Set Point: 4 psi on depressurisation, 15 to 20 pressurisation Normally Closed contact change of state
