REED Contact Gauges

REED Contact GaugesIntroduction

The Druva REED contact gauges provide reliable, precise pressure indication for regulators and manifolds. Designed with durable stainless steel housing and a solid baffle wall, these gas pressure gauges ensure safety by allowing gas discharge via the blow-out back of the gauge in the event of an accident. The potential-free signal of the REED contact gauges can be processed by our own signal boxes of the type DGM-SK as well as by superordinate building management systems.

Potential-free indication ensures reliable pressure monitoring on both sides of gas regulators.
Stainless steel housing with a solid baffle wall meets S3 safety standards (EN 837-1).
Blow-out back for safe gas release in case of an accident.
Suitable for hazardous areas when operated in an intrinsically safe circuit as per EN 60079-11.
