DRD series pressure sensors relays.

Sensors relays of pressure are intended for use in monitoring systems, managements and regulations of excessive pressure (pressure) and vakuummetrichesky pressure (draft) of gas burner devices, household heating installations and in technological pipeline systems for management of a stream of the natural, liquefied gas, air and other gaseous nonaggressive environments.

Example of designation: DRD-120ATU RB sensor relay 200020142.025-2000.
