The detector differential pressure SRD-M1

The detector differential pressure designed for electric switch circuits when the set difference of two compared to the pressure of the air or non-aggressive gases.
The scope of the detector are the automation systems domain process and similar systems in metallurgy.

For protection against environmental influences detector available explosion-proof, has explosion-proof protection level "flameproof enclosure" according to GOST 22782. 6-81 and can suitable for use in hazardous areas of buildings and outdoor facilities may form explosive mixture of gases and vapors.The explosion protection:
