Explosion-proof Ex-VCM and Ex-VNM FEMA pressure controls are designed for use with liquids and gases. These devices are characterized by the highest quality of workmanship, which translates into many years of reliable operation. The series consists of a dozen or so models of devices that differ in selected parameters.

Ex-VCM and Ex-VNM FEMA vacuum pressure switches detect the pressure difference to the atmospheric pressure. All data relating to the switching pressure ranges, and thus also to the scale divisions on the switching devices, is to be understood as the pressure difference between the atmospheric pressure present and the set switching pressure. The "zero" reference point on the scale of the device corresponds to the corresponding atmospheric pressure.
All models of pressure switches Ex-VCM and Ex-VNM FEMA are equipped with an internal thread G¼ and an external thread G½.
The maximum temperature of the medium at the pressure sensor must not exceed the permissible ambient temperature at the switching device. Higher medium temperatures are possible, provided that the above limits are met by additional measures. Protection class: Ex II 2G Ex de IIC T6 Gb, and Ex II 1 / 2D Ex ta / tb IIIC T80oC Da / Db.
