Vaccum Switches are available in two basic categories based on ranges: Full vacuum range and Low vacuum range.

In any application when the Digital signal is required as soon as the process exceeds set vacuum limit set in the Vacuum Switch (either on rising side or on falling side) the Fixed Differential type Vacuum Switches are used.

In case of Vacuum control applications, Adjustable Differential type Vacuum Switches are used.

We have a wide range coverage from 100 to 760 mm Hg. All these switches are available in IP 54, IP 65, IP 66 and flameproof enclosures.

In case of Low Range Vaccum applications we offer Low Range DP Switches, where in the high pressure port has to be kept open and vacuum has to be connected to the Low Pressure port. The range covered is from 15 mm Wc up to 2500 mm Wc. http://www.nkinstruments.com/products/Vacuum-Switches/se-b0RNB-kePbILJdSB5GYA-tfOHlR1gXxT9aGXLEDE
