Pressure Difference Switches

Orion pressure difference switches are available in various ranges from 0.1 bar to 25 bar. In these switches, two opposing pressures are used to switch an electric circuit at a preset pressure difference. These switches find application mainly across filters in pressure lubricated systems, or to indicate flow/no flow by sensing pressure difference across an orifice. A choked filter or a pressure difference across the orifice will activate the switch and the resulting signal can be used to sound an alarm or light a lamp on control panels. The signal can also be used to switch off pumps or energize/de-energize other electrical circuits depending on the application. The switch can be used on a variety of working media like refrigerant gases, oil, air, water, steam, etc, by selecting appropriate wetted parts. The pressure ports for both the high and low side are I/4"BSP female. The electrical rating of the switch is 5 A, 250 V AC/O.2 A, 250 V DC. Orion pressure switches are also available in various other ranges from 15 mm wg to 400 bar.
