5000 Series Differential Pressure Switch

Series 5000 Differential Pressure Switches provide reliable snap action switching in a miniature package while retaining dependability for critical applications.

Incorporating a highly flexible elastomeric diaphragm, the compact 5000 Series switches can be set from 2 inches water to 60 p.s.i.d. or higher for specified applications.

Units can be provided with either electrical connectors or electrical wire leads. Switches are available with either stainless steel or elastomeric diaphragms dependent upon pressure ranges, media or other requirements. Minimal switching hysteresis for setpoint accuracy.
