Pressure Switches P88GSwitch Economical Pressure OVERVIEW The Whitman Controls P88G Economical Pressure switches are typically used in applications where reliable switch control supersedes accuracy of set point. These switches can be used in dry indoor applications or placed within an enclosure. Controlling on and off functions for fans and pumps where one may need a wide differential to prevent over-cycling is an ideal application use for the P88G. 23/8” Nom. • Consistent switch control • Set point options: Factory set, field adjustable, or a combination • Extensive operating temperature range...

The Whitman Controls P90 Severe Environment Pressure switches are built to operate in harsh conditions and are typically used in vehicle applications both off road and on. As these switches are NEMA 6 rated, they are weather proof and briefly submersible. Ideal use is on log skidders, tractors, handi-vans, cranes and numerous other applications where shock, vibration and weather are of primary concern. • Shock resistant up to 150G • Vibration durability of 10Hz to 2,000Hz @ 10G’s • Water resistant up to 1,000 PSIG high pressure spray • Cold Storage up to -67oF (-55oF) • NEMA 6 Rated: Weather-proof...

Pressure Switches P95 Environment Pressure Switch High Pressure Severe OVERVIEW The Whitman Controls P95 Severe Environment Pressure switches are built to operate in harsh conditions and are typically used in vehicle applications both off road and on. As these switches are NEMA 6 rated, they are weather proof and briefly submersible. Resiliency in high pressure conditions is the key differentiator relative to its P90 sister switch, with the ability to withstand hydraulic spikes to 4,000 psig. Ideal use is on log skidders, tractors, cranes and numerous other applications where pressure spikes,...

Pressure Switches P100G Environment Pressure Switch High Accuracy Low Pressure OVERVIEW The Whitman Controls P100G High Accuracy Low Pressure Environment Pressure switches are ideal in light pressure applications where precision of setpoint must be high and repeatability low. These switches are commonly used in natural gas well heads, natural gas generator sets, and air applications like forced draft blowers. The P100G can be used both in dry indoor applications or within an enclosure. • Highly accurate setpoints and repeatability • Set point options: Factory set, field adjustable, or a combination...
