Compound Switches

Compound Switches

We manufacture a wide range of compound switches to meet the needs of any industrial application and operating environment. Each of our sensors is highly customizable with numerous pressure ranges, fittings, electrical connections, and wetted materials available for selection. The Whitman name was built on our pressure products over 45 years ago, and we pride ourselves on the quality and diversity of our offering. Contact our engineering team to discuss your custom project today and Whitman solutions we can design to meet your exact needs.

Compound Pressure Vacuum switches allow the end user to control an applications where positive and negative pressures exist. Two of our most reliable pressure switches can also be custom designed as compound pressure switches including both the P88 and P100. These units afford the end user a wide range of pressure and vacuum set points, and can be used across numerous media and applications. Much like all our products, these compound switches are field adjustable or factory-set, and come with a vast array of pressure and electrical connections.

  1. P88C - Economical Compound Switch

    P88C - Economical Compound Switch

    $45.00 $40.50

    Part # P88C

    The P88C Economical Compound switches are typically used in applications where reliable switch control supersedes accuracy of set point. These switches afford the end user the ability to operate in positive and negative pressure ranges. 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 P88.

    • Set Point Range: 1.5 to 500 PSIG Gauge and 6 to 28.0 InHg Vacuum
    • Max System Pressure: 600 PSIG
    • Temperature range: -31°F to + 185°F (-35°C to +85°C)
  2. P100C - Inches of Water Compound Switch

    P100C - Inches of Water Compound Switch

    $87.50 $78.75

    Part # P100C

    The P100C High Accuracy Compound Switches are ideal in applications where precision of setpoint must be high and repeatability low. The P100C is highly versatile with the ability to operate in positive and negative pressure environments. These switches can be used both in dry indoor applications or within an enclosure.

    • Set Point Range: Vacuum to 15.0 PSIG
    • Max System Pressure: 15 PSIG
    • Temperature range: -65°F to +190°F (-54°C to +88°C)
