Pressure Switches

Pressure Switch Manufacturer & Supplier

We are a pressure switch manufacturer producing a wide range of pressure, vacuum, and compound switches and sensors 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.

Pressure Switches

Whitman controls offers the most diverse selection of pressure switches in the industry. Our diverse line of switches are used across a wide range of applications including blowers, generator sets, off-road vehicles, compressors, wafer ovens, process equipment, flow control devices, pumps, wastewater, heating and cooling systems, and numerous other applications across industries. Our competitive advantage lies in our ability to custom engineer switch and sensor solutions that meet the exact needs of your application and media. Whitman has been working with large OEMs for over 40 years, and our longest running customers are those we have custom designed switch solutions for since our early years.

We offer low pressure units (up to 1,000 psig) and higher pressure units with proof pressures up to 6,000 psig and burst pressures up to 9,000 psig. These units come with a range of sensor elements, and are available with NEMA 4 and IP67 protection. Our adjustable pressure switches are field adjustable, allowing the end user the ability to adjust the set point of the switch in the field. Alternatively, our factory-set pressure switches are set by our professional staff at the factory to your exact pressure set point needs, and are not adjustable.

Compound Pressure Switches

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. 

Differential Pressure Switches

Differential Pressure switches measure the pressure differences between two points in an application and actuate when an end user pre-set actuation point is hit. Our snap action differential pressure switches are NEMA 4 rated and can withstand pressure spikes up to 9,000 psig. These devices have user set points from 0 to 250 PSI Differential and are capable of carrying light to moderate mechanical shock and vibratory loads.

  1. P100G High Accuracy Low Pressure Environment Pressure Switch

    P100G High Accuracy Low Pressure Environment Pressure Switch

    $90.50

    Part # P100G

    The 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.

    • Set Point Range: 0.10 to 15.0 PSIG, 2.75 to 415.2 In. H20
    • Max System Pressure: 15 PSIG
    • Temperature range: -65°F to +190°F (-54°C to +88°C)
