Whitman Controls Corporation is an established leader in the manufacture of miniature pressure, differential pressure, vacuum and liquid level switches. The company has achieved this success by providing a quality product to customer specification at a competitive price.
Quality at Whitman is proven by a reliability rate substantially higher than industry standards and an ISO 9001 certified quality management system.
Pressure & Vacuum Switches
Whitman manufactures miniature pressure and vacuum switches for severe environment, low pressure, overpressure failure, economical, medium to high pressure, high accuracy and high purity applications. Varying interface options, pressure ratings, and set point options are available.
Miniature Temperature Switches
The Whitman miniature temperature switches offer reliable performance with repeatability of ±2% of the sensor capacity, will withstand over temperatures without affecting set point or the life of the switch, are resistant to vibration, have a narrow reset point range, and are offered in direct mount and capillary models.
Differential Pressure Switches
Differenial pressure indicator switches from Whitman Controls are rugged, have excellent by-pass characteristics, and are able to handle a wide variety of media with varying pressure ratings with adjustable set points available. Models are offered which can be installed in any position and are able to withstand moderate mechanical shock and vibration.
Liquid Level Switches
Whitman Controls has a large offering of liquid level switches. Each switch is sealed by a unique process which forms a superior seal and exceeds NEMA VI specifications for submersibility. No other manufacturer can provide this rating without the addition of special connectors or fittings. The Whitman Controls exclusive Red Seal allows for a reduction in production time and costs.
Hydrostatic Level Transmitter
The L95 Series Level Transmitters leverage high performance silicon piezoresistive pressure sensors as the lead sensing element. The transmitter measures the vertical depth of a column of liquid and converts this depth into standard amplified analog signals.
The L95 Series are IP68-rated devices, featuring a fullysealed structure and made from 304 stainless steel. The cable used in these transmitters is anti-oil, waterproof, and electromagnetic effect-shielded.
This device has a fully integrated structure with sensing element and signal conditioning circuit located and sealed in the probe housing. In application, the transmitter is submerged in the measured liquid with no external adjustment or calibration needed.
