Pressure Switches

Pressure Switches

Transcat distributes the most reliable pressure switches for general purpose, air/water, gas and differential applications. The pressure switch will detect changes and open or close an electrical contact according to a predetermined set point. Differential switches sense pressure from both a low and a high pressure port and respond to the difference. Switches may be categorized according to their technology, such as diaphragm or piston. Our pressure device selection features switches with a wide scope of ranges to support virtually every application. We also offer Dwyer switch/gage combination instruments that measure and control positive, negative or differential pressures of air and gases.

 

Pressure Switch Buying Parameters

 

From length of service to cycle speed, the characteristics of a pressure switch will be affected by its technology. In addition to operating range and pressure sensor type, there are questions to ask about the switch, such as:

 

  • Is it process or media compatible?
  • Is the housing suitable for the application?
  • Can setpoint be adjusted?
  • What’s the operating temperature range?
  • Can it handle pressure spikes, and what is the max pressure?
  • What is the accuracy?

 

The Best Industrial and Process Switches

 

Dwyer Instruments A9 series switches are designed for controlling pressure with higher current capacity. These switches are used widely in steam cleaners, steam irons, and other pressure control systems. Dwyer’s switch/gages serve with versatility as highly repeatable pressure switches and precise gages. Ashcroft’s general purpose switches for pressure work within the full scope of process and industrial applications. They’re available with explosion-proof enclosures. Dwyer Instruments XP differential switches also offer explosion-proof designs and can feature a total pressure capability of 1500 psi.
