Pressure Switch

Pressure Switch


Basic Construction:

  • One piece injection molded switch pan Elastomeric diaphragm eliminates the need for an oil barrier
  • Field adjustable pressure set points. Factory calibration available upon request
  • Built in over pressure protection designed to eliminate stress on other critical operating components
  • UL Recognized, Canadian and United States, as an operating, limit or safety control
  • Available with CE approved electrical snap switches

 

Commonly used as an interlock device to sense air, gas or water pressure at a specific point, Series 4000 switches provide on/off control of:

  • Electric or gas heaters
  • Pumps
  • Small air compressors
  • Electric strip heaters in VAV systems
  • Waste oil heating systems
  • Food processing equipment
  • Residential boilers
  • Other electrical equipment in pneumatic, gas or fluid flow systems

  • Maximum Operating Pressure and Hydrostatic burst pressure, varies based on model configurations. Consult factory for specific application needs.
  • Electrical ratings to 25 amp, 250 VAC
  • Field tested critical components specifically selected to operate reliably in temperature extremes of 32° to 190°F (0°C to 88°C) 100,000+ cycle life under full mechanical, electrical and thermal loads DESigN FLEXiBiLiTY: Tecmark's manufacturing philosophy is unique. In an effort to provide you with a product that is most suited to your application, Series 4000 switches incorporate numerous interchangeable components for the ultimate in design flexibility. This means a product tailored to your needs without the high price and long lead times associated with custom manufacturing.

  • Pressure ranges as low as 2" WC up to 11 PSI (500 Pa to 76 kPa) SPST or SPDT switching logic
  • 1/4" male quick connect for electrical connections
  • A variety of mounting pan and pressure fitting materials; stainless steel, injection molded plastic and plated steel
  • Wide array of pressure fittings; 1/8" NPT male, 1/4" NPT male, 3/16" barbed, 1/8", 3/16" or 1/4" compression, or 1/8" NPT female with 1/2" conduit male external thread for mounting
  • Optional pressure set point locking mechanism
  • Specialty diaphragm materials; Buna-N, EPDM, Hydrin
