Working Mechanism

  • Ensure proper mounting of the pressure switch by considering factors like orientation and environmental conditions.
  • Set the desired pressure range using adjustable mechanisms or by selecting the appropriate pre-set range.
  • Connect the electrical leads or terminals of the pressure switch to the corresponding circuit or control system.
  • If required, calibrate the pressure switch by adjusting the setpoint or threshold to the desired pressure value.

Features

Ashcroft Explosion Proof Pressure Switches:

  • These switches are housed in 316L stainless steel enclosures for corrosion resistance.
  • Their explosion-proof housing gives uncompromising protection in hazardous environments.
  • These pressure switches offer a pressure range of -15 to 15000 psi and can handle temperatures from -40 to 193 degrees F.
  • They come in either factory-set or field-adjustable setpoints, allowing customisation based on specific pressure requirements.
  • These pressure switches feature a fixed deadband for consistent and precise switching between pressure states.

Hydro Vacuum LCA / LCS Pressure Switches:

  • These switches are useful in hydrophone systems for protection against pressure drops.
  • They feature IP43-rating for protection against dirt and water sprays.
  • These pressure switches can handle temperatures ranging from -5 to 40 degrees C and relative humidity up to 50%.

Frequently Asked Questions

Can a pressure switch be calibrated?

Yes, pressure switches, like many other instruments, can be calibrated. Users must calibrate them to ensure accuracy and reliability.

How is a pressure switch different than a sensor?

Pressure switches protect the machine and its operators, whereas sensors relay a pressure readout to a remote location.

What influences the response time of these miniature pressure switches?

The response time of a miniature pressure switch can vary depending on the design, construction and operating conditions.
