Bestech Australia presents the model 322S low cost pressure switches, from BCM Sensor. These pressure sensors integrate the pressure measurement and electrical switching together, so that when the input pressure increases to an upper limit, the moving parts of the device are enabled and this results in the associated electrical contacts being disconnected (or connected). If the input pressure decreases below a lower limit, the unit is switched back to the initial position.

Features of the pressure switches include:

  • The pressure switches are composed of a common spring tube which provides the moving parts of the electrical contacts, which are isolated and located inside the housing
  • As the electrical contacts of these pressures switches can be disconnected and connected again by the variation of input pressure, actuators can be disconnected and connected in an industrial automation system to control the pressure within its upper and lower limits
  • The pressure switches have a switching accuracy of ±0.1 bar and has an operating temperature range of -35 to 120°C
This series of pressure switches are widely used to generate enable/disable control signals or alarm signals to prevent hazards in industrial processes. They can find applications in small air-compressors or complete pressure systems in many industries, including in power plants, petroleum and oil-refinery industries, chemical, food and metallurgy industries.
