Description
Mechanical pressure switches have been developed to switch an electrical contact when a pressure in a process exceeds defined limits. The pressure can be too high or too low. Pressure switches have no precise local indication, no analog output signal and need no electrical power supply. These simple devices are purely optimized to guarantee an excellent repeatability and reliability of the switching behavior.
Pressure switches without power supply are used in safety critical applications.
Many applications like monitoring of pressurized chambers, tank levels, valves and compressors benefit from the safe and simple solutions.
Pressure switches are available in EEx d versions for hazardous areas. Assembly with diaphragm seals, pressure switches can be used also in applications with critical process fluids or for hygienic installations in Food & Beverage or Pharmaceutical productions.

Technology
Baumer Technologies mechanical pressure switches are designed for alarm setting if pressure limits are exceeded or for pressure regulation.
Depending on the pressure range the sensing element is a diaphragm, a piston or a bellow. The sensing element is pressurized and works against the adjustable force of an internal spring.
The deflection of the sensing element operates a mechanical microswitch. The value of the setpoint is defined by the adjustment of the spring and can be adjusted in the factory or by the customer. For several microswitch types, the deadband is also adjustable. This allows separate definition of setpoint and reset point.
Baumer Technologies pressure switches provide an excellent repeatability in a compact design. The working principle is fully mechanical and requires no electrical power supply. Wiring has to be done only to read the microswitches.
