These high-quality mechanical pressure switches have been developed especially for safety-critical applications. The great advantage of mechanical pressure switches is that no supply voltage is required for the switching process.
In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. Due to its compactness, the model PCS pressure switch can be installed in measurement environments with limited space. The robust switch enclosure from aluminium alloy or stainless steel 316L can withstand the rough and corrosive operating conditions of the process industry with working ranges of up to 1,000 bar.
The pressure switch is fitted with microswitches, which make it possible to switch an electrical load of up to AC 250 V, 15 A directly within a repeatability of 1 % of the set point.
Depending on the application, the appropriate variant for the contact version and the electrical connection can be selected; e.g., hermetically sealed microswitches are suitable for corrosive ambient conditions and DPDT contact versions for two separate circuits.
By using a diaphragm element with antagonist spring as sensor element, the model PCS pressure switch is extremely robust and guarantees optimal operating characteristics. For safety applications, the pressure switch is optionally available in a SIL 2-qualified or a SIL 3-qualified version.
