K-Tek Beta pressure and temperature switches

K-Tek’s Beta line of pressure and temperature switches have been certified for operation in Safety Integrity Level 2 (SIL2) environments. To obtain SIL2 certification, the products must be analysed based on quantitative data and tests indicating the length of time between failures and expected performance in the field.

The company’s Beta is claimed to be the only pressure switch range to provide a complete SIL2 pressure switch product offering. They can be integrated with the company’s SIL2 magnetostrictive transmitters, eliminating single mode failure and increasing the safety integrity rating of the entire level system.

The Beta line of pressure and temperature switches features spring-loaded, self-aligning diaphragm/piston sensors. Limited piston travel transmits pressure at the diaphragm directly to the microswitch; there are no intervening linkages or mechanisms and full protection is provided against high over-range pressure. The switches are engineered for maximum over-range protection of up to 399 bar. The spring-loaded piston also provides high resistance against shock and vibration and makes changing ranges as easy as changing the spring. The Beta W series include a separate adjustment compartment that allows for easy field calibration.
