Print pageSnap-Action, Air Relay Pressure Switches Can Be Fine Tuned
K-TEK Corp., a manufacturer of instrumentation for level, pressure, and temperature measurement, has announced the BETA Air Relay, a new, pilot-operated, snap action pneumatic switch from BETA N.V. The switch features a patented, snap-action mechanism that is said to do away with problems associated with throttling bands. Unlike other pilot-operated vent valves, the Air Relay can be fine-tuned for accurate increasing or decreasing action, according to the company.
The switch features a narrow deadband, as low as 10 mbar, and supports pilot supply and signal pressures up to 7.0 bar.
Designed for valve control, bleed-off shut-down, or alarm applications - both offshore and on - the BETA Air Relay can also be safely used in hazardous areas, including Zone 0 (no spark) applications. The switch is available in two configurations: TYPE SA for Normally Closed (N.C.) operation and TYPE SB for Normally Open (N.O.) operation.
The BETA Air Relay has been certified by KEMA for use in potentially explosive atmospheres.
