SAR - Snap Acting Relay
Compact snap acting relay providing precise pressure switching for pneumatic control systems.
Provides precise pressure switching with an adjustable setpoint and minimal hysteresis for reliable control.
Ensures secure and stable operation with a lockable adjusting screw and safety design to prevent unintentional changes.
Withstands harsh environments with an anodised aluminium housing designed for extreme conditions.
Features
The SAR Snap Acting Relay is a narrow-band pneumatic controller designed for precise pressure switching in pneumatic control systems. It operates with an adjustable setpoint, directing full supply pressure to the output when the input pressure exceeds the spring setting. If the input pressure drops below the setpoint, the output equals the signal pressure. This rapid switching mechanism ensures accurate and responsive operation. Constructed from anodised aluminium, the SAR is suited for harsh environments, including offshore and sandstorm conditions. With a compact design, lockable adjusting screw, and precise low-hysteresis switching, it is ideal for integrating with pneumatic-controlled positioners.
