- Adjustable switch action point via knob,with intuitive pointer display.
- High repeatability for frequent response scenarios.
- Independent switch&pressure indication;no power loss impact on readings.
- Durable mechanical design,power-independent.
Description
LFBMR micro differential pressure gauge/switch is an integrated product combining pressure measurement & indication with differential pressure switch functions. It integrates high-precision, high-repeatability differential pressure switch functions into the micro differential pressure gauge. The pressure setting of the switch action point is adjusted via the regulating knob on the product surface, and the action pressure is indicated by the setting pointer. The switch function and pressure measurement & indication function do not interfere with each other, and even if the power supply is interrupted, the instrument reading remains unaffected.
