Non-Incendive Certified Sensors

Speed and Position Sensors, Signal Amplifiers, Signal Conditioners

Non-Incendive (Limited Energy / Increased Safety) sensors and signal conditioners are for use with Class I, Division 2 and Class I, Zone 2 classified areas. These sensors are designed for use in areas where the possibility of a hazardous gas is less likely. The internal protection components provide the means to prevent arcs, sparks and hot surfaces.

Versions of our Variable Reluctance, Amplified Variable Reluctance, RF Eddy Current, and Hall Effect Zero speed sensors are available. Certified versions of several Signal Amplifiers and Signal Converters are also available.

Applications

  • Flow metering
  • Engine and turbo speed
  • Anti-lock braking systems (ABS)
  • Traction Control systems
  • Hydraulic pump speed
  • Conveyor / Process speed
  • Process counting
  • Position sensing
  • Quadrature and Directional sensing
