Low-Pressure Differential Gauges with Color Indicator
A band of green, yellow, and red provides a clear indication of changes in differential pressure. Gauges are commonly used to indicate clogged filters.
- For Use With: Air, Water, Hydraulic Fluid, Carbon Dioxide, Nitrogen, Hydrogen, Argon, and Acetylene

Hazardous Location Electronically-Controlled
Precision Compressed Air Regulators
Intrinsically safe, these regulators cannot create sparks, so they’re safe to use in NEC Class I, II, and III, Division 1 and 2 hazardous locations. They translate electrical signals into steady output pressure for precise, repeatable motion. As the input signal increases, the output pressure increases proportionally within the regulating range. Pair them with sensors that produce the required input signal current or with programmable logic controllers (PLCs) for automatic setting adjustments. Install them in your air line after filters.
All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure.

Electronically-Controlled Precision Compressed Air Regulators
Designed for control applications that require high reliability and repeatability, these regulators translate electrical signals to output pressure. As the input signal increases, the output pressure increases proportionally within the regulating range. Use them where consistent pressure is needed to generate precise force and movement. Pair them with sensors that produce the required input signal current or programmable logic controllers (PLC) for automatic setting adjustments.
All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.
