Pressure Switches & Gauges

L91 Proportioning Pressuretrol® Controllers are Series 90 Modulating Pressure Controllers that provide direct control of modulating motors or valves used on automatic burners or steam heating systems.

Mercury free pressure controls with automatic limit protection for pressure systems up to 300 psi, or oil burner systems up to 150 psi. Can be used with steam, air, non-combustible gases, or fluids non-corrosive to the pressure sensing element.

For monitoring gas and air pressures, also for biologically produced methane, with hand wheel for switching point adjustment, can be used as ''special-design pressure switch'', EU certified, AGA, EAC approved, RoHS compliant

For monitoring gas and air pressures

For monitoring air and flue gas pressures, for positive pressure, negative pressure and differential pressure

For monitoring air and flue gas pressures, for positive pressure, negative pressure and differential pressure, FM and CE approved

For monitoring air and flue gas pressures, for positive pressure, negative pressure and differential pressure

Line voltage pressure controllers that provide operating control or automatic limit protection for pressure systems of up to 4 psi (27.6 kPa). All models have Microswitch snap switches to open or close a circuit on a pressure rise.

Diaphragm pressure switches with micro switch (silicone-free versions available) for monitoring air pressures on air-conditioning, ventilation and extraction systems, for positive pressure, negative pressure and differential pressure.

Complete selection of pressure indicators for use in combustion systems

Pressure gauges with capsule element or Bourdon tube for pressure display, positive-pressure-proof, with zero point correction, for gas and air.
