Applications

Pressure Switches & Transducers

  • LFS02

    • Designed as an economical interface between pressure systems and Printed Circuit Boards.
    • Can be used as a gauge or differential pressure switch with almost no hysteresis. It is applied to detect both positive and negative pressure
    • Features include body design that allows the pressure ports to be rotated. Various terminal styles including flying leads available
  • LFAS

    • Pressure cut-off switch offering exceptional thermal and dimensional stability at high temperatures.
    • Suitable for use in contaminated atmospheres; e.g. combustion flues
    • Designed to meet the low pressure, high temperature specifications of fanned gas and similar appliances, where differential pressures form part of an integral control system
  • LF31

    • Pressure, vacuum and differential variations are available, capable of sensing very low set points and switching current up to 5A resistive and 2.5A inductive
    • Designed for use in HVAC applications, where reliable air proving is critical to both performance and customer safety, the LF31 is particularly suitable for use in gas-fires and water heaters
    • Smaller and lighter than any other HVAC pressure switch, the LF31 is built for the same temperature range and operating life as conventional switches
    • The LF31 will perform equally well in other applications which demand low OEM unit cost, robust design, set point accuracy, and high reliability
  • LF25

    • Designed for pressure control, with higher current capacity, the LF25 provides SPST or SPDT contact form and switch dead band (also referred to as mechanical differential or hysteresis)
    • It incorporates high-quality miniature snap-action switches, which are diaphragm operated. The diaphragm material can be selected for the operating medium, temperature range and other parameters.
    • During the development of a specification, actuation point can be adjusted by the designer, with factory setting required for production
  • LF32

    • Capable of sensing very small changes in pressure, the LF32 switch is widely used to control flue aeration and to monitor fans in air conditioners.
    • It is also suitable for over-heating and frost protection in industrial cooling systems. Its design allows the set point to be seen and easily adjusted by the operator.
