PMPSW100

The SPT series electronic pressure switches are suitable for a wide range of applications, including energy, gas, chemical processing, HVAC systems, and fuel cell technologies. They are available with either oil-filled or stainless steel sensing elements, supporting both gauge and absolute pressure measurement. With a pressure range from 60 mbar to 2000 bar, these switches meet the demands of various industrial fields. Signal processing is managed by an ASIC (Application-Specific Integrated Circuit) for enhanced precision and reliability.

Product Features

Featuring high dielectric strength with a seal-less, weld-free design, this device incorporates ASIC-based signal processing, offers high integration density, vacuum sealing without elastomers, and provides flexible customization options.
