Differential Pressure Switches & Relays
Mid-West Instrument’s differential pressure switches and relays provide real-time process visibility. Using hermetically sealed reed switch technology, they alert at preset values and control equipment accordingly.




Switches & Relays For DP Gauges
You get field-adjustable setpoints within a predefined range, so you can dial in exactly what you need. Choose between SPST or SPDT outputs depending on your setup. Most models come in NEMA 4X enclosures or clamp-on styles, with optional approvals for hazardous locations including ATEX and North American divisions.
When there is a need to switch a heavier load, the relay options handle high-power circuits and inductive equipment like solenoids and motors. All switches come preset to 50% full-scale unless you specify otherwise. CE marked and RoHS compliant.
