LPS Series Low Pressure Switching Monitor Q & A

+What is a low-pressure switching monitor used for?
A low pressure switching monitor is used to measure and control very small pressure differences in systems such as HVAC ducts, cleanrooms, and filtration systems. It triggers alarms or control actions when pressure exceeds predefined limits, ensuring system stability and safety.
+How does the LPS Series prevent false alarms?
The LPS Series includes an adjustable time delay (1–30 seconds), allowing users to filter out short-term pressure fluctuations. This prevents nuisance trips caused by transient spikes or momentary disturbances.
+Can the LPS Series output signals to a control system?
Yes. In addition to switch outputs, the LPS Series offers optional analog outputs (4–20 mA or 0–10 VDC), enabling integration with PLCs, SCADA systems, or building management systems.
+What makes the LPS Series different from a traditional pressure switch?
Unlike standard pressure switches, the LPS Series combines digital display, dual alarm switching, and optional analog output in a single device. This reduces the need for separate gauges, transmitters, and switches while improving visibility and control.
+What industries benefit most from low differential pressure monitoring?

Industries that require precise environmental control—such as semiconductor manufacturing, pharmaceuticals, and cleanroom-based processes—benefit most. These applications rely on accurate pressure monitoring to maintain safety, compliance, and product quality.
