Vacuum sensors monitor negative pressures in suction lines, vacuum filtration and degassing systems — preventing pump cavitation and air ingress before they damage equipment or upset a process. Where a pressure transmitter watches the discharge, a vacuum sensor watches the suction side, catching the developing problem that starves a pump.
Catch cavitation and air ingress before they bite.
Excessive suction vacuum warns of insufficient NPSH before cavitation erodes the pump — key on dosing and process pumps.
Detects suction-line leaks that draw air — a leading cause of dosing-pump under-delivery (under-dosing).
Monitors vacuum on belt and drum filters and dewatering equipment for stable, efficient operation.
Confirms vacuum in degassers and off-gas systems handling volatile or gassing reagents.
A dosing pump that “runs” but doesn't deliver is often a suction-side vacuum/air problem — a vacuum sensor turns an invisible fault into an alarm. See under-dosing troubleshooting.
Tell us the suction duty and media and we will specify the vacuum sensor and integrate it into pump protection and dosing-system monitoring.
Vacuum sensors measure pressures below atmospheric, giving the feedback needed to run and protect vacuum-assisted processes such as degassing, evaporation, filtration and suction lift. Accurate vacuum measurement lets a control system hold the right operating point, detect a developing leak or blockage, and protect pumps and vessels from conditions they were not designed for. We select the sensor technology and range to the application — from rough process vacuum to finer duties — with attention to the wetted materials and the signal the control system needs. Correctly specified and sited, vacuum instrumentation keeps vacuum processes efficient, stable and safe.
