Description: Local‑mounted indicating instrument for measuring pressure difference between two process points. Available in mechanical pointer‑type and digital‑display variants. It provides direct differential‑pressure readouts without additional calculation, and is deployed within dust‑removal & filtration systems to monitor filter‑resistance variations.
Pointer‑type differential pressure gauges feature two pressure tap ports: High‑pressure (H) and Low‑pressure (L). Internal diaphragms or bellows sense the pressure difference across the two ports and drive the pointer via magnetic‑coupling or mechanical transmission for direct visual reading. Pure‑mechanical versions require no power supply. Digital‑type units integrate built‑in differential‑pressure sensors for numerical readout; selected models support alarm triggering and PLC signal output.
