Description
The Trerice 800B4002LA100 Dry Utility Pressure Gauge converts system pressure into manual dial movement through a Bourdon tube sensing element that responds to internal force changes. The unit features a 4-inch dial diameter for clear readability and a 1/4-inch MNPT rear connection intended for threaded installation into process lines in HVAC systems. It operates by elastic deformation of the sensing tube, translating pressure variation into pointer displacement across a calibrated scale. It provides direct visual indication of pressure levels, assisting in the observation of operating conditions and the identification of abnormal variations within mechanical systems.
