Model 106 Bellow Type Differential Pressure Gauge & Switch
Brand: Mid-West InstrumentModel’s106 (±1/2% or ± 1% Full Scale Accuracy) System pressure is applied to the internal volume of a bellows and mechanical linkage assembly.
As pressure changes, the bellows and linkage assembly move to cause an electrical signal to be produced or to cause a gauge pointer to move.
Model’s 106 assembly incorporates a bi-directional relief valve which provides over-pressure protection in both directions.
When over-pressured from the high side, the valve is opened by a mechanical stop as the sensing element deflects to its maximum travel.
Features- Diaphragm Bellows design provides a simple, compact, accurate, direct-acting, low range high accuracy differential pressure indicator
