Model 105 Bellow Type Differential Pressure Gauge & Switch
Brand: Mid-West Instrument
Model’s 105 (±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 105 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
- Easier and less expensive to service/repair than competitive units
- Working pressures of 500, 1,500, 3,000, or 6,000 psiG (400 bar)
- Housing materials: Aluminum, Brass, Carbon Steel, or 316L S.S
- Internals: Stainless Steel Diaphragm Bellows
- Available: Elastomers: Buna-N, Viton, Neoprene, Ethylene Propylene
- Mechanical over-range protection high to low and low to high
- Weather resistant case of Engineered Plastic / Shatter resistant acrylic lens
- Panel Mounting Kit Standard
- Uni-directional or Bi-directional dials are readily available
- Gauges are optionally available with one or two switches which offer’s the ability to have alarm or control
