Differntial Pressure Gauge

Bellow Type Differential

MICRO high quality bellow operated differential pressure gauges are built with stainless, chrome- nickel steels (i.e. S.S.316 or better) mounted on a force balance frame, enables direct reading of the actual differential Pressure. They can be used under all operational conditions, practically without limitations. Their concept combines sturdy design and high measuring accuracy. Each bellow of the instrument can withstand full static pressure without any damage or shifting being caused to the instrument.
