Description

Micro high quality Bourdon Operated Differential pressure gauges are built with stainless, chrome- nickel steels (i.e. S.S.316 or better). They can be used under all operational conditions, practically without limitations to measure differential pressure of two separate inputs on one dial indicator. The pressure gauges are suitable for extreme measuring conditions. The gauges can be used for all liquids and gases used in processes except for those having a high viscosity, or which are liable to crystallized Technical Specifications: (Confirming to EN-837-1 & IS-3624) Nominal size – Ø 100 & 150 mm Accuracy – ±2% of FS Case & Bezel – SS 304 case with Snap Action bayonet lock type bezel (SS 316 Optional) Ingress Protection – IP 65 as per EN 60 529 or IS/IEC 60 529 IP 68 as per IS/IEC 60 529 - Optional Pressure element – Bourdon Tube SS 316 / SS 316L / SS 316Ti (Monel 400 Optional) Static Pressure – 1.5 Times of Pressure Range Movement – SS 304 Double bearing friction less type Socket – SS 316 / SS 316L (Monel 400 Optional) Dial – Aluminium – Pre-coated White with black marking Pointer – Aluminium – Black Finish Micro Zero Adjustment Window – 4 mm thick Toughened Glass (Safety / Shatter Proof Optional) Joints – Argon welded Sealing gasket – Neoprene Rubber (EPDM Optional) Blow out protection – Neoprene Rubber (EPDM Optional) On Back of Case Pressure relief – Top of Case with Vent Valve (On Request) Process Connection – (HP & LP) 1/4” / 3/8” / 1/2” BSP / NPT / BSPT (Male) M20 X 1.5 (Male), Other Male or Female Conn.
