Pressure Gauges

Pressure gauges give a local reading of pressure on pipes, pumps, compressors and vessels without power. Seven Star LLC, an independent supplier in Muscat, supplies mechanical and digital pressure gauges from WIKA, Ashcroft, NOSHOK, Additel, Dwyer, Palmer Wahl, Murphy, Druck and Yokogawa to customers in Oman and the GCC.

Types of pressure gauge in this category

Bourdon tube gauges such as the WIKA 212.20, 213.53 (liquid filled), 232.30, 233.30 and 233.50 safety pattern, and NOSHOK 400/500 stainless gauges serve general and process duty. Diaphragm gauges like the WIKA 432.50 handle viscous and corrosive media, and differential gauges such as the WIKA 700.01, NOSHOK 1000 and Dwyer Magnehelic 2000 monitor filters and flow. Digital gauges and test gauges including the WIKA CPG1500, Ashcroft 2089, Additel ADT681A, Palmer Wahl DSPG and Druck DPI 705E are used for testing and calibration, and Murphy Swichgage instruments add alarm contacts.

How to select a pressure gauge

Choose a range so the normal reading is around the middle of the scale. Then select dial size, accuracy class, case and wetted materials, liquid filling for vibration and pulsation, and process connection and mounting. Add a diaphragm seal, snubber or siphon for difficult media or steam.
