Stewarts manufacture a vast range of pressure and differential pressure gauges. For the optimal solution and the widest range of applications, there is a choice of measuring systems in bourdon tube, diaphragm element and capsule element technologies.

For the various requirements in industrial and process instrumentation there are pressure elements in copper alloy, stainless steel or special materials available. Unless stated otherwise all Pressure Gauges are calibrated in accordance with EN837‐1 to an Accuracy of Class‐1.

We have also developed a number of specialised gauges:

  • VIBRAGAUGE® – to alleviate problems caused by Vibration;
  • SNUBBAGAUGE® – to alleviate problems caused by Shock and Surge;
  • NITELITEGAGE® – for use in Dark Areas (Luminescent Dial & Reflective Pointers).

We design and manufacture pressure gauges for customer’s special requirements on request.
