Pressure Gauges
 
Pressure gauges are devices used for measuring the pressure of a gas or liquid. These gauges have been designed to withstand the most demanding environments & are offered in a wide assortment of dial sizes, case styles and wetted parts materials.
 
  Bourdon Type Pressure Gauge  
   
These are used for measurement of pressure and vacuum and are suitable for all clean and non-clogging liquid and gaseous media. The Bourdon Tube is a thin walled tube of oval cross section which may be of ‘C’ form or spirally wound. This tube expands when pressure is applied internally; this expansion is converted into rotation of a concentric pointer with a gear movement. C-type Bourdon tubes are used for low pressure ranges and helical / spiral tubes for higher pressure ranges.

  Capsule Type Pressure Gauge  
   
Capsule Pressure gauges are designed for measuring low/very low pressures and vacuum. The pressure medium needs to be gaseous. The capsule consists of two diaphragms joined and sealed around their circumference. Several such capsules may be combined to enable measurement of very low pressures.
