Single/double snap action magnetic Electrical Contact Pressure Gauges are available in 100mm & 150mm dial size. These gauges serve for the measurement and control of pressure by switching 'on and off electrical equipments. Thus eliminates the need of separate switches for equipments such as pumps, motors, turbines, blowers for audio/visual alarms for signalling irregularities. These contacts may be used under almost all operating conditions, they are largely immune to vibration. The contact pin carrier of the indicator is equipped with an adjustable magnet which attracts the contact arm just prior to reaching the indicator. This prevents arcing and burning of contact pins.Electrical contact can be used up to 380 volts ac/dc and switching capacity up to 30 watts/50va. The current rating must not exceed 1 amp.

We provide Weatherproof Pressure Gauges at very affordable prices to our valued customers.

Glycerine Filled Pressure Gauges are installed on Powerpacks, Hydraulic Machinery, Pumps, Compressors, Power Plants, Pipelines and Transmission Stations where Vibration & Pulsation are destructive factors. Glycerine filling makes the difference, the movement is submerged and constantly lubricated. The damaging effect of pulsation and vibration are minimised Pointer flutter is virtually eliminated because both the liquid filling and a restrictor screw in the Socket help in dampening pulsation.

Low Pressure Diaphragm & Capsule Gauges

Diaphragm gauges are suitable for measuring pressure of all kind of fluid and gaseous medium. The measuring element is a sensitive corrugated diaphragm fixed between two flanges. For slurry and viscous liquids flanged connections can also be incorporated. Low Pressure Bellow Capsule Gauge are designed for non-corrosive and non-aggresive application.
These Gauges have bellow capsule which is composed of two corrugated metal discs of Brass / Stainless Steel joined by brazing / argon arc welding. A rise pressure will cause the corrugated Capsule / Diaphragms to expand and this motion is transferred to the indicator through sector, pinion movement mechanism. A similar type of low pressure built-in capsule gauge can also be offered having almost similar kind of mechanism.

Bellow Differential Pressure Gauges

The pressure element of these instruments has two S.S.316 bellows, balance mounted. The value shown on the dial is the difference between two input pressure or depressions coming in to each bellow. Differential Pressure Gauges are entirely made of S.S.316 wetted parts, therefore they offer the same corrosion resistance (inside and outside) as the Bourdon Pressure Gauges. Moreover the mechanical resistance of the bellows allows important one-sided overpressure, compare to the differential pressure (up to 20 times in some cases). All differential pressure gauges are used for measurements of flow, level, filter clogging, pressure drop measurement, air conditioner & chemical processor.

Diaphragm Sealed Pressure Gauges are designed to measure the corrosive fluids pressure, where suitable material for bourden tube is not available.
The Diaphragm assembly withstand various corrosive actions encountered and seals the Bourdon tube from the process fluid. The displacement of the liquid filled in the Bourdon tube, through movement of the diaphragm, transmits the process pressure to the gauge. The Diaphragm sealed connections are available with threaded type, flanged type and capillary type mountings.
