Product category : Pressure gauges & indicators

A series of contact pressure gauges are designed and manufactured by mtc.The sensing element is bourdon tube/diaphragm/capsule. Some of the technical features of these pressure gauges are: gauges serve to measure and control pressures by switching on and off electrical equipments such as pumps, motors, turbines, blowers or audible or visible alarms for signalling irregularities. These pressure gauges are available on 100 mm and 150 mm dial sizes to meet every range of service from minimum 100 mm wc to 1,000 kg/cm2. Magnetic contact device is highly resistive to vibrations and fluctuations having sparkless operation thus, it minimises arching damage to the contacts and giving longer life-span. Following are some of the constructional features of these pressure gauges which include: electrical contact terminals are positioned by a removable key at the required make/break setting against the instrument dial. During the operation, when. The instrument pointer passes this setting, the contacts are broken or made by picking up or leaving the moving arm against the pressure of a hair spring whilst the set arm remains stationary. Suitable material is used for contacts having high resistance to arching and good conductitivbility range to high voltage/low current requirements. For increased contact performance under specific adverse conditions, alternative alloy contact materials can be offered on request. A junction box is also provided with these gauges on a periphery of the case for radial/ bottom connector instruments, and on the back side for back connection gauges.
