Pressure & Vaccum Gauges
ELECTRIC CONTACT & DIFFERENTIAL GAUGES

These gauges can be used for different monitoring, measurement and control of line pressure by switching “on or off” electrical equipment. Contacts mounted on mechanical pressure Gauges -“Make or Break” an electronic control cycle depending on the position of the Instrument's pointer. The product eliminates the need of a separate switch.

2. Differential Pressure Gauges

These gauges are intended for measuring the pressure differential existing across two media or two parts of a system. The pressure element separates the two pressurized media, and deflects proportional to the difference in pressures between the media, irrespective of the absolute pressures applied. This deflection is converted into the rotation of a concentric pointer on a dial, similar to regular pressure gauges. The absolute value of either of the pressures is not usually indicated
