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.
1NO/NC, 2NO/ NC, 2NO/ 2NC Contact elements – Used for control of pressure / audible / visible alarms. Choice of low action normal contact, snap action magnetic contact or inductive contact, adjustable with different mode of switching action
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
