ABSOLUTE MEMBRANE VACUUM GAUGE
A single-channel vacuum gauge with a digital display and analogue output 0 - 1 V. The set includes one pressure transducer AMPT 01, connecting cables and a rack module ACC. to DIN 43 700 electronic unit, containing analogue controller, 3 ½ digit LED display with floating point and power supply module. It is provided the ability of keeping constant pressure by direct control of EM valve or relay output. It is possible to adjust the set point in both cases by means of the front panel buttons.The absolute membrane vacuum gauge AMVG 01 is designed for measurement and control of dry, non-corrosive gases pressure in the range of 0,1 - 1020 mbar in vacuum systems and it is suitable to work in high power CO2 lasers.
The pressure transducer AMPT 01 consist of piezoresistive absolute membrane pressure sensor, based on micro-machined Si diaphragm, thermo-compensated and span laser trimmed, preamplifier and a thermo isolated plastics case.
