B-Guard Cat
GasTech Australia has used the latest low power switch mode technology for the detection of Combustible gas in LEL and ppm levels. This unique amplifier has a built in capabilities to be either a 4-20mA Source or sink, simply by the positioning of 2 jumpers. It has a head voltage operation from 1.4Vdc to 14Vdc, which will cover the full range of low voltage and high voltage sensors. It is also designed for set gain control for extra low sensitivity for ppm detection. The use of a precise amplifier and precise offset voltage allows this to be one of the most stable amplifiers on the market. today. Advanced calibration minimises interference between zero and span adjustment, which enables quicker and more accurate calibrations. All components are low profile surface mount designed for ease of installation and years of trouble free operation.
