The Series A2 digital differential pressure gauge is a patented microprocessor based digital pressure gauge for positive, negative, and differential measurement designed to be a direct replacement for mechanical gauges. The Series A2 differential pressure gauges utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the A2 is available with 0.5% or 0.25% accuracy. The A2 pressure gauge has an optional 4 – 20 mA output for applications requiring an output signal. The A2 features a bright ½" LED display and process arch, which gives the gauge improved readability and precision. The A2 digital differential pressure gauges also feature 5 user selectable engineering units including in. w.c., mm w.c., cm w.c., kPa, and Pa. The Series A2 offers an improved look, and performance compared to mechanical gauges.
