Series A1

Digital Differential Pressure Gauge

The series A1 is a patent pending microprocessor based digital pressure gauge for positive, negative, and differential measurement designed to be a direct replacement for mechanical gauges. The Series A1 utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the A1 is also available with 0.5% accuracy. The A1 also has an optional 4-20 mA output for applications requiring an output signal. The A1 featuresabright½”LED display, which gives the gauge improved readability and precision. The A1 also features 5 user selectable engineering units including in. w.c., mm w.c., cm w.c., kPa and Pa. The Series A1 offers an improved look and performance compare to mechanical gauges for a similar price.
