The series A4 is a microprocessor based digital pressure gauge control for positive, negative, and differential pressure measurement. The differential pressure control is fully programmable and includes the ability to read directly in velocity or flow. The Series A4 utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the A4 is also available with 0.5% or 0.25% accuracy. The A4 is available as a gauge or a control with (2) SPDT relays and optional 4-20 mA output for applications requiring a transmitter output. The A4 features a bright ½" LED display and OLED programming display, which gives the gauge improved readability and precision. The A4 also features 14 user selectable engineering units. The Series A4 is ideal for applications ranging from clean rooms to dust collection.
