Series A3 Digital Differential Pressure Control/Gauge with Flow and Velocity Function and Optional 4-20 mA Output

• Mounts in industry standard hole
• Displays pressure, velocity, or flow
• Bright 1/2 inch 4 digit numeric LED pressure indication
• Universal Power 24 to 240 VAC or VDC
• Digital set point programming and calibration
• 14 selectable engineering units
• Optional 4-20 mA output

The Series A3 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 A3 utilize an extremely stable piezoresistive sensing technology to give a standard full scale accuracy of 1%. For applications requiring better accuracy, the A3 is also available with 0.5% or 0.25% accuracy. The A3 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 A3 features a bright ½" LED display and LCD programming display, which gives the gauge improved readability and precision. The A3 also features 14 user selectable engineering units. The Series A3 is ideal for applications ranging from clean rooms to dust collection.
