About Series A3 Digital Differential Pressure Gauges

Series A3 Digital Differential Pressure Gauges

The series A3 is a patent pending microprocessor based controller for positive, negative, and differential pressure as well as velocity and flow. The Series A3 includes (2) 8A SPDT relays and an associated software package that allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done from a user friendly menu on the LCD display or uploaded using an Opti Link programming key. The LCD also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate many applications. Compared to other mechanical products, the Series A3 has a significantly reduced depth, an improved look, and better performance at a lower price

Reliable and Versatile Pressure Measurement

Designed for industrial environments, the Series A3 digital gauge provides accurate differential pressure readings for air and non-corrosive gases. Its MEMS-based sensor technology, coupled with a microprocessor-controlled digital display, guarantees consistent and precise monitoring across various selectable ranges, from 0500 Pa to 030 kPa. With IP40-rated frontal protection and robust ABS/aluminum housing, it suits demanding applications.

Flexible Installation and Signal Output Options

The Series A3 supports both panel and wall mounting. It offers optional analog outputs4-20 mA or 0-10Vmaking it adaptable to a wide range of process automation and control systems. Pressure connections use barbed ports for 6mm tubing, ensuring secure and straightforward setup in HVAC, cleanrooms, and filter monitoring.

User-Friendly Interface and Smart Features

A 4-digit LCD and intuitive front panel push-button re-zero provide straightforward control and real-time clarity. Audible and visible high/low set-point alarms offer proactive alerts, while battery operation allows for portable or remote installations without compromise on accuracy.

FAQs of Series A3 Digital Differential Pressure Gauges:

Q: How do I install the Series A3 Digital Differential Pressure Gauge?

A: The gauge can be mounted either on a panel or wall using the supplied mounting bracket and screws. Pressure ports are designed for 6mm tubing, and the electrical output (if chosen) connects via the specified terminals. A detailed user manual is included for step-by-step installation guidance.

Q: What gases can the Series A3 measure, and what is its accuracy?

A: This device is suitable for measuring differential pressure of air and other non-corrosive gases. It offers high accuracy at 1% of full scale, ensuring precision in critical applications.

Q: When should I use the alarm function on the Series A3 gauge?

A: The alarm function can be used to set high or low pressure thresholds. When these limits are exceeded, the gauge emits audible and visible alerts, providing early warning for process deviations. This function is ideal for safety monitoring in controlled environments.

Q: What are the power supply options for this pressure gauge?

A: The Series A3 operates on three standard AA batteries, making it portable and convenient, or it can be powered with a DC 9V adapter (optional) for continuous, stationary use.

Q: How do I reset the pressure reading to zero?

A: Zero adjustment is performed easily with the push-button on the front panel, allowing you to re-zero the device after installation or routine maintenance for consistent performance.

Q: Where can the Series A3 be used besides industrial settings?

A: In addition to industrial applications, the Series A3 is well-suited for cleanrooms, laboratories, HVAC systems, and any environment requiring precise air or non-corrosive gas pressure measurement.

Q: What are the main benefits of using the Series A3 Digital Differential Pressure Gauge?

A: This gauge provides quick response, high accuracy, adjustable output options, easy installation, and reliable alarm notifications, contributing to safer and more efficient monitoring of pressure in critical systems.
