About Digital Differential Pressure Control - Series A4

Digital Differential Pressure Control - Series A4

The Series A4 digital differential pressure controller is a patented microprocessor based pressure controller for positive, negative, and differential pressure as well as velocity and flow. The Series A4 differential pressure controller includes (2) 8A SPDT relays and an associated programming menu 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 OLED display or uploaded using an Opti-Link programming key. The OLED 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 A4 digital differential pressure controller has a significantly reduced depth, an improved look, and better performance at a similar price.

Customizing Options Available

Versatile Measurement and Control

The Series A4 is engineered for precise differential pressure measurement in a wide range of applications, handling air and non-corrosive gases effectively. With a scale range of 0 to 1000 Pa (customizable), and high accuracy (1% F.S.), it supports demanding industrial requirements. Its digital processing and stainless steel sensor construction ensure reliable long-term operation.

User-Friendly Interface and Rapid Configuration

Equipped with a digital keypad for set point adjustments and a bright digital display, the Series A4 enables intuitive operation and quick on-site calibration. The LED or LCD screen provides clear real-time pressure readings, while panel mounting and included accessories streamline installation. Audible and visual alarms further enhance operational safety.

Durable and Safe by Design

Protected by an IP54 ABS enclosure and featuring stainless steel sensors combined with EPDM seals, this device is built to withstand harsh industrial environments. The Series A4 operates within a temperature range of 0C to +60C and can handle humidity lower than 85% RH, offering robust and reliable performance with minimal maintenance.

FAQs of Digital Differential Pressure Control - Series A4:

Q: How does the Digital Differential Pressure Control - Series A4 measure and display pressure?

A: The Series A4 utilizes a microprocessor-based pressure transmitter to ensure precise measurement of differential pressure in air or non-corrosive gases. Results are shown on a digital LED or LCD display, making real-time monitoring straightforward and reliable.

Q: What output options does the Series A4 provide for integration with control systems?

A: It offers both relay outputs for direct control and analog outputs (4-20mA or 0-10V) that can connect to PLCs, building management systems, or data loggers, facilitating seamless integration into automation setups.

Q: Where is the suitable place to install this device, and what mounting options are available?

A: The device is designed for panel mounting using the included screws, making it ideal for installation in control panels, HVAC systems, clean rooms, and other industrial locations that require precise differential pressure monitoring.

Q: What is the process for adjusting the set point on the Series A4?

A: Users can adjust the set point through the digital keypad on the front panel. This interface allows for fast and accurate configuration, ensuring optimal performance tailored to specific process requirements.

Q: When will the alarm function activate and how are alerts signaled?

A: The built-in alarm activates when the pressure crosses preset limits. The device provides both visual and audible alarms, ensuring operators are immediately notified of critical changes in pressure conditions.

Q: What benefits does the IP54 rating and construction materials offer?

A: The IP54 rating protects against dust and splashing water, while the ABS enclosure and stainless steel sensors contribute to durability, even in demanding industrial environments. This ensures long service life and minimal risk of failure.
