Product Overview
MAMAC Systems A-523 Room Pressure Pick Up
The MAMAC Systems A-523 Room Pressure Pick Up is a wall-mounted sensing accessory that transfers a room-pressure reference to compatible low-pressure monitoring equipment. It is intended for positive or negative-pressure spaces such as laboratories, hospital operating theaters, and clean rooms, and the manufacturer specifically identifies the MAMAC PR-274 and PR-275 low-pressure sensors as supported interfaces.
The A-523 may be flush mounted or fitted to a standard 2-inch by 4-inch electrical junction box, making it suitable for replacement or new room-pressure sensing points where its dimensions, pressure limit, and sensor compatibility match the system requirements.

FAQs:
Q: What does the MAMAC Systems A-523 Room Pressure Pick Up do?
A: The A-523 establishes a room-pressure pickup point that can be connected to compatible low-pressure sensing equipment. It is designed for spaces maintained at positive or negative pressure, including laboratories, hospital operating theaters, and clean rooms.
Q: Is the MAMAC A-523 compatible with PR-274 and PR-275 low-pressure sensors?
A: Yes. MAMAC Systems specifically states that the A-523 is designed to interface with its PR-274 and PR-275 low-pressure sensors. Compatibility with other sensors or transmitters should be confirmed separately.
Q: Where is the MAMAC Systems A-523 commonly used?
A: The A-523 is intended for rooms and controlled environments maintained under positive or negative pressure. Applications include laboratories, hospital operating theaters, and clean rooms; suitability for a specific project still depends on the required pressure-monitoring design and associated sensor.
Q: What are the pressure and temperature limits of the MAMAC A-523?
A: The manufacturer specifies a maximum pressure of 10 PSID and an operating temperature range of 32°F to 158°F, or 0°C to 70°C. These limits apply to the A-523 pickup assembly and should not be confused with the measurement range or environmental limits of the connected pressure sensor.
Q: How can I confirm that A-523 is the correct room pressure pickup for my system?
A: Confirm that the existing part or project documentation calls for MAMAC Systems part number A-523, then verify the connected sensor, mounting arrangement, dimensions, and application. The A-523 measures approximately 4.5 by 2.75 by 0.75 inches, supports flush mounting or a standard 2-inch by 4-inch junction box, and is specifically documented for use with MAMAC PR-274 and PR-275 low-pressure sensors.
