The Veris AA06 is a dry pressure sensor pickup tube in a durable all-metal construction. It’s designed for duct static pressure applications and plant room measurement, offering robust performance in environments where moisture and contamination could affect sensors. This accessory is best paired with compatible measurement instruments to monitor static pressure accurately.
Who it’s best for: facilities and installers seeking a rugged pickup tube as part of a static pressure sensing setup. Why chosen: all-metal construction enhances durability in challenging environments. Limitation: you’ll need compatible sensing equipment for full utilization.
Buying Guide
What type of duct static pressure sensor do you need?
– For simple on/off control of a duct fan, consider a plug-in or wired activation switch that responds to blower activity.
– For precise diagnostic work, use a multi-probe or wireless manometer system that can measure multiple points and provide total external static pressure.
What outputs matter for your control system?
– Analog signals (4–20 mA, 0–10 V) suit PLCs and DCS, while digital interfaces (RS485) enable smart integration with building automation.
– If you need wireless data collection and real-time charts, prioritize portable or battery-powered devices with a robust range.
How important is durability and environment?
– All-metal pickup tubes and sealed sensors handle tougher environments, reducing the risk of damage from dust or moisture.
What installation considerations apply?
– Plug-in switches offer quick setup, while wired switches require electrical work but can be less invasive in some installations.
How should you verify compatibility?
– Confirm that sensor models match the target duct size, pressure range, and required output signals for your control system. Check for compatibility with existing HVAC equipment and measurement instruments.
FAQ
- What is a duct static pressure sensor used for?
It measures the pressure difference inside ducts to help balance airflow and ensure HVAC efficiency.
- Can these sensors integrate with building automation systems?
Yes, many offer outputs like 4–20 mA, 0–10 V, or RS485 for direct PLC or DCS integration.
- Is a wireless manometer better than a traditional hose-based setup?
Wireless systems reduce hose clutter and allow measurements from remote or hard-to-reach spots, improving workflow.
- Are all-metal pickup tubes necessary?
No, but they are preferred in harsh environments where durability matters.
- How do I choose between a plug-in switch and a wired activation switch?
Choose plug-in for easy installation; choose wired if a hard-wired, integrated control is required.
