Tjernlund PS1503P Plug-in Air Pressure Activation Switch
The PS1503P is an air pressure activation switch that turns duct fans on and off based on the furnace or blower status. Best for single-zone residential systems and simple duct fan control where automatic switching is desired. It works with any brand duct fan, including Tjernlund Duct Booster Fans, and offers plug-in and simple wiring options. Limitations include a potential need for proper wiring conventions to ensure compatibility with existing controls. Choose this if you want a straightforward, plug-in solution with dependable switching behavior.
Tjernlund PS1503 Pressure Activation Switch
This is another Tjernlund activation model focused on duct fan control. Best for buyers seeking a dedicated HVAC control switch with straightforward installation. It’s suitable for controlling fans in central heating and air conditioning systems. A potential limitation is that installation may require some wiring expertise to integrate with existing control networks.
Static Pressure Probes FATCANMA (2-Pack)
These static pressure probes are designed for measurement in HVAC systems and are compatible with common manometers like Fieldpiece AMIN2/ADMN2/SDMN5. Best for technicians who want greater accuracy and flexibility than a single-tube setup. The two-pack configuration provides redundancy and steady readings from multiple points. A limitation is that proper magnet flange alignment is required for stable measurements in some ducts.
AXIOASRKIX Air Duct Static Pressure Sensor YZ1301
The YZ1301 offers a versatile output suite, including 4–20 mA, 0–10 V, and RS485, enabling direct integration with PLCs and control systems. Best for plants or facilities needing signal versatility and digital compatibility. The one-button zero/span calibration and self-diagnostics simplify setup and ongoing monitoring. A potential drawback is reliance on compatible interfaces in the control system for full benefit.
Fieldpiece JL3KM2 Job Link System
The JL3KM2 is a long-range, wireless dual-port manometer kit. Best for HVACR professionals who need readings from remote or hard-to-reach locations. It supports up to eight simultaneous readings and offers a switchable P1–P2 indicator for accuracy. This kit excels in complex systems but requires compatible Fieldpiece components for full functionality. Consider if you need wireless flexibility and multi-point data capture.
Veris AA06 4 Inch Pickup Tube
The Veris AA06 is a four-inch pickup tube made from all-metal construction and designed as a dry pressure sensor accessory for duct static pressure and plant room applications. Best for installations requiring a robust, compact pickup for static pressure sampling. A potential limitation is compatibility with broader sensor systems; ensure the pickup tube interfaces correctly with your measurement hardware.
Buying Guide: Key Considerations For Duct Static Pressure Sensors
- Measurement purpose: Do you need a simple on/off activation switch, a precise differential pressure probe, or a full-featured transmitter with multiple outputs?
- Output compatibility: Look for devices offering 4–20 mA, 0–10 V, or RS485 to match your control system, PLC, or data logger.
- Installation environment: Consider duct size, metal vs. plastic ductwork, and access for sensors or probes.
- Wiring and power: Evaluate whether a plug-in model suits your setup or if hard-wired connections are required.
- Flexibility and range: For professional HVAC work, wireless or multi-point capabilities can save time and improve accuracy.
- Durability and materials: All-metal pickup tubes and rugged probes are preferable in industrial settings, while residential use may tolerate lighter builds.
