Veris Industries TAJI0 Duct Sensor

The Veris Industries TAJI0 is a commercial-grade averaging duct sensor engineered for precise temperature monitoring in large air handling units (AHUs) and complex ductwork. Featuring a 24-foot flexible copper probe, this sensor utilizes a 1k Ohm Balco RTD (Nickel-Iron) element to provide a highly accurate averaged resistive output, effectively mitigating the reading errors caused by thermal stratification downstream of heating and cooling coils. Housed in a durable galvanized steel enclosure (Handy Box style), the TAJI0 is designed for direct duct mount applications, ensuring seamless integration with existing building automation systems (BAS). The 22 AWG pigtail terminations allow for straightforward field wiring, while the 3/16" diameter probe maintains structural integrity across its 24-foot span. For contractors troubleshooting temperature gradients in large plant rooms or chiller plants, this nickel-iron RTD sensor delivers the stability and linear response required for tight environmental control and optimized mechanical equipment performance.

Key Benefits

• Thermal Stratification Mitigation: The 24-foot sensing length eliminates "hot spots" by averaging the temperature across the entire duct cross-section.
• High Stability RTD: The 1k Ohm Balco element provides a positive temperature coefficient (PTC) for reliable long-term accuracy without significant drift.
• Durable Construction: Features flexible copper tubing and a NEMA 1 galvanized steel junction box for protection in mechanical room environments.
• Extended Measurement Range: Rated for operation between -13°F to 221°F, making it suitable for both heating and cooling stages.
• Ease of Installation: Designed for surface mounting with standard electrical knockouts for conduit connections.

Common Questions

• How do I prevent the probe from kinking during installation? For optimal performance, maintain a minimum bend radius of 50mm and use mounting clips to support the 24-foot copper capillary at regular intervals.
• Is the TAJI0 compatible with my BAS? This sensor provides a standard 1k Balco resistive output; verify that your controller's input points are configured for this specific RTD curve.
• Can this be used in high-moisture air streams? The TAJI0 is intended for indoor duct applications; ensure it is installed downstream of eliminator plates if air washers are utilized to prevent capillary corrosion.
