Veris Industries TFDKR00 Sensor

The Veris Industries TFDKR00 is an industrial-grade duct mount temperature sensor engineered for precise thermal monitoring within Building Automation Systems (BAS) and HVAC mechanical equipment rooms. This unit features an 8-inch stainless steel probe, providing the necessary reach for accurate mid-stream airflow measurements in large-diameter ductwork. At its core, the sensor utilizes a 10k Ohm Type 3 thermistor paired with an 11k Ohm shunt, delivering high-stability resistance output with a standard accuracy of ±0.2°C (±0.36°F). This specific element configuration ensures compatibility with legacy field controllers that require a shunted resistance curve for proper scaling.

Housed in a rugged galvanized steel junction box (handi-box style), the TFDKR00 is built to withstand the mechanical stresses of commercial mechanical rooms. The corrosion-resistant probe protects the sensing element from oxidation and contaminant buildup, maintaining signal integrity over time. Designed for easy installation, the duct temperature sensor mounts directly to the duct exterior and includes 22 AWG pigtail leads for rapid wiring termination. This sensor is optimized for non-condensing, indoor environments with an operating range spanning -13° to 221°F, making it a reliable choice for supply, return, and discharge air monitoring.

• Enhanced Compatibility: The 10k Type 3 thermistor with 11k shunt matches common controller input requirements for seamless integration.
• Industrial Durability: Features a stainless steel probe and a NEMA 1 galvanized steel enclosure to protect internal connections.
• High Precision: Pre-calibrated sensing element offers a narrow tolerance of ±0.2°C for tight environmental control.
• Simplified Mounting: Standard 8-inch probe length and integrated mounting box allow for quick installation on sheet metal ductwork.
• Wide Operating Range: Rated for temperatures between -13°F and 221°F, suitable for various HVACR applications.

Is the TFDKR00 suitable for high-humidity or outdoor applications?
No, this model is designed for indoor use in non-condensing environments. For outdoor or high-moisture areas, a sensor with a weatherproof (NEMA 3R or better) enclosure is recommended.

Why does my controller read a fixed high or low temperature?
A fixed "out of range" reading typically indicates an open circuit (infinite resistance) or a short circuit (zero resistance) in the sensor wiring or the 10k thermistor element. Verify all 22 AWG pigtail connections and check the resistance at the sensor leads using a multimeter.

Does this sensor require field calibration?
The TFDKR00 is factory-calibrated and designed for "plug-and-play" operation. Because the thermistor is a highly stable passive device, periodic recalibration is generally not required unless the BAS controller necessitates a specific offset.
