Johnson Controls TE-6351M-1 Temperature Sensor

The Johnson Controls TE-6351M-1 is a professional-grade duct mount temperature sensor designed for precise environmental monitoring within Building Automation Systems (BAS) and Direct Digital Control (DDC) environments. This model features a high-accuracy 1k ohm Platinum RTD (Resistance Temperature Detector) sensing element, ensuring stable and repeatable measurements across an operating range of -50 to 220?F. The 8-inch probe is constructed from durable stainless steel to provide superior corrosion resistance and thermal response, making it suitable for high-velocity air streams and varied duct environments. Housed in a handy box metal enclosure, the unit meets UL 1995 plenum requirements, allowing for safe installation in ceiling spaces and air handling units. The TE-6351M-1 simplifies field deployment with a design that includes a pre-installed conduit box and includes hex-head self-drilling screws for immediate mounting to galvanized ductwork. Contractors and service tech professionals rely on this sensor for its NEMA 1 rating and seamless integration into Johnson Controls Metasys or any third-party control architecture requiring a standard 1k ohm platinum signal.

• Platinum RTD Precision: The 1k ohm thin-film platinum element offers higher accuracy and lower drift than standard thermistors over time.
• Plenum Rated Enclosure: The galvanized steel metal box satisfies strict fire and smoke safety codes for installation in plenum spaces.
• Extended Probe Reach: An 8" probe length ensures the sensing element is positioned in the center of the air stream for an accurate average temperature reading.
• Direct BAS Integration: Compatible with any controller accepting a 1k ohm platinum resistance input, facilitating easy retrofits and new installations.
• Rugged Construction: Built to withstand commercial HVAC environments with a focus on long-term vibration resistance and environmental protection.

• How do I minimize wiring-induced temperature errors? Lead wire resistance can affect accuracy; for this platinum RTD sensor, keep runs short and limit total wiring resistance to under 2 ohms to maintain calibration.
• Can this be used in moisture-heavy applications? While the probe is stainless steel, if condensation is expected, the unit should be mounted at an angle to allow moisture to drain away from the conduit box.
• Is a separate mounting flange required? No, the TE-6351M-1 features an integrated mounting plate on the steel enclosure for direct-to-duct attachment.
