Honeywell C7046A1038 Temperature Sensor

The Honeywell C7046A1038 is a professional-grade discharge air temperature sensor engineered for precise thermal monitoring in commercial HVAC systems. Featuring a 12-inch insertion length, this probe-style sensor is optimized for duct air temperature sensing where accurate readings of supply or return air are critical for system balance. The unit utilizes a 3K ohm NTC thermistor at 77?F, ensuring compatibility with a wide range of electronic controllers and building automation systems. Built for durability in high-airflow environments, it operates within a 40?F to 150?F range, making it ideal for HVAC discharge air monitoring. The sensor is designed for versatile field installation; it can be mounted directly to a flat duct or plenum surface using its integral flange, or housed within a standard 2x4 inch junction box. Whether utilized as a primary control sensor or a secondary limit, the C7046A1038 provides the rapid response time necessary for efficient economizer control and air handling unit performance.

• Precise 3K Ohm NTC Element: Delivers accurate resistance-to-temperature conversion for reliable signal input to controllers.
• 12" Probe Depth: Allows for deep insertion into large ducts to capture a representative average of the air stream.
• Rugged Mounting Options: Includes an integral flange for direct surface mounting or integration into a 2x4 junction box for code compliance.
• Broad Application Range: Rated for temperatures up to 150?F, suitable for both heating and cooling discharge monitoring.

Is the C7046A1038 compatible with non-Honeywell controllers?
Yes, provided the controller is calibrated for a 3K ohm NTC (Negative Temperature Coefficient) thermistor curve at 77?F (25?C).

Can this sensor be used for water temperature sensing?
No, this model is specifically engineered for air temperature applications; immersion in liquid will damage the thermistor element.

What is the proper mounting position for the probe?
For the most accurate discharge air temperature sensor readings, mount the probe downstream from the coils or dampers in a location that represents the average air temperature, avoiding dead spots or laminar flow at duct corners.
