Honeywell C7046A1004 Temperature Sensor

The Honeywell C7046A1004 is a professional-grade discharge air temperature sensor designed for integration into complex electronic control systems. Featuring a 3K Ohm @ 77?F NTC (Negative Temperature Coefficient) thermistor, this sensor provides precise, fast-reacting thermal feedback across an operating temperature range of 40?F to 150?F. Its 8-inch insertion length and rugged aluminum probe ensure accurate deep-duct sensing, critical for stabilizing system logic in both single-zone and multizone applications.

Engineered for versatility, the C7046A1004 functions reliably as either a primary or secondary sensor. The solid-state internal components are shielded from common environmental contaminants like dust and dirt, maintaining signal integrity over time. Installation is streamlined for the field: the unit features an integral flange for flat duct or plenum mounting and is fully compatible with standard 2x4 inch junction boxes. This sensor requires no calibration or settings, allowing for immediate deployment with Honeywell Excel controllers, W973, W7210, and T775 series 2000 systems.

• High-Accuracy Sensing: 3K Ohm NTC sensor element ensures precise control for HVAC discharge air monitoring.
• Durable Construction: The 8-inch aluminum probe is built to withstand high-velocity airflow and industrial environments.
• Streamlined Mounting: Flexible installation options via integral mounting flange or standard electrical junction box.
• Wide Compatibility: Seamlessly integrates with Honeywell building automation controllers and electronic logic panels.
• Low Maintenance: Solid-state design with no moving parts or field-calibration requirements reduces service callbacks.

What is the resistance curve for the C7046A1004?
This model utilizes a 3,000 Ohm thermistor at a reference temperature of 77?F (25?C). As an NTC sensor, the resistance decreases as the sensed air temperature rises, providing the specific signal required by many Honeywell legacy and modern electronic controllers.

Can this sensor be used for outdoor air applications?
While durable, the C7046A1004 is specifically designed as a duct-mounted discharge air sensor. For outdoor applications, ensure the housing is protected from direct moisture and within the specified 40?F to 150?F operating range.

Is this sensor compatible with non-Honeywell systems?
Yes, provided the controller is designed to accept a 3K NTC temperature input. Always verify the input resistance requirements of your specific logic panel before installation.
