Series-TE-AConfiguration

Supported Applications

The Series TE Duct and Immersion Building Automation Temperature Sensors are designed to monitor air or water temperature throughout a building management system or an air handler unit. The series supports duct mount configurations for airflow monitoring as well as immersion probe applications.

Operating Conditions & Performance

Sensors operate within a temperature range of -40 to 302°F (-40 to 150°C). Accuracy specifications vary by sensor type: the thermistor temperature sensor provides ±0.22°C @ 25°C (±0.4°F @ 77°F), while the RTD temperature sensor meets DIN class A standards at ±0.15°C @ 0°C (±0.28°F @ 32°F). The housing material for applicable models is UL 94 V-0 polycarbonate plastic, and specific configurations carry a NEMA 4X (IP66) rating.

Key Performance Specifications

• Operating Temperature: -40 to 302°F (-40 to 150°C)
• Thermistor Accuracy: ±0.22°C @ 25°C (±0.4°F @ 77°F)
• RTD Accuracy: DIN class A: ±0.15°C @ 0°C (±0.28°F @ 32°F)
• Housing Rating: NEMA 4X (IP66) for DFW and IBW configurations only
• Compliance: Meets the technical requirements of EU Directive 2011/65/EU (RoHS II)

Configuration Options

The Series TE offers a configurable model structure defined by mounting configuration, sensor type, probe length, diameter, termination style, and fittings. The series supports both thermistor and RTD output signals.

Mounting Configurations

• Duct Mount: Probe only (DFN), general purpose housing (DFG), or NEMA 4X housing (DFW)
• Immersion: Probe only (IBN), general purpose housing (IBG), or NEMA 4X housing (IBW)

Sensor Types & Elements

• 10k Ω type III thermistor
• 10k Ω type II thermistor
• 3k Ω thermistor
• Pt100 Ω RTD
• Pt1000 Ω RTD
• 20k Ω thermistor
• 10k Ω type III with 11k Ω shunt

Mechanical & Termination Options

• Probe Lengths: Available in 2.5", 4", 6", 8", 12", and 18" (DFN/DFG only)
• Probe Diameter: 1/4" for DFN/DFG configurations; 1/4" double encapsulated
• Terminations: Includes 4" leads with spade connectors, 4" leads, or an 8' plenum rated cable option (with or without spade connectors)
• Fittings: None (probe only), 1/2" NPT compression fitting, or 1/4" NPT compression fitting
• Housing Features: Includes a terminal connector to eliminate the need for wire nuts and multiple conduit knockouts. Duct models feature external tab housing options.

Key Product Differences

Variants within the Series TE are distinguished by their mounting environment (duct versus immersion) and enclosure protection level. The model number guide follows the format: TE - [Mounting Configuration] - [Sensor Type] - [Probe Length] - [Probe Diameter] - [Termination] - [Fittings]. For example, TE-DFN-A0448-00 represents a duct mount probe only with a 10k Ω type III thermistor. The NEMA 4X (IP66) enclosure rating is specific to the DFW and IBW configurations; other housing styles do not carry this rating in the provided documentation.
