Reznor 206081 Sensor

The Reznor 206081 Duct Humidity Sensor is a precision HVAC relative humidity transmitter engineered for seamless integration into commercial and industrial air handling systems. As an OEM-specified component, this duct mount humidity sensor is identical to the HE-67N3-0N0GS and serves as a direct upgrade for legacy HE-6320 series elements. Built with an all-polymer capacitive humidity element, it offers superior resistance to chemical corrosion while maintaining a 0 to 5 VDC output proportional to 0-100% RH. This unit also features an integrated 1k ohm thin film nickel temperature sensor, allowing for simultaneous monitoring of duct conditions via a single probe location.

Operating on a 14-30 VDC or 20-30 VAC Class 2 power supply, the HE-67N3-0N0GS duct sensor provides ±3% RH accuracy across the 20-80% range. The 3-wire humidity transmitter configuration uses standard 1/4 inch male spade terminals, simplifying field replacement in Reznor rooftop units and economizers. With a durable plastic enclosure and a survival range of -20 to 140°F, this Johnson Controls humidity element is the professional standard for maintaining precise psychrometric control in demanding environments.

• Dual-Function Sensing: Measures both relative humidity and temperature (1000 Ohm Nickel) through a single duct penetration.
• Corrosion Resistance: All-polymer construction protects internal circuitry against high-moisture HVAC environments.
• OEM Compatibility: Exact replacement for Reznor 206081 and HE-67N3-0N0GS ensures zero-modification installation.
• Wide Input Range: Versatile 24V AC/DC power requirements accommodate most standard building automation controllers.
• High Precision: Reliable ±3% RH accuracy prevents short-cycling of humidification and dehumidification equipment.

Is the Reznor 206081 a direct swap for the Johnson Controls HE-67N3-0N0GS?
Yes, these parts are identical. The 206081 is the Reznor-labeled version of the same high-performance humidity element produced by Johnson Controls.

What type of wiring is recommended for this sensor?
For optimal signal integrity, 18 AWG shielded twisted-pair wire is recommended, though the terminals accept 16 to 24 AWG leads.

Can this sensor be used in high-temperature discharge air applications?
The sensor is rated for ambient operating conditions up to 140°F (60°C). Exceeding these limits may impact sensor accuracy or lead to component failure.
