Johnson Controls HE-69130NP-0 Duct Probe Humidity & Temperature Sensor

HE-69130NP-0 Johnson Controls Duct Probe

The HE-69130NP-0 Johnson Controls duct probe is adept at measuring both relative humidity (RH) and temperature within air ducts. Ensuring high accuracy with a ±3% RH precision and a 0-10 VDC output signal, this sensor is encased in a robust NEMA 4X enclosure, shielding it from dust, moisture, and corrosion. Operating on a 24 VAC/VDC power supply, the sensor is tailored for duct mounting and employs a capacitive humidity sensor paired with a nickel RTD temperature sensor. A 6-foot (1.8 m) cable extends flexibility. With applications spanning HVAC and building automation to data centers, industrial facilities, and greenhouses, its benefits include precise climate control, resilient construction, seamless integration, and adaptability for diverse applications requiring accurate duct airflow measurement.

Key features:

• 3% RH Accuracy: This sensor provides reliable humidity readings within a ±3% margin, ensuring precise control over air quality in various environments.
• Rugged NEMA 4X Enclosure: Housed in a durable NEMA 4X enclosure, the sensor is resistant to dust, moisture, and corrosion, making it suitable for harsh industrial and outdoor environments.
• Duct Probe Design: The convenient duct probe design allows for easy installation and positioning within air ducts, ensuring accurate measurements of air conditions within the HVAC system.
• Wide Operating Temperature Range: The HE-69130NP-0 functions effectively in a wide temperature range of -40°F to 158°F (-40°C to 70°C), making it suitable for diverse climate conditions.

Sings of faulty Johnson Controls Duct Probe

Following are the faulty signs to look for:

• Erratic humidity readings and inconsistent temperature measurements may indicate a malfunction in the Johnson Controls Duct Probe.
• Unusual fluctuations in the 0-10 VDC output signal could be a sign of a faulty sensor.
• A decline in the overall accuracy of relative humidity (RH) readings beyond ±3% may suggest a malfunctioning duct probe.
• Physical damage or corrosion on the NEMA 4X enclosure may compromise the sensor's performance.
• Failure to respond to a 24 VAC/VDC power supply could be indicative of a power-related issue.
• Inability to maintain stable readings in diverse applications, such as HVAC systems or industrial facilities, may signal a malfunction in the duct probe.
