HE-69130NP-0 Johnson Controls Humidity Element

Overview

The Johnson Controls HE-69130NP-0 is a duct-mounted humidity and temperature sensor designed to combine both relative humidity (RH) and temperature sensing within a single all-plastic enclosure for use inside ducts. It is engineered to integrate seamlessly with HVAC control and building automation systems to ensure accurate environmental monitoring.

Features

• Combines humidity and temperature sensing in a single, compact unit
• Enclosed in durable all-plastic material that improves thermal performance and complies with UL flammability ratings for plenum use
• Equipped with a 6.25-inch duct probe for efficient installation and operation
• User-selectable output voltage range allows compatibility with both existing and new systems

Specifications

• Relative Humidity Accuracy: ±3% RH
• Temperature Sensor Type: Thin film nickel RTD (1K ohm at 70°F)
• Output Signal: 0 to 10 VDC proportional for humidity indication
• Power Requirements: 14 to 30 VDC or 20 to 30 VAC at 50/60 Hz
• Operating Humidity Range: 0% to 100% RH
• Operating Temperature Range: -20°F to 140°F (-29°C to 60°C)

Applications

• Monitoring and controlling duct humidity and temperature levels in commercial HVAC systems
• Calculating precise enthalpy to determine energy-efficient and cost-effective economization strategies
• Managing indoor air quality by monitoring and comparing duct humidity with levels advised in ASHRAE ventilation standards
