HE-69520NP-0 Johnson Controls Humidity Element

Overview

The Johnson Controls HE-69520NP-0 is a duct-mounted relative humidity and temperature sensor designed for precise environmental monitoring in commercial HVAC and building automation systems (BAS). Housed in an all-plastic plenum-rated enclosure, it combines humidity and temperature sensing elements inside a single duct probe to simplify installation and optimize indoor air quality.

Features

• Combined relative humidity and temperature monitoring in one duct probe
• Accurately measures relative humidity with a +/-2% RH accuracy rating
• Employs a premium Pt1000 Class A Platinum RTD temperature sensing element
• Features a durable all-plastic housing optimized for duct-probe thermal performance
• Simplifies multi-system integrations with a user-selectable output voltage range

Specifications

• Humidity Accuracy: +/-2% RH
• Temperature Sensor Type: 1k Ohm Platinum RTD (Class A)
• Humidity Output Signal: Proportional 0-10 VDC
• Input Power Requirements: 14 VDC to 30 VDC or 20 VAC to 30 VAC (50/60 Hz)
• Probe Length: 6.25 inches
• Enclosure Rating: Plenum rated (UL 2043), UL flammability compliant

Applications

• Commercial office buildings and institutional HVAC monitoring
• Direct-mount integration with building automation systems and controllers
• Return, supply, or exhaust air duct monitoring in handling units
• Economizer control and indoor air quality (IAQ) tracking strategies
