Description
The Johnson Controls Hx-68P3-0N000U outdoor humidity and temperature transmitter is designed for environmental monitoring and control systems that require stable and accurate measurement of relative humidity and temperature. It combines digital linearization and temperature compensation with thermoset polymer-based humidity sensing and NTC thermistor temperature sensing technologies.
Its weather-resistant polycarbonate enclosure includes a hinged, gasketed cover and an integrated sun and windshield for outdoor installation. The transmitter supports field-selectable analog outputs of 4 mA to 20 mA, 0 VDC to 5 VDC, or 0 VDC to 10 VDC and can provide humidity, dry-bulb temperature, dewpoint, wet-bulb temperature, or enthalpy measurements.
Frequently Asked Questions
Can the Hx-68P3-0N000U be installed outdoors?
Yes. Its IP65 (NEMA 4X) polycarbonate enclosure and integrated sun and windshield protect the sensors for exterior wall mounting.
What measurement variables does it output?
It measures relative humidity and dry-bulb temperature by default, and can output dewpoint, wet-bulb temperature, or enthalpy, selectable during installation.
How accurate is the humidity reading?
Relative humidity accuracy is ±2% RH between 10% and 90% RH at 25°C; temperature accuracy is ±0.4°F (±0.2°C).
