Power & Energy Meter Solutions
This outdoor air temperature transmitter and RTD provides accurate ambient temperature measurements and is housed in a NEMA 4 plastic (IP65) enclosure. It uses a platinum RTD with a nominal resistance of 1 kΩ.
This outdoor air temperature transmitter and RTD provides accurate ambient temperature measurements and is housed in a NEMA 4 plastic (IP65) enclosure. It uses a platinum RTD with a nominal resistance of 1 kΩ.
The AcuTEMS OA series sensor measures outdoor ambient air temperature with up to ±0.36°F (±0.2°C) accuracy. Designed to be mounted on a vertical surface outdoors in a shaded location, the sensor comes with an IP65 enclosure for protection against outdoor elements. The AcuTEMS OA features multiple RTD, thermistor, and transmitter output options, and it is ideal for HVAC/R systems to maintain comfort and ensure efficient equipment operation. For applications under direct sunlight, install the AcuHUM OAW instead, which comes with a sixlayered weather shield for extra UV protection, boosted ventilation and improved accuracy.

How to choose an Outside Air Temperature Sensor?
How to choose an Outside Air Temperature Sensor?
Outside air temperature sensor designed to measure ambient air temperature outside buildings and facilities using precision sensing elements, including 100Ω Platinum, 1kΩ Platinum, Nickel RTDs, and 10kΩ Type II, Type III, or 20KΩ thermistors. The sensor is installed vertically in a shaded outside location using screw mounting and push-button wiring. An IP65-rated enclosure protects against dust, moisture, and other outdoor elements. With a response time under 10 seconds, the sensor transmits temperature data to building automation system controllers to support efficient operation of economizers, heating, and cooling systems, ensuring optimal indoor comfort and reliable HVAC/R performance.
