DwyerOmega EWSA Series Air Temperature Sensor
The DwyerOmega EWSA Series Air Temperature Sensor features a ventilated housing for accurate airflow measurement, rugged NEMA 4X (IP65) enclosure, and a choice of Pt100 RTD or 4-20 mA transmitter for demanding environments.
The DwyerOmega EWSA Series Air Temperature Sensor offers a rugged solution for outdoor and demanding environment temperature monitoring. A 6 mm sheathed RTD probe sits within a 12.7 mm ventilated outer tube for improved airflow and accurate readings. The aluminum alloy enclosure is NEMA 4X (IP65) rated for weather resistance and durability. Models include a Pt100 Class A 4-wire RTD or a version with a built-in 4-20 mA transmitter for loop-powered output. A screw terminal block ensures secure connections, while the M20 cable gland accepts 2.5–6.5 mm OD cables. Ideal for industrial sites, environmental monitoring, and HVAC applications, this air temperature sensor combines reliability with easy installation. Available now from Hinco, Perth, WA.
