Pipe surface Temperature Sensors (ET741)
ET741 series pipe surface temperature sensors are designed for measuring temperatures of hot water pipes in HVAC applications.
ET244
ET244 surface temperature sensor is designed for measuring temperature on flat or slightly curved surfaces. The sensing element is encapsulated in a flexible protection cap made of silicone rubber. The sensor is fixed on the surface with adhesive acrylic film.
