Outdoor Temperature Sensors

Metal

Plastic (RTD/Thermistor)

Plastic (0 to 10V/4 to 20 mA)

Description

Siemens Outdoor Temperature Sensors monitor and

transmit changes in temperature to the HVAC control

system. The sensor resistance varies proportionally to

the actual temperature being measured.

Units are offered in traditional metal housing as well

as modern and aesthetically pleasing polycarbonate

housings that blend into today’s architectural trends.

All are ruggedly designed and built for years of

weatherproof, outdoor service.

Multiple output signals are available to ensure

compatibility with most common HVAC control

systems.

Features

 Variety of sensing elements.

 Responsive to temperature changes.

 Accurate and reliable indication of temperature.

 Easy installation requires no special tools.
