Temperature sensors
Temperature sensors and transmitters convert the temperature of a liquid, gas or surface into a standard signal. DWIN supplies general-purpose temperature transmitters, probes for heat pumps and HVAC, and battery-powered wireless temperature and humidity sensors.

How it works
A platinum resistance element (such as a Pt100 or Pt1000) or an NTC thermistor changes resistance with temperature. The transmitter linearises and compensates that change and outputs it as 4 to 20 mA, a voltage, RS485 or a wireless message.
How to choose
- Sensing element and range: Pt100, Pt1000 or NTC
- Probe length, diameter and process connection
- Output: 4 to 20 mA, RS485, or Bluetooth and other wireless links
- Response time and ingress protection for the medium
Frequently asked questions
Pt100 or NTC temperature sensor?
A Pt100 is linear, interchangeable and accurate over a wide range, which suits industrial measurement. An NTC thermistor is cheaper and more sensitive over a narrow range, which suits HVAC and appliances.
