UT051 Outside temperature sensor

Outside temperature sensor

Wall-mounted, dimensions 90 x 107 x 26 mm,
-20...70 °C, IP 43
Measuring element Pt1000


Temperature sensor UT051 is a passive Pt1000 sensor in plastic housing for measuring of outside temperature or temperature in industrial environment.

  • Air handling units, heating systems – temperature measurement and control
  • monitoring and outside temperature measuring

Sensing elements change their electric resistance with temperature. The measuring element is a thin-layer platinum resistor: on a ceramic base there is a thin layer of pure platinum. This layer is structured by photolithography and calibrated with laser beam to achieve its nominal value.  The active layer is passivated by a glass layer which prevents the platinum film from mechanical and chemical damage. The outputs are welded to the active layer. The element is installed on a PCB with terminals, which is fixed to the inside of the housing. After the sensor is installed, the top snaps on the bottom and the pins connect the element with the cabled terminals. 

The sensors are intended for operating in a normal and chemically non-aggressive environment. They do not need any servicing or maintenance. They should be installed vertically to keep the protection degree. The sensor consists of two parts: bottom with terminals and top with the printed circuit board and measuring element. The sensors are mounted with 2 or 4 screws on a flush-mounted junction box with 5 mm in diameter or on any flat surface. In the bottom there is a hole to bring the cable in.
