    CO2 from 0 to 2000/5000/10000 ppm or
    temperature from -200 to +600 °C using Pt1000 RTD temperature probe
  • Two inputs for measured value recording
  • Wall-mounted housing with backlit LCD display
  • Open air range 300 m

Customer benefits

  • Wiring expenses are eliminated with modern wireless technology


The Wtrans E01 measuring probe is used in combination with a Wtrans receiver for recording measured values using digital sensors for humidity, temperature, and CO2. The measuring probe has two inputs with plug connectors M12 × 1 to which the sensors can be connected and then detected in any combination (Plug and Play).
Other measurands can be derived from the determined measured values. A maximum of four measured values are acquired. They are transmitted to the receiver of the Wtrans measuring system, where they are displayed, at a radio frequency of 868.4 MHz. The values are available as digital or analog output variables. The voltage is supplied externally (DC 18 to 30 V) or internally by four lithium batteries (size AA). The battery operating life with the recommended type of battery is one year (with default settings and one sensor).
The electronics of the measuring probe with backlit LCD display and operating keys are encased in wall-mounted housing (protection type IP65). The ambient temperature range of the measuring probe is -30 to +80 °C, but the differing ambient temperatures of the sensors and lithium batteries must also be considered. The measuring probe can be configured using the USB interface or the operating keys.
