From the manufacturer's datasheet for SFK02+ active.
Overview
The SFK02+ is an immersion sensor for measuring the temperature of gases and liquids in HVAC systems. It can be screwed into a bonded pocket (available as an accessory), and the measuring insert can be changed without removing the whole sensor. The SFKH02+ type with a 70 mm neck pipe is for insulated installations. The output range is selectable from several presets. Versions have a 0 to 10 V or 0 to 5 V output, a 4 to 20 mA output, or a voltage output plus a relay for 2 point or 2 stage 2 point control. LCD versions show the value with a traffic light function.
