From the manufacturer's datasheet for SFK02+ FR active.
Overview
The SFK02+ FR is an immersion sensor with an integrated thermowell and a 4 mm tip for quick response. It measures liquids and gases in HVAC work and screws into a G1/2 inch fitting. Probe lengths are 50, 100 and 200 mm. Output is 0 to 10 V (TRV) or 4 to 20 mA (TRA) over a selectable range up to -50 to +250 °C scaling. Relay versions add two floating contacts for 2-point or 2-stage control, and LCD versions add a colour changing display with a traffic light function.
