Overview

The KFK03 measures air temperature and other gaseous media in supply and exhaust ducts, up to +250 °C. It is fixed with a mounting flange. Fitted in a thermowell it can also be used as an immersion sensor. It has an 8 mm stainless steel probe in four lengths, 100, 150, 200 and 250 mm, in an IP66 aluminium housing. The output is 0 to 10 V on the TRV types and 4 to 20 mA on the TRA types, each in five temperature ranges.
