Stainless-steel stick-in sensor (B form), Pt100, thermocouple, integrated measuring amplifier
Temperature sensors of type T.4.-3 are stainless-steel stick-in sensors (form B connection head) for protection tubes and are available with a Pt100 measuring element or a thermocouple. The sensors are also available with two Pt100 or two thermal measuring elements with 2-wire technology; the Pt100 measuring element is available with 4-wire technology too. They have a 90° cable outlet at the side and are fitted in protection tubes.
