The SICK THTL Series Temperature Sensor is an in-line thermometer designed for hygienic temperature measurement
in pipes. Typical applications include food and beverage, pharmaceutical, cosmetics and biotechnology industries. The THTL features an in-line housing that is fitted into the pipe, with a Pt100 sensor located inside a thermowell that is placed in the medium flow. This can be easily replaced, ensuring safe hygienic operation. The THTL Series wetted parts are made from corrosion-resistant stainless steel, making it suitable suited for CIP and SIP processes. In addition to a direct electrical connection to the Pt100 element, the THTL is available with an integrated transmitter with 4 to 20mA output.
