THTL

Overview

Perfect fit: Hygienic temperature measurement in pipes

Designed as an in-line thermometer, the THTL temperature sensor is the preferred solution for hygienic temperature measurement in pipes. Typical applications are in the food and beverage, pharmaceutical, cosmetics and biotechnology industries. The THTL has an in-line housing that is fitted into the pipe. The Pt100 sensor is located inside a thermowell that is placed in the medium flow. It can easily and quickly be replaced for maintenance or calibration. This ensures safe hygienic operation.

The design of the wetted parts made from corrosion-resistant stainless steel complies with hygienic standards and enables quick response times.

The THTL is well suited for CIP and SIP processes. This enables safe hygienic operation in conjunction with optimized equipment availability.

Besides its direct electrical connection to the Pt100 element, the THTL is available with an integrated transmitter with 4 mA ... 20 mA output signal.
