The WIKA FLM-H magnetostrictive sensor has been specifically designed for the requirements of the food and beverage, pharmaceutical and biotechnology industries. The sensor is particularly suitable for the special conditions of CIP/SIP cleaning processes, such as chemical stability towards cleaning liquids and high temperatures. The guide tube is directly welded to the process connection, which guarantees a crevice-free connection, additional sealings are not required. The sensor is supplied with a DC voltage of 10 … 30 V. Available output signals are 4 … 20 mA or 4 … 20 mA with HART® signal. The hygienically designed sensor housing, with an ingress protection of up to IP 68, offers secure protection for external cleaning with splash water and enables its use in high-humidity environments. The model FLM-H sensor fulfils the high demands of sanitary applications. It is marked with the 3-A symbol and current version number, as it confirms, based on a third-party verification, to the 3-A standard.

The WIKA TR21-A resistance thermometer provides temperature measurement in sanitary applications and can be used for the measurement of liquid and gaseous media in the range of -30 … +250 °C (-22 … +482 °F). For application in hazardous areas, intrinsically safe versions are available. These thermometers are fitted with thermowells, whose process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring points. All electrical components are protected against moisture (IP67 or IP69K). The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the PC configuration software WIKAsoft-TT. Measuring range, damping, error signalling per NAMUR NE43 and TAG no. can be adjusted. For easy calibration or maintenance, the sensor is removable without having to break into the process or disconnect the electrical connection. Thus hygiene risks can be minimised, and downtimes can be reduced. The spring loading, integrated into the union nut, guarantees the contact between the sensor tip and the bottom of the thermowell and thus ensures a short response time and lasting high accuracy. The welded junction between the thermowell and the flange makes the use of a sealing as additional material in those areas redundant which are in contact with the product. Insertion length, process connection, sensor and connection method can each be selected for the respective application within the order information. The electrical connection is made via an M12 x 1 circular connector. For applications requiring the sterilisation of the instrument in autoclaves, an especially temperature-resistant instrument version is available.
