Reliable level detection in hazardous areas

High resolution level measurement for sanitary applications WIKA ’s model FLM-Hmagnetostrictive level 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 clean- ing 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, ad- ditional 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 a 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 conforms, based on a third party verification, to the 3-A standard.

LMT sensors reliably detect levels in storage tanks in explosive areas. They can be used in zones 2 and 22. The sensor with its high-quality housing materials such as high-grade stainless steel (316L / 1.4404) and PEEK meets all requirements for hygienic areas.This includes approvals such as EHEDG and FDA. The LMT can be adjusted to almost all liquid and viscous media as well as powders. The distinction between two media in the same application is possible due to the two switching outputs which can be set independently. Convenient parameter setting is made via IO-Link. Applications for these sensors include liquids, viscous media and powders. Enquiries: Alwyn Skelton. Tel: +27 12 450 0400 or email info.za@ifm.com
