This hygienic level sensor is FDA compliant
The capacitive sensor KA1590 (photo) from the 26 Series now has IO Link Technology. This IO Link sensor can detect products with a dielectric constant as low as 1.1. The sensor comes with normally open contact and normally closed contact. On and off delay-timing functions are programmable for the application requirements. The sensor operates on 10–35 V d.c., the housing is IP67 sealed for cleaning in place and installation is quick with tri-clamp mounting. The polytetrafluoroethylene (PTFE) housing is FDA 21 CFR 177.1550 compliant for use in food and pharmaceutical applications. The sensor has a temperature rating up to 100°C. Applications include level control for batching of paste-type products, liquids and bulk solids and powders used in food and pharmaceutical manufacturing. — Rechner Electronics Ind.
