About Seli
Seli GmbH Automatisierungstechnik has been active as a systems house for automation technology since 1990 and has also established itself as a manufacturer of intelligent measuring technology in Hygienic Design. At its own facility in Neuenkirchen, the company with more than 30 employees develops and manufactures hygienic temperature sensors, pressure transmitters, level limit switches, conductive level probes, TDR level gauges and analysis instrumentation for turbidity and conductivity, complemented by evaluation electronics and signal transmitters. Media-contacting parts are made predominantly of stainless steel (including 1.4305, 1.4404, 1.4571, 1.4435), PEEK and PTFE; all products are designed to be EHEDG-compliant and FDA-compliant. Around 80 % of projects are in the food industry, with further customers from breweries, dairies and the beverage industry. In addition to development and manufacturing, Seli offers project engineering, installation and commissioning, recalibration in its own calibration laboratory, on-site service as well as seminars and training courses. Worldwide sales partners support delivery and after-sales service internationally as well.
