Description

The CS Instruments FA 515 Ex Dew Point Sensor sets the standard for moisture monitoring in industries where explosive atmospheres are a constant concern. Managing dew point is critical to preventing corrosion, system blockages, and quality issues, but doing so in hazardous zones requires specialized instrumentation.

This sensor is built to deliver continuous, accurate data across various non-aggressive media, including Hydrogen, Natural Gas, and Biogas. Its design prioritizes “Intrinsic Safety,” ensuring that the electrical energy available in the output circuit is always low enough that ignition of the explosive atmosphere cannot occur.

To maintain its intrinsically safe rating, the FA 515 Ex is designed to be operated in conjunction with approved transmitter power supplies, safety barriers, or galvanic isolating elements. Whether you are monitoring compressed air lines in chemical plants or managing gas quality in energy production, this sensor provides the reliability and safety certification required for modern industrial compliance.

CS Instruments

CS Instruments GmbH & Co. KG with locations in 24955 Harrislee and 78052 Villingen-Schwenningen/ Tannheim, is managed by Dipl. Eng. (FH) Wolfgang Blessing as sole Managing Director.

CS Instruments GmbH was established in the year 2002 by Christian Schuldt and Wolfgang Blessing as equal shareholders/Managing Directors.

Wolfgang Blessing already was sound a specialist on the sector of compressed air technology resp. industrial measurement technology long before the establishment of CS Instruments GmbH in the year 2002. Prior to the foundation of CS Instruments GmbH Dipl. Ing. (FH) Wolfgang Blessing acted for more than 10 years as primarily responsible product manager for industrial measurement technology at a worldwide known manufacturer of measuring instruments for compressed air and gases in the Black Forest. The technical knowledge and experience matched with the long-term practical knowledge was the corner stone for the success of CS Instruments.
