CS Instruments FA 510/515 Dew Point Sensor For Adsorption Dryers

Description

In addition to the previously common 4…20 mA analogue output the new generation of dew point sensors have a digital RS 485 interface (Modbus-RTU). All values like e. g. dew point, temperature, absolute humidity … which are measured and calculated by the dew point sensor can be retrieved via the Modbus protocol.

Compared with the previous models the sensorics and evaluation electronics have been improved once again, especially the integrated temperature compensation. This means: Increased accuracy at different ambient temperatures and an improved resolution of the sensor signal. Like the previous models the new dew point sensors have an excellent long-term stability and show reliable measured values. The sensor element is insensitive against condensation and due to the serial sintered cap made of stainless steel it is protected against direct contact with soiled particles.

Brand

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.

Applications

The CS Instruments FA 510/515 Dew Point Sensor For Adsorption Dryers is suitable for a wide range of applications where dry air is mandatory:

Adsorption Dryers: Monitoring desiccant performance to ensure low dew points (down to -80°Ctd) and optimize regeneration cycles.
Compressed Air Systems: General monitoring of air quality in main lines and point-of-use.
Refrigeration Dryers: Verifying the performance of cooling dryers (as noted in the standard documentation).
Granulate Drying: Ensuring dry air for plastic injection molding processes.
Breathing Air: Verifying compliance with safety standards in medical and industrial breathing air systems.

Additional Informations

Standard measuring chamber
- for compressed air up to 16 bar
Control and calibration set for dew point sensors
is screwed onto the dew point sensor and therefore enables an easy and low-priced possibility for on-site control and calibration down to -20°Ctd.
