Embracing Challenge Liquid alarm sensor KS3 / KS3 EX, KS3 EX PEEK, KS3 EX PEEK SS, KS3 EX SS for non-conductive and conductive media Special Features ■ Sure detection even of minimal liquid quantities ■ Can be integrated into M&C-universal filters and flow chamber ■ Explosion proof version according to ATEX for zone 1 ■ Rugged aluminium enclosure ■ Extended operating temperature range of -20 °C to 50°C (—4 °F to 122 °F) for EX versions Application The liquid alarm sensor type KS3... is an adequate replacement for the previous KS2... model. The KS3... has a rugged aluminium enclosure. Additionally, the operating temperature range for the KS3 EX versions has been extended to -20 °C up to 50°C (~-4 °F to 122 °F) in connection with the renewed Type Examination Certificate. Liquid alarm sensors are used in gas sample conditioning systems for monitoring gas cooling and condensate drain-off devices in order to provide protection for downstream analysis instruments. The monitoring devices KS3 / KS3 EX versions signal reliably the penetration of non conductive (e.g. alcohol) and conductive (e.g. water) liquid in the event of cooling or condensate drain-off equipment being defective, thus avoiding expensive down time as well as high repair costs for analysis instruments. In the event of an alarm, power for the sample gas pump must be switched off or a solenoid valve must be switched idle in the sample conditioning system. directly to the active sensor surface. Even the smallest liquid droplets will trigger a sure and rapid alarm. The sensors are mounted with the 16 mm 0 stainless steel body in the GL-25 connector of the universal filter F..-..-D or the condensate pot TG1 or in the flow chamber LS/KS. Description The M&C liquid sensors KS3 / KS3 EX versions work on the principle of capacitive measurement and is suitable for non-conductive and conductive media. A pre-amplifier is integrated in the sensor housing and is connected with the necessary external electronic controller via 2- resp. 3-wire. For KS3 the required electronic controller is available in various versions, FA1.1; FA1.4 and is described in the separate data sheet 9.5. The M&C liquid sensors KS3 EX, KS3 EX PEEK, KS3 EX PEEK SS and KS3 EX SS for use in hazardous areas and media should only be used in connection with electronic controller WE77.Ex1 or KFA6-SR2-Ex1W. The M&C liquid sensors KS3 / KS3 EX versions are constructed in such a way that any droplets of liquid in the sample gas are attracted Technical specifications and illustrations are without obligation, subject to modifications. 05.18 - 1.01.00 M&C TechGroup Germany GmbH • Rehhecke 79 • 40885 Ratingen • Germany info@mc-techgroup.com • www.mc-techgroup.com • Fon +49 2102 935-0 • Fax +49 2102 935-111
