The CS54 non-incendive differential pressure transducer is a high-strength sensor designed for differential pressure measurements of liquids and gases in Class I, Division 2 hazardous locations. A 316L SS oil-filled sensor element provides excellent stability over a wide operating temperature range while offering corrosion resistance against various liquids and gases. Differential pressure ranges up to 50 PSI are available with 1/4″ MNPT or FNPT process connections.
In an effort to simplify installation in Class I, Division 2 hazardous locations, the CS54 is offered with an integral Turck® Minifast® electrical connection.
When combined with a CSA Division 2 approved Turck® cordset and a Turck® Lokfast Guard, there is no requirement for a conduit to be installed over the cable*. This not only makes installation easy but also makes switching out sensors less cumbersome. Core Sensors can supply all components as a complete package.
