About the CS51

The CS51 Non-Incendive Low Pressure Transducer is a high strength sensor designed for low pressure measurements in Class 1, Division 2 hazardous locations. The CS51 features an all welded stainless steel construction, offering a minimum IP65 rating. A wide range of configurable options make the CS51 a versatile pressure transducer designed to operate in some of the harshest conditions. The CS51 is an excellent solution for applications such as natural gas compression, external fuel tank level measurement and process control instrumentation.

Caution must be taken when installing and operating the CS51 in known Class I, Division 2 hazardous locations. Please review the Non-Incendive Operating Instructions prior to installation.

Approvals/Certifications

  • CSA Class I, Division 2, Groups A, B, C, D T4
  • ABS (American Bureau of Shipping) Approved
  • CE

Now Available With A Turck Mini-Fast Connection

No Conduit Installation Required!

In an effort to simplify installation in Class I, Division 2 hazardous locations, the CS51 Non-Incendive Low Pressure Transducer is offered with an integral Turck Mini-Fast electrical connection.

When combined with a Turck cordset (with ITC rated cable) and a Turck Lokfast Guard, there is no requirement for 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. Click here to learn more about the Turck Mini-Fast electrical connection.

* Core Sensors recommends confirming hazardous location installation requirements with your local inspector as each installation is unique.
