The CS51 non-incendive low pressure transducer from Core Sensors is a high-strength sensor designed for use in hazardous environments with various approvals and certifications. Available with low pressure ranges from 1 PSI up to 49 PSI with an accuracy of ≤±0.25% BFSL **. The CS51 has a selection of electrical output options, as well as a choice of process connections and wetted materials available with an operating temperature range of -40°C to +80°C and a media temperature range of -40 to +125°C. The Robust design and variety of configurable options make the CS51 series a versatile pressure transducer designed to operate in some of the harshest conditions. Utilising an all welded stainless steel one-piece diaphragm with no internal O-rings or welds, the series also offers a minimum ingress protection of IP65. The CS51 is an excellent solution for applications such as natural gas compression, hydrogen compression and storage, and process control instrumentation.
In an effort to simplify installation in Class I, Division 2 hazardous locations, the CS51 Non-Incendive 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.
*Core Sensors recommends confirming hazardous location installation requirements with your local inspector as each installation is unique.
