Applications

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.

* Accuracy includes non-linearity, hysteresis and non-repeatability
** Max line pressure is the highest common mode pressure that can be applied to the sensor without damage
*** Overpressure and burst pressure are the maximum differential pressure that can be applied to the high or low side before damage to the sensor will occur

Approvals for the Core CS54 series include:

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

Note: Must use an approved barrier to maintain listed certifications. See page 4 of the datasheet for entity parameters.

Typical applications for the CS54 Non-Incendive Differential Pressure Transducer include:

  • Filtration
  • Cryogenic bulk tank level measurement
  • External fuel tank level measurement
