Datasheet Operating Instructions CSA Certificate of Compliance

**Disclaimer: Unless otherwise agreed in writing, Core Sensors products are not authorized for use in applications including medical devices, life support systems, in-flight aerospace, nuclear or any other application where the product failure could result in personal injury or death.

About the CS84

The CS84 Intrinsically Safe Differential Pressure Transducer is a high strength sensor designed for differential pressure measurements of liquids and gases in Class I, Division 1 Intrinsically Safe locations. The CS84 features an all welded stainless steel construction for a minimum IP65 rating. 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. A wide range of configurable options make the CS84 a versatile pressure transducer that can be designed to operate in some the harshest conditions.

Caution must be taken when installing and operating the CS84 in known Class I, Division 1 hazardous locations. Please review the Intrinsically Safe Operating Instructions prior to installation.

Approvals/Certifications

  • CSA Class I, Division 1, Groups C, D T4
  • Class I, Zone 0 AEx ia IIB T4 Ga (Ex ia IIB T4 Ga)
  • ABS (American Bureau of Shipping) Approved
  • CE

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

Wet/Wet – Up to 50 PSID – Versatile Packaging

Versatile Differential Pressure Measurement

The CS84 Intrinsically Safe Differential Pressure Transducer is the ideal solution for differential pressure measurement in hazardous applications such as filter condition monitoring, sealed tank level measurement, and flow measurement across an orifice.

The CS84 features a fully welded design without any internal O-rings or seals, allowing for wet/wet, wet/dry, or dry/dry applications.

Differential pressures are available as low as 1 PSID up to 50 PSID in both uni-directional and bi-directional.

Multiple electrical connections and outputs are available.
