Wet / Wet – From 0.5 to 1,000 PSID – Versatile Packaging
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 1,000 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.
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 0.5 PSID (14″ water column or 35 millibar) up to 1,000 PSID in both uni-directional and bi-directional.
Multiple electrical connections and outputs are available.
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.

Standard lead time is typically two to three weeks with expedites available. Contact us with the pressure range, output and cable length required.
*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.
*IP Rating is dependent on electrical termination selected. Contact factory for more information.

Intrinsically safe protection works by limiting the electrical energy that can reach the hazardous area. The CS84 itself doesn't do that limiting; an IS barrier or galvanic isolator installed in the safe area does. Without a certified barrier matched to the CS84's entity parameters (listed on page 4 of the datasheet), the installation isn't actually intrinsically safe even though the sensor is IS-rated. For installations in Class I Division 1 areas without a barrier, consider the CS64 explosion-proof differential pressure transducer.
The CS84 supports multiple electrical connection types (cable, M12x1, DIN connector, etc.), and the ingress protection is only as good as the connector actually installed and properly mated — IP65 minimum assumes the connector is correctly attached. If a design calls for a specific IP rating, it's worth confirming which electrical termination option delivers it rather than assuming the datasheet's headline number applies to every configuration. Talk to Core Sensors about your application and we'll help guide you to an electrical connection that suites the environmental conditions and the application.
Differential pressure transducers measure the difference in pressure between two points.
Wet/wet means both sides of the sensor are in contact with process media.
Dry/dry means neither side sees process media and is limited to dry gases.
Wet/dry is a mix of the two. An application might be a fuel to air differential pressure or water to hydraulic fluid in an ROV used for pressure compensation.
The CS84's fully welded construction without internal O-rings is what allows it to be configured for any of the three without a different sensor design for each.
The CS84 series is designed for differential pressure measurement. While two independent pressure transducers can be used for differential pressure measurement, the CS84 series offers some advantages. It offers higher accuracy; with two independent pressure transducers, you will need to combine the accuracy specifications. It decreases the number of inputs required to measure differential pressure thus reducing the number of cordsets and barriers. It offers a compact design.
