About the CS82

The CS82 Intrinsically Safe Submersible Pressure Transducer is a high strength sensor designed for liquid level measurements in intrinsically safe locations. The CS82 features stainless steel (316L and 304) construction and an ETFE cable jacket for compatibility with a wide variety of liquids. Precision welds and a high strength Nylon strain relief prevent liquids from entering the transducer while a wide diameter vent tube quickly equalizes the barometric pressure within the sensor body to ensure accurate level measurements. The CS82 is available in various output signals including 4-20mA loop powered for long distance transmissions and voltage outputs for low power and low current consumption applications.

Caution must be taken when installing and operating the CS82 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.

Standard and custom cable lengths are available to simplify installation.

Reliable Liquid Level Measurement

Certified Safe

The CS82 Intrinsically Safe Submersible Pressure Transducer is certified by CSA to operate safely in Class I, Division 1 Intrinsically Safe rated locations when used with an approved current limiting barrier. This transducer is designed with a high strength 300 series stainless steel (304 & 316L) metallic construction, corrosion resistant ETFE cable jacket, and a Nylon strain relief for compatibility in a wide range of liquids.

The CS82 features a configurable design, allowing Core Sensors to tailor the transducer to your applications operating requirements. Have a limited voltage supply at your installation? No problem! The CS82 is offered in a low power configuration, capable of operating from an unregulated power supply of 3-5VDC and consuming 3mA or less of current. Need an extra long cable length? No problem! Core Sensors offers both standard and custom cable lengths, ensuring you have enough cable to simplify your installation

The CS82 Intrinsically Safe Submersible Pressure Transducer is also great for non-submersible applications. The standard nose cone can be substituted for 1/4″ or 1/2″ Male NPT threads for threaded installation, commonly where flooding is a concern.
