Explosion-proof liquid analyser for hazardous areas

The rugged, modular, versatile X80 Universal Transmitter and S88 Intelligent Sensors from Electronic Component Devices, Inc. (ECD) deliver an easy to-use plug-and-play, reliable precision liquid measurement analyser solution compatible with advanced operating and control systems for harsh industrial and other environments.

The highly intelligent X80-S88 Analyzer System is an ATEX, IECEx, FM and CSA certified product family, which features a sealed 316 stainless transmitter and sensors offering an impressive pedigree of hazardous area safety approvals. With a selection of sensors, materials and electrodes all designed for specific applications, the S88 family of sensors provide long sensor life and lower maintenance cost in many installations that other sensors cannot survive.

For example, the oil and gas and chemical industries (as well as others) require liquid analysis of corrosive fluids, cooling water, rinse water and other liquids to protect equipment, ensure quality production and for environmental compliance. The X80-S88 Analyzer is ideal for monitoring these fluids including: pH as an indicator of sour gas and in overhead crude; pH, ORP, conductivity and chlorine in cooling tower operation; and pH, ORP, DO and various pIONs in wastewater effluent.

ECD’s Model X80 Series provides the same capabilities and general feature set as the general purpose ECD T80 Universal Transmitter. Various configurations are available as single or dual channel for the continuous measurement of pH, ORP, pIONs, dissolved oxygen, turbidity, conductivity or resistivity with standard Modbus or optional HART digital bus communications and three optional alarm relays. With its advanced electronics, the modular X80 Transmitter communicates with any Model S88 Intelligent Sensor, automatically configuring the transmitter’s menus and display screens to the desired measurement parameter.

Designed with a rugged 316 stainless steel housing and large easy-to-read sealed display, the explosion-proof modular X80 transmitter and ECD’s S88 sensors eliminate the need to inventory multiple instruments. The advanced S88 sensors facilitate two-way communication with the X80 transmitter and automatically convert it to the chosen parameter. Where feasible, the X80 also can be used with standard S80 sensors at reduced cost to measure the same parameters in non-hazardous areas.

Highly intelligent, the S88 sensor’s measurement parameter, its identity and serial number are all stored in the sensor’s memory along with calibration registers for parameter measurements. These sensors are pre-calibrated at the factory, and so they are ready to use right out of the box and can be immediately connected to the X80 transmitters. The rugged S88 sensors are waterproof and submersible with all internal components epoxy encapsulated. The S88 sensors have two universal sensor designs; Insertion/Submersion or Valve Retractable with flared end to prevent blow out. The standard S88 sensors have 316 stainless steel housings although various materials of construction are available to maximise sensor performance while minimising cost of ownership.

The S88 sensors are the smart sensor choice for a wide variety of applications, including oil and gas production, petrochemical refining, electric power generation, water and wastewater treatment and more. The standard S88 sensors have a rugged 19 mm OD 316 stainless steel body with a 3 m cable or an optional waterproof detachable cable assembly.

The X80 transmitter features a large (2.75 x 1.5 inch) easily viewable 128 x 64 pixel LCD display with three easily switchable main display screens for data, millivolts and graphics. The display comes with a grey background and black lettering for loop powered instruments or with a blue background and white lettering with LED backlighting on 24 VDC powered instruments.
