New FM approved liquid analyser system is safe for hazardous area duty

With its sealed explosion-proof enclosure and intrinsically safe sensors, the rugged X80-B88-S88 Liquid analyser system from Electro Chemical Devices (ECD) now features FM approvals, making it safe for use in hazardous areas in support of the most demanding applications within oil/gas production sites, refining operations and storage terminals; chemical processing plants; electric power generation; fertilizer production and storage; and other industries.

Wherever potentially explosive or combustible combinations of gases, liquids and wastewater must be processed and/or treated, the newly FM approved X80-B88-S88 analyser system is ready to provide highly precise measurement of pH, ORP, DO, conductivity, resistivity or various specific ions. The X80-B88-S88 analyser system features a NEMA 4X, IP66 sealed 316 stainless steel design that is FM approved.

The X80 transmitter is approved for Class I, DIV 1, Groups B, C, D; T4 Ta = -40°C to +80°C; Class I, Zone 1, IIB+H2 T4 -40° to +85°C. The B88 Barrier is approved for Class I, DIV 1 Groups B, C, D; T5 Ta -40°C to +80°C; Class I, Zone 1 IIB+H2 T5 -40°C to +80°C. The versatile S88 Sensor is intrinsically safe for Class I, DIV 1, Groups B, C, D; T5 Ta = -40°C to +80°C; Class I, Zone 0 IIB+H2 T5 -40°C to +80°C.

The petrochemical industries require liquid analysis of corrosive fluids, cooling water, rinse water and other process liquids to protect equipment, ensure quality production and for environmental compliance. The FM approved ECD X80-B88-S88 analyser 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, turbidity, DO and various pIONs in wastewater effluent. ECD also offers ATEX and IECEx certifications with other configurations of the X80-S80 analyser system.

ECD’s Model X80 universal transmitter is available as either a single- or a dual-channel instrument for continuous measurement 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 X80 Transmitter and ECD’s S88 sensors eliminate the need to inventory multiple instruments. Each S88 Sensor contains a B88 Barrier comprising energy limiting devices to comply with FM hazardous location requirements. Connection between the X80 and B88 Barrier is accomplished using flameproof conduit and installation practices recognised by National, State, and local codes (NFP, NEC, etc.). The S88 sensor connects to the B88 Barrier with a MiniFast Connector with tamper-proof lockout guard.

Highly intelligent, the S88 sensor’s measurement parameter, its identity and serial number are all stored in the S88 sensor’s memory along with calibration registers for parameter measurements. These sensors are pre-calibrated at the factory, and so they’re 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 are the smart sensor choice for a wide variety of applications, including oil/gas production, petrochemical refining, electric power generation, water and wastewater treatment and more. The S88 sensors feature two universal sensor designs: (1) insertion/submersion or (2) valve retractable with flared end to prevent blow out. The standard S88 Sensors have a rugged 0.75-inch O.D. 316 stainless steel body with a 10-foot (3 meter) 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, millivolt and graphics. The display comes with a gray background and black lettering for loop powered instruments or with a blue background and white lettering with LED backlighting on 24 Vdc powered instruments.
