Liquid Analyzer System Snags FM Approvals

Electro Chemical Devices’ X80-B88-S88 liquid analyzer system features a sealed explosion-proof enclosure and intrinsically safe sensors, and now carries FM approvals, making it safe for use in hazardous areas. The system features a NEMA 4X, IP66 sealed 316 stainless-steel design.


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 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. 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.


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 recognized 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.


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. 


Additionally, 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. For more details, checkout the datasheet.
