ECD Model X80 Universal Transmitter

The ECD Model X80 Universal Transmitter is a single- or dual-channel transmitter designed for the continuous measurement of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general-purpose industrial environment.

The transmitter digitally communicates with any ECD Model S88 or S80 Intelligent Sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter. The same transmitter can be used for any of the measurements; eg, plug an S88 Conductivity Sensor into a Model X80 pH transmitter and it will automatically reconfigure into a conductivity transmitter. There is no longer any need to inventory multiple instrument types, as the one transmitter will automatically configure to any of the listed measurements.

The Model S88 Intelligent Sensors facilitate two-way communication with the Model X80 transmitters. The type of sensor, identity and serial number are stored in the sensor’s memory along with calibration registers. The sensors are calibrated at the factory, so they are ready to use when connected to the transmitter. The sensors are waterproof and submersible, with all internal components epoxy encapsulated inside the ¾″ OD housing.

The transmitter features a large, easily viewed LCD display. Loop-powered instruments have black lettering on a grey background, while the 24 VDC powered instruments have blue lettering on a white background when the LED backlight is on. The product has three easily switchable main display screens: the data screen, the millivolt screen and the graphical display screen (six screens for two channel units).

The data screen displays the measurement type, the measured value with units, the % milliamp output of the 4–20 mA channel and the temperature. The mV screen displays the measurement type, the raw mV signal from the sensor, the % milliamp output of the 4–20 mA channel and the temperature. The graphical screens display the measurement type, the measured value with units and a graphical representation of the % milliamp output. Three graphical styles are available: a trend line, a bar graph or a gauge.
