IM 12B6J8-01E-E

2.5 Operating range

pH : 0 to 14

ORP : -1500 to 1500 mV

rH : 0 to 100

Temperature

- Dome shape : -10 °C to 105 °C (14 °F to 221 °F)

- Flat surface : +15 °C to 105 °C (59 °F to 221 °F)

Pressure :

Conductivity : > 10 µS/cm

Note: The pH operating range is 0-14 pH, but using the sensor at temperature- and / or

pH-extremes will seriously shorten the lifetime.

Note: Sensor is suitable for pure water applications.

2.6 Transmission signal (Data + and Data -)

General : Bi-directional digital communication (RS 485) with

limited MODBUS support

Data rate : 9600 b/s (8,E,1)

Output function : pH or temperature compensated pH

ORP, pH compensated ORP, rH

Temperature

Junction resistance

Sensor details (Model, Serial Number, production date)

Sensor calibration data (zero, slope, temperature offset)

Sensor status signals (e.g. Glass impedance detection)

Note: The output functions and settings of the sensor are accessible using a dedicated

device such as the Yokogawa FLXA analyzer.

2.7 Power supply (Supply+ versus Supply Gnd)
