Performance data

Conductivity measurement

Minimal scale

2 % of the full scale (i.e. for the sensor with C = 0.1: range from 100…104 µS corresponds to 4…20 mA

current output)

Temperature measurement

Measuring range resolution

0.1 °C (0.18 °F)

Minimal scale

10 °C (i.e. + 10…+ 20 °C (+ 50…+ 68 °F) corresponds to 4…20 mA)

Electrical data

Operating voltage

• 3 outputs transmitter (2-wire) variant: 14…36 V DC, filtered and regulated

• 4 outputs transmitter (3-wire) variant: 12…36 V DC, filtered and regulated

Connection to main supply: permanent, through external SELV (Safety Extra Low Voltage) and LPS

(Limited Power Source) power supply

Current consumption

With sensor

• ≤ 1 A (with transistors load)

• 3 outputs transmitter (2-wire) variant: ≤ 25 mA (at 14 V DC without transistors load, with current loop)

• 4 outputs transmitter (3-wire) variant: ≤ 5 mA (at 12 V DC without transistors load, without current

loop)

Output

Digital output

Voltage supply cable

The female M12 connector and/or the male M12 connector are not included in the delivery and must

be ordered separately, see chapter “11.5. Ordering chart accessories” on page 23.

For these connectors, use a shielded cable with:

• diameter: 3…6.5 mm

• cross section of wires: max. 0.75 mm²

Process/Pipe connection & communication

Electrical connection

• 3 outputs transmitter (2-wire) variant: 1 x 5-pin M12 male connector

• 4 outputs transmitter (3-wire) variant: 1 x 5-pin M12 male and 1 x 5-pin M12 female connectors
