Typical Signals of Leakwise Sensors
Each Leakwise sensor has a cable with three wires named: DET+, DET-, DET Sig.
DET+ : +12VDC supply in reference to DET-. Supplied current is the sum of the currents
through the other two wires.
DET- : Power and signal ground. Returning current between 6 to 9mA, no matter if the sensor
is in air or in water.
DET Sig. : Sensors' current output signal, value depends on sensor model and on liquid
condition around the sensor, typically as follows:
Typical signal values are:
ID-221: In Air: 0.65 to 0.85 mA
In clean Water: 1.00 to 1.30 mA
ID-223 (all models): In Air: 0.90 to 1.10 mA if the sensor is 20 mm or more above bottom
flange.
In Air: 0.65 mA when the sensor is resting on bottom flange.
In Oil layer of 30 mm or more: 0.97 to 1.10 mA
In clean Water: 1.60 to 1.90 mA
ID-225/100: In Air: 1.00 mA.
In Oil layer of 110 mm or more: 1.20 mA
In clean Water: 3.20 to 3.40 mA
ID-225/200: In Air: 1.10 mA.
In Oil layer of 230 mm or more: 1.44 mA
In clean Water: 4.30 to 4.50 mA
ID-227: In Air: 0.80 to 1.00 mA.
In clean Water: 1.35 to 1.80 mA
The signal gets lower below Water signal as oil layer increases.
