EC socket
6-pin DIN socket for connection of the conductivity cell with 2, 3 or 4
poles and a temperature sensor.
Pin layout:
3
2
4
Pin 1 : pole no.1
Pin 2 : pole no.2
6
Pin 3 : pole no.3
1
5
Pin 4 : pole n°4, also connected to pin no. 5
Pin 5 : 0 V (ground)
Pin 6 : temperature sensor
Potential imposed between poles 2 and 3: ±200 mV constant for all
conductance ranges.
The current passing through poles 1 and 4 is measured. The potential
between poles 1 and 4 cannot exceed 3 V in absolute value.
The following Radiometer Analytical conductivity cells can be
connected to the EC socket:
