Wiring; Connecting Conductivity Sensor To Analog Host System - YOKOGAWA SC41 Instruction Manual

5. WIRING

The SC41, SC42 and SC49 sensors are provided with two type of fixed connectors.
The standard cable used to connect the sensor with Amphenol connector to the analyzer
is the WU40. These cables are available up to 25 meters.
The standard cable used to connect the sensor with VP connector to the analyzer is the
WU10 or WE10. These cables are available up to 20 meters.
When a longer cable run is necessary (maximum cable run is 60 meter for the analog
sensor setup), this can be done by using the WF10/WE10 extension cable in combination
with the BA10 connection box.
The connection of the WU40 cable (+ BA10 connection box with WE10/WF10 cable) to
the Yokogawa Contact Conductivity analyzer are given in table 7.
When even longer cable runs are required, we recommend to use the digital SENCOM
concept where cables runs up to 200 meter are possible.
This can be done using the VarioPin sensor types in combination with a SA11 Smart
adapter, WU11 digital connection cables and BA11 Active Junction Box.
For a complete overview of products and possibilities for connecting multiple sensors to a
host using the digital SENCOM concept: Please see: SA11 GS12A06S01-00EN
