Wiring; Connecting Conductivity Sensor To Analog Host System - YOKOGAWA SX42 Instruction Manual

5. WIRING

The SX42 threaded models are provided with a fixed connector. The standard cable used
to connect the sensors with Amphenol connector to the analyzer is the WU40. The
standard cable used to connect the sensor with VP connector to the analyzer is the
WU10/WE10. These cables are available up to 25/20 meters. When a longer cable run is
necessary (maximum cable run is 60 meters), this can be done by using the WF10
extension cable in combination with the BA10 connection box. The connection of the
WU40 cable, WU10 cable and WF10 cable to the Yokogawa Contact Conductivity
analyzer are given in table 7 and 8.
The sensors with VP connector contain an embedded ID chip allowing direct connection to
our SA11 Smart Adapter. The SA11 Smart Adapter can be applied in processes with
ambient temperature up to 125°C.
If ambient temperature is higher than 125°C the connection to Smart Adapter should be
made using the WE10 extension cable in between the Smart Adapter and the sensor.
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 Vario Pin 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
