WU20(D) Cables for Industrial Applications

When you need optimal pH or Redox measuring results,

the complete measuring loop not only requires highly qualified

sensors and transmitters but also the special purpose sensor cables.

The program of Yokogawa includes a range of high quality,

low-noise cables for accurate transmission of low voltage signals even in areas where interference is present. They have a shield with an internal anti-noise sheath and can be connected to all pH and ORP (Redox) electrodes fitted with an O-connector.

At the electrode end the cables are provided with a socket having spring gilded contacts for secure connection to the sensor.

The combination electrode plug and cable socket is

watertight and temperature resistant up to 125ºC. It meets

the requirements of IP 65.

Features

• Internal anti-noise sheath for accurate measurement.

• Gold plated spring O-connectors parts, for good electrical contact under the most severe conditions.

• Coaxial plug and socket with watertight sealing that meets the requirements of IP 65.

• Cables for industrial applications and for laboratory use are available.

Coax Cables

These cables are for connecting to single or combined sensors fitted with an O-plug. For use at higher temperature specifications (up to 110ºC continuously or 125ºC for short times) and the most severe conditions.

Triax Cables

These cables are for connecting to combined sensors fitted with an O-plug or to single sensors with an O-plug for use in areas where eletrical interference is present. They have both inner, and outer shielding. In areas where electrical interference

is likely we recommend to use the Triax electrode cable type WU20(D)-LT. marked with a blue strip.

Notes:

1. For industrial applications the cables can be colour coded with the following marks:

- Measuring electrode : red

- Reference electrode : yellow

- Temperature electrode : green

- Combined electrode : blue

Adhesive

markers are provided for this purpose and should be fitted to both ends of the cables.

2. To secure optimal conditions, the cables may not be

damaged or shortened. For protection of the cables there are special hoses available of 5 or 10 mtr.

(K1500CJ, K1500CK respectivily)

3. Suitable for use in intrinsically safe areas.
