Connecting a transducer with RG62 coaxial extension cable
If you are replacing an older Siemens Milltronics Ultrasonic Level Controller with a new
MultiRanger where an RG62 coaxial extension is fitted and you are unable to replace the
extension with a new cable, please refer to connection diagram below. Please note that
the noise immunity performance will be similar to our older model ultrasonic level
controllers if you use coaxial cable.
Existing installation
RG62 coaxial cable has been used to make the extension. The level controller might be a
MultiRanger Plus, HydroRanger, HydroRanger Plus or one of our other level controllers.
MultiRanger 100/200 Installation (for retrofitting MultiRanger Plus
Installations)
Connect with a 0.1 µ F (100v or greater) capacitor (included with MultiRanger) between the
shield and negative terminals. Connect centre core of the coaxial to the positive terminal
and the screen to the negative terminal.
