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∝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.
