Frequently Asked Questions

Level Controller Topic: One Liquid Leakage Amplifier to Detect Leakage at Multiple Locations

 

FAQ No. FAQ00849

 

Question

 

Can a single K7L Liquid Leakage Amplifier be used to detect leakage at multiple locations?
 


Answer

Yes. If Terminal Blocks are used to connect Sensing Bands in parallel, leakage can be detected in more than one place with only one K7L Amplifier.

If there is a leak in this case, the K7L does not indicate which Sensing Band detected the leak.

 

Cable Length: 50 m max.; Sensing Band Length: 10 m max.

 

Note 1: When wiring, be sure not to exceed the maximum possible wiring distances for both the connecting cable and the Sensing Band. Exceeding these distances may lead to faulty operation. Connect one Sensing Band to each Terminal Block.

Note 2: This configuration cannot be used with the K7L-AT50D.
