ProH2O Water Leak Detection Application Guide

SENSOR CABLE ­ OVERVIEW

ProH2O  Sensor  Cable  is  a  linear  sensor  for 
the  detection  of  water  leaks.  When  water 
comes into contact with the detection cable a 
controller can detect changes in the electrical 
characteristics  of  the  cable  and  signal  an 
alarm  or  other  action.  The  sensor  cable  is 
available  in  pre­terminated  lengths  for  simple 
assembley  and  extension.  Non­sensing  pre­
terminated  lengths  are  also  available  when 
the  cable  is  to  pass  through  areas  which  do 
not require protection.
