Liquid Leakage Point Sensor

F03-16PS

A New Liquid Leakage Point Sensor Has Been Added 
to the K7L Series. Fluoroplastic Coating on the 
Bottom Electrode Ensures Chemical Resistance.

• Can be used in conjunction with Sensing Bands.
• Stud screw mounting requires no tools for installation.
• No tools means the Sensor can be wiped clean quickly and easily.
• The optional Mounting Bracket enables faster installation than three-screw 

mounting.

• Connect multiple Sensors to one K7L-AT50 Amplifier for significant cost 

savings.
