Abstract
Disclosed is a leakage detection device, which causes an operational amplifier of a leakage detection circuit to generate different output voltages based on resistance of liquid detected by leakage sensor and compares the output voltage with a reference voltage to determine whether the leakage sensor comes into touch with liquid and to provide a transistor VBE with a positive bias or a negative bias to turn on or off a common-emitter NPN transistor (C-E terminal) of a leakage signal output circuit for driving a relay to generate an ON or OFF signal for making a programmable logic controller (PLC) generate a control signal. Thus, a leakage detection device that can detect high resistance liquid and simultaneously effect detection at long distance is provided.
