Claims

[Scope of utility model registration request]

An abnormality detection device consisting of a detector main body 10 made up of a piezoelectric ceramic 8 for vibration detection and a resistor 9 connected in parallel, and a connector 11 that connects the detector main body 10 and the electric line 7 in a freely disconnectable/connectable manner. Part 1; Abnormal vibration signal P from the piezoelectric ceramic 8
an amplifier section 2 which inputs a through a capacitor 13;
a line abnormality detection unit 4 that detects the voltage VR across the resistor 9 and transmits a line abnormality signal Pc when the voltage VR is outside a certain range; an abnormal vibration signal pb and a line abnormality signal from the amplification unit 2; An abnormality alarm device comprising an alarm output section 5 activated by PC.
