PURPOSE: A hydrogen sensor with a replaceable sensor unit is provided to improve the convenience for replacing a sensor and reduce manufacturing costs because only the sensor unit receiving signals is replaced instead of replacing all components constituting a sensor.;CONSTITUTION: A hydrogen sensor with a replaceable sensor unit comprises an electric signal device(110), a piezoelectric element(120), a sensor unit(160), and a sensor unit attaching/detaching member(140). The electric signal device generates and detects electric signals. The piezoelectric element is connected to the electric signal device and generates ultrasonic waves when receiving the electric signals. The sensor unit is connected to the piezoelectric element and the ultrasonic waves are transmitted from the piezoelectric element to the sensor unit. The sensor unit attaching/detaching member is comprised in between the piezoelectric element and sensor unit and inserts and separates the sensor unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Electrical signal device; (120) Piezoelectric element; (140) Sensor unit attaching/detaching member; (160) Sensor unit
