Abstract
A steam trap operation detector provided with a vibration detecting section and a arithmetric section. The detecting section includes a probe, a diaphragm for generating ultrasonic vibration in response to mechanical vibrations sensed by the probe and a vibration sensor for converting the ultrasonic vibration into an electrical signal. The detector also includes an arthimetric section for receiving an amplified signal from the vibration sensor and processing the same into information indicative of the operation of the steam trap.
