Title: Motor-driven valve tester
Inventor: TOYONAGA HIDETO
IPC: G01M13/00
Filed: 1986-07-02
Abstract: PURPOSE:To obtain a highly accurate measured value of a working time with one opening-closing action of a motor-operated valve while enabling simultaneous measurement of a voltage and a current, by inputting signals of voltage and current and working time signal to print out measurement data of the voltage and current. CONSTITUTION:A voltage converter 22 detects a power source voltage of a motor- operated valve 1 and outputs a voltage signal while outputting a measuring signal of working time. A current converter 23 detects a power source voltage and outputs a current signal. A measurement start signal transmitted from the converter 22 and a measuring signal transmitted from a limit switch of the motor-operated valve 1 are inputted into a time measuring device 24 to detect working time of the motor- operated valve and a working time signal is outputted. With such an arrangement, the voltage signal and current signal transmitted from the converters 22 and 23 and the working time signal transmitted from the measuring device 24 are inputted into a display device and measured values thereof are displayed simultaneously. This provides a highly accurate measured value of the working time with one opening- closing action of the motor-operated valve without losing original characteristics of the voltage, current and measurement.
