摘要： PROBLEM TO BE SOLVED: To set a δA/δt (δ represents a round d, or a partial differentiation sign) component obtained from signal lines in an electromagnetic flowmeter of the asymmetrical excitation type to be an appropriate size. SOLUTION: The electromagnetic flowmeter includes: a measurement tube 1; electrodes 2a, 2b; an excitation coil 3 for applying a magnetic field which is asymmetrical with respect to a plane PLN and changes temporally to a fluid; a signal conversion unit 5 for extracting a δA/δt component from combined electromotive force of the electromotive force of the δA/δt component which is irrelevant to the flow rate of the fluid and is caused by the temporal change of the magnetic field and the electromotive force of a v×B component which is caused by the flow rate of the fluid; a flow output unit 6 for removing the fluctuation factor of a span which is a coefficient on the magnitude of the flow rate V of the v×B component in the combined electromotive force on the basis of the δA/δt component and calculating the flow of the fluid from the result with the fluctuation factor removed; and signal lines 7a, 7b which are arranged so that they incline with respect to the direction of the magnetic field which is parallel to the plane PLN and that electromotive force is generated through the temporal change of the magnetic field.

摘要： PROBLEM TO BE SOLVED: To provide a relay end-of-service-life forecasting device that can accurately forecast the end-of-service-life of an electromagnetic relay.SOLUTION: By diagnosing the life of a relay 10 based on the time from when the application of power to the relay 10 is started or when the application of power to a relay coil is stopped by a control unit 2 till when the actual opening or closing of the relay 10 is detected, the end of the service life of the relay 10 can be accurately forecasted without a remarkable decline in forecasting accuracy due to the effects of load conditions and environmental conditions. Specifically, forecasting the end of the service life of the relay 10 based on time, increases the forecasting accuracy because time is a value that is not affected by the external environment. In addition, the end of the service life is forecasted based on the actual opening/closing of the relay 10, a fault in the relay 10 can be immediately detected, but at the same time, the effects due to individual differences can be eliminated, resulting in accurate forecasting of the end of service life of the relay 10.
摘要翻译：要解决的问题：提供可以准确预测电磁继电器使用寿命终点的继电器使用寿命终了预测装置。解决方案：通过根据时间从当开始向继电器10施加电力时，或者当通过控制单元2停止对继电器线圈施加电力时，直到检测到继电器10的实际打开或关闭，则终止使用寿命由于负载条件和环境条件的影响，可以准确预测继电器10的预测精度明显下降。具体地，基于时间预测继电器10的使用寿命的结束，由于时间是不受外部环境影响的值，因此增加了预测精度。此外，基于继电器10的实际开/关来预测使用寿命的终止，可以立即检测继电器10的故障，但同时可以消除由个体差异引起的影响，从而准确预测继电器10的使用寿命。
