    • PURPOSE: To provide a solenoid valve having a sensor having improved safety and reliability by simplifying the construction of and facilitating the assembly of monitoring means for monitoring adaptability of input/output pressures in the solenoid valve 1 and the changed-over condition of a valve element. CONSTITUTION: The solenoid valve 1 with the sensor comprises the solenoid valve 1, a base 2 for feeding/discharging a pressure fluid to/from ports P, A, B, EA, EB of the solenoid valve 1 and an intermediate block 3 arranged between the solenoid valve and the base. The intermediate block 3 is provided with communication passages 53, 54A, 54B, 55A, 55B for individually communicating the ports of the solenoid valve, with flow passages in the base and is also provided with a conduit 56 traversing the communication passages. The conduit is provided with a pressure introduction port 58 opened to the communication passage 53, in which a pressure is to be detected, and the intermediate block 3 is provided with a pressure sensor 60 for detecting the pressure introduced through the conduit.

    • PURPOSE: To surely detect the abnormality of a solenoid valve before failure by judging whether the switching operation is normal or abnormal based on the operation time detected from the solenoid valve. CONSTITUTION: The position of the stroke end of a spool is detected by the detection means attached to a solenoid valve, and spool movement starting time until the spool starts its motion from the stroke end after the drive signal of the solenoid valve became ON or OFF, and spool movement finishing time until the spool reaches the stroke end are measured in a signal processing circuit 12 from the detected signal and clock signals for measurement, and whether the switching operation of the spool is normal or abnormal is judged by comparing their operation time T1-T4 with a plurality of reference values T1a-T4a and T1b-T4b which were input in the signal processing circuit 12 beforehand, and an indication signal is output according to the results of the judgment.
    • 目的:根据从电磁阀检测出的运转时间判断开关动作是否正常,确定故障前电磁阀的异常情况。 构成:阀芯的行程端的位置由安装在电磁阀上的检测装置和阀芯移动开始时间检测,直到阀芯在电磁阀的驱动信号变为ON或OFF之后从行程末端开始运动 ,并且在信号处理电路12中根据检测信号和时钟信号测量到卷轴到达笔划末端的线轴移动完成时间,以及通过比较其操作时间来判断线轴的切换操作是正常还是异常 具有预先输入到信号处理电路12中的多个参考值T1a-T4a和T1b-T4b的T1-T4,并且根据判断结果输出指示信号。
