Abstract: A worker is prevented from being hindered. A safety switch includes a switch body including an electromagnet and an actuator attracted to the electromagnet. The switch body includes a drive control unit and a safety control unit which control the safety switch, and the drive control unit and the safety control unit are surrounded by a housing. The housing is arranged on a back surface side of the electromagnet of the switch body, and the housing forms an accommodating portion that accommodates the drive control unit and the safety control unit.

Abstract: Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.

Abstract: Provided is an optical safety system that enables simplification of an editing operation for area designation information. A safety scanner includes an intrusion sensing section that determines the presence or absence of an intruder into a protection area. The setting support device includes a pseudo determination information generation section that determines a presence or absence of an intruder into a protection area on the basis of an area designation information before being transmitted to the safety scanner and a distance measurement information received from the safety scanner and generates a pseudo determination information indicating the determination result.
