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.

Abstract: Provided is a level meter that allows a user to easily visually grasp a relative position of a threshold with respect to a container when the user sets a threshold of a level. The display portion of the level meter displays a bar display whose length expands and contracts according to the value of the level of the object stored in the container. In addition, the display portion displays a relative position of the plurality of level setting values related to the level with respect to the container together with the bar display.

Abstract: Provided is a level meter with which a user can easily visually grasp a state of a level of an object to be measured. The level meter includes a sensor unit, a housing, and a display unit. The sensor unit is disposed on one end side along the measurement axis and measures a level along the measurement axis. The housing is disposed on the other end side different from the one end side of the measurement axis. The display unit is provided in the housing, and displays the level measured by the sensor unit with respect to the color graph together with the color graph having a plurality of level ranges color-coded with different colors.

Abstract: Provided is a level meter capable of correctly measuring a level of an object stored in a container. The level meter includes a distribution determination unit, an extraction unit, a candidate determination unit, and a display portion. The distribution determination unit determines the reception intensity distribution of the reflection signal with respect to the distance from the level meter based on the reception intensity of the reflection signal due to reflection of the measurement signal. The candidate determination unit extracts a plurality of combinations of the peak position and the peak intensity from the reception intensity distribution by the extraction unit, and determines the combinations as a plurality of peak candidates. The display portion displays a candidate confirmation screen including the measurement value corresponding to each of the plurality of peak candidates and the reception intensity scale related to the reception intensity.

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.
