Abstract: A demand for downsizing of a multiple optical-axis photoelectric sensor can be coped with, and various state displays are performed.An inter-optical-axis indication unit is arranged between two adjacent optical axes so as not to interfere with the optical axis located in a lower end portion of a receiver. The inter-optical-axis indication unit is capable of displaying at least one piece of information out of a control input state, a safe special function state, a synchronization type, and an interlock state.

Abstract: Provided is an ultrasonic flow switch which can be stably mounted on pipe. A clamp part is mounted on an outer surface of the pipe. A casing part which integrally or independently holds the first and second ultrasonic wave elements is fixed to the clamp part by a sensor fixing screw. The clamp part is configured to restrict displacement of the casing part in an axial direction of the pipe and in a circumferential direction of the pipe and to allow displacement of the casing part in a radial direction of the pipe in a state where the casing part is not fixed.

Abstract: To add a function of detecting a temperature to an ultrasonic flow sensor without making the structure of the ultrasonic flow sensor complicated. A sensor portion of the ultrasonic flow sensor includes an acoustic coupling member. The sensor portion includes a heat transfer member having a heat detecting surface for detecting heat of piping. The temperature of heat transferred in the heat transfer member via the heat detecting surface is detected by a temperature detecting device. The heat transfer member restricts an amount of collapse of the acoustic coupling member in a radial direction of the piping when the sensor portion is fixed to the piping.

Abstract: Provided is an ultrasonic flow sensor with improved practicality. An ultrasonic wave is transmitted and received by an ultrasonic element. A first flow rate value of a fluid in a pipe is calculated based on a propagation time difference of an ultrasonic signal, a measurement value corresponding to an ultrasonic velocity, and a parameter for identifying an inner diameter of the pipe. A second flow rate value of the fluid in the pipe is calculated based on a frequency shift of the ultrasonic signal and the parameter. The first flow rate value is calculated using a propagation time of the ultrasonic signal as the measurement value in accordance with a correspondence relationship among a distance of a path through which the ultrasonic wave propagates through the fluid in the pipe, a time for which the ultrasonic signal propagates in the path, and the ultrasonic velocity.
