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 optical displacement sensor that allows a housing serving as a head to be downsized. A relay cable extending from the head is integrated with a body. The head is primarily responsible for projecting and receiving light to and from a to-be-detected object, while the body is made up of a power supply circuit, a display, and an operation part. The head includes a green laser light source and emits the green laser light to form a spot on a surface of the to-be-detected object.
