摘要： PROBLEM TO BE SOLVED: To provide a small-sized pressure sensor with a wide fluid pressure measurement range.
SOLUTION: This pressure sensor comprises a diaphragm 21 having a peripheral edge part fixed in a case 10 and deformed by a fluid pressure given to at least one side, and a signal conversion part 40 for converting the deformation of the diaphragm 21 into an electric signal. The conversion part 40 comprises an oscillation circuit formed of a print coil 46 printed on one side of a printed circuit board 45, and the print coil 46 confronts the diaphragm 21 at a prescribed distance.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic liquid level detecting device capable of applying a predetermined pressure at all times to a transmission/reception surface of an ultrasonic oscillating element to bring it into contact with a metal container. SOLUTION: The transmission/reception surface of a sensor holder 30 housing the ultrasonic element is held in a case main body 10 so as to reciprocate in directions which intersect each other approximately at right angles. In addition, the sensor holder 30 is pressed to the side of the metal container by the spring force of a coil spring 22.
摘要翻译：要解决的问题：提供一种能够一直施加预定压力到超声波振动元件的发送/接收表面以使其与金属容器接触的超声波液位检测装置。解决方案：容纳超声波元件的传感器保持器30的发送/接收表面被保持在壳体主体10中，以便在大致成直角相交的方向上往复运动。此外，传感器支架30被螺旋弹簧22的弹簧力压到金属容器的侧面。
