Abstract: A pressure sensor includes a joint portion, and a shock mitigating member including therein a flow path communicating with a branch path. The shock mitigating member includes a first flow path configured to cause a fluid to linearly flow, a blocking wall configured to block the fluid from linearly flowing, and a second flow path communicating with the first flow path and configured to cause the fluid to flow in a direction different from an axial center of the first flow path. Further, the shock mitigating member includes outlets with which the second flow path communicates, and a gap for adjusting a pressure of the fluid is formed between the shock mitigating member and the joint portion.

Abstract: A pressure sensor is equipped with a body including a fluid passage in the interior thereof, a holder connected to one end of the body, and a ceramic sensor accommodated in the interior of the holder. Plural protrusions are disposed on an outer edge portion of an end surface of the sensor, which is pressed by the holder. In addition, when the holder is fastened with respect to the body, in a state in which a pressing portion of the holder abuts against the protrusions, a fastening force is applied in an axial direction, and the sensor is fixed.

Abstract: A pressure sensor includes a ceramic sensor that is accommodated between a body and a holder. On an end surface of the sensor, plural resistive bodies are printed and fired in a straight line using a thick-film resistive paste material by screen printing.

Abstract: Each of pressure-detecting switches to be connected to one another has a first connector provided at one side section and a first connector provided at the other side section. Electric wiring is mutually effected for the pressure-detecting switches by attaching/detaching the first connectors. The pressure-detecting switches are mutually fixed by using a fixing mechanism arranged for the side sections to effect the function for mutually attaching/detaching the pressure-detecting switches.

Abstract: A liquid level detecting and indicating system for detecting a liquid level of a measured object such as fuel on the basis of a resistance changed in accordance with level variation of the measured object and indicating the liquid level in response to a magnetic field produced to correspond to the resistance. The system comprises a gauging circuit coupled through a switch to a battery and including a bridge circuit comprising at least a variable resistor and two groups of coils, the variable resistor being arranged such that its resistance is changed in accordance with the level variation of the measured object. Also included in the system is a disturbance detecting circuit coupled to one end of the variable resistor of the gauging circuit for comparing the voltage thereof with a reference to detect a abrupt variation of the voltage at the one end of the variable resistor and generating a control signal in accordance with the result of the detection.
