摘要： PURPOSE:To measure the osmotic pressure of a sample solution simply and quickly, by directly measuring the propagation speed of ultrasonic waves in the sample solution and the temperature of the sample solution. CONSTITUTION:A sensor section 2 is emmersed into a sample solution, an ultrasonic wave is transmitted from an ultrasonic transducer 4 and reflected waves from a passive reflector 3 received with the transducer 4 again. When the distance between the passive reflector and the transducer 4 is represented by L0 and the time to the transmission of the subsequent ultrasonic pulse after the reception of the reflected wave T0, the propagation speed V of ultrasonic waves in the sample solution can be calculated by the formula by measuring the time (t) spent in the repetition of the transmission by n+1 times. This information is inputted into a CPU12. On the other hand, changes in the voltage of a temperature sensor 5 are converted into temperature information with a temperature measuring circuit 9 to be inputted into the CPU12. The constant of a multi- degree polynomial for determining osmotic pressure of a sample solution with the temperature and propagation speed as variables is memorized in a memory circuit 13 and it is used to determine the osmotic pressure in the sample solution.

摘要： PURPOSE:To improve moisture resistance, in an ultrasonic wave sensor comprising an ultrasonic wave vibrator, a holder and a sealing material, by forming a film of a conducting or non-conducting material on the surface of the sealing material, and preventing the intrusion of moisture. CONSTITUTION:An ultrasonic wave vibrator 3 is stuck to a holder 2 by a bonding agent. The electrodes of the vibrator 3 are connected to terminals 6 and 7 by cables 4 and 5. The terminals 6 and 7 are fixed by a substrate 8. The upper part of the substrate is sealed by a sealing material 9. A thin film 10 is formed on the surface of the sealing material 9 and the like. The material of the thin film is a non-conducting material, which can be formed, by e.g., vacuum evaporation sputtering, ion plating and the like. SiO, SiO2 and fluorine resins such as polytetrafluoroethylene and the like are used. A cover is applied on the part of the terminals 6 and 7, which are protruded to the outside of the holder 2, so that a thin film is no formed, and the thin film 10 is formed. Thus the intrusion of moisture is prevented and the moisture resistance can be improved.
