Patent JP-H03261868-A (JP)
Title: Flow sensor
Inventor: NASA HARUHIKO
IPC: G01P5/12
Filed: 1990-03-12
Abstract: PURPOSE:To accurately measure flow velocity by improving sensitivity and widening the control range of the angle to the flow of gas by forming the first and second thermometric resistors to the support film part built over the V-groove piercing both side surfaces of a semiconductor substrate. CONSTITUTION:Voltage is applied across the electrode terminals 4a, 4b of the flow sensor and a current is supplied to a resistor 4 to generate heat. Since a support part 2a is composed of a membrane, the temp. thereof rises by slight electric power and becomes higher than that of a Si substrate 1. The resistance value of a resistor 5 changes corresponding to this temp. change and the voltage between the electrode terminal 5a, 5b changes. When the sensor is placed in a fluid whose flow velocity must be measured, the heat diffusion quantity per a unit time from the membrane 2a changes corresponding to the flow velocity and the temp. thereof falls or rises. Therefore, the resistance value of the resis tor 4 is increased and decreased corresponding to temp. change and outputted as the increase and decrease of the voltage between the terminal 4a, 4b. Next the resistor 5 detects the temp. or circumferential temp. of the Si substrate 1 and, when a constant current is allowed to flow to the resistor 5, the output voltage proportional to the biquadratic root of flow velocity is obtained.
