Title: Takehisa Hataita: Innovator in Pressure Sensor Technology
Introduction
Takehisa Hataita is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of pressure sensor technology, holding a total of seven patents. His innovative designs have advanced the capabilities of pressure measurement in various applications.
Latest Patents
One of Hataita's latest patents is a pressure sensor with reduced deviation of temperature distribution. This pressure sensor comprises a diaphragm, an electrode body, a housing, an inlet pipe, and a thermal buffer member. The diaphragm features a pressure receiving surface that is designed to receive pressure from a measured target fluid. The electrode body includes an electrode surface that faces the rear surface of the pressure receiving surface, with a gap in between. The housing supports the diaphragm, forming a measuring chamber that surrounds the pressure receiving surface. The inlet pipe is connected to the housing, guiding the measured target fluid into the measuring chamber. The thermal buffer member, located on the inlet pipe, possesses a predetermined heat capacity, ensuring that the diaphragm remains stable and does not bend due to rapid temperature changes in the fluid line.
Another notable patent is the pressure type flowmeter. This invention addresses issues encountered in capacitance type pressure sensors that measure absolute pressure, thereby reducing measurement errors. The pressure type flowmeter includes a fluid resistance part within the flow path, which measures the flow rate by detecting upstream and downstream pressures. The respective pressure sensors for these measurements are configured as gauge pressure sensors. Each gauge pressure sensor is a capacitance type sensor that measures gauge pressure by detecting changes in capacitance between a diaphragm and a fixed electrode. The design includes a main body that supports both the fixed electrode and the diaphragm, creating a space between them that connects to the outside.
