Title: Junji Kawachi: Innovator in Differential Pressure Measurement

Introduction

Junji Kawachi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of pressure measurement technology. His innovative work has led to the development of a unique differential pressure transmitter.

Latest Patents

Kawachi holds 1 patent for his invention of a differential pressure transmitter. This device applies respective measurement pressures to a pair of barrier diaphragms located on both side surfaces of a body. The movement of a sealed liquid caused by the differential pressure is converted into an electrical output by a differential pressure measuring pressure sensor. This sensor is partitioned within a sealing circuit. The design includes a sensor housing that is manufactured independently of the body. Additionally, the differential pressure measuring pressure sensor works alongside a static pressure measuring pressure sensor, which measures static pressure when a measurement pressure is applied to one of the barrier diaphragms and a reference pressure, such as atmospheric pressure, is considered.
