Pressure Sensor
Business Overview
Innovation from Measurement to Control
- Since 1983, have started the development, manufacturing, and sales of pressure sensors. They convert measurement values into electrical signals, shifting from traditional measurement to control!
- An instrument that converts the "pushing force" of air or liquid into electrical signals, requires driving power, and can send measurement data in real-time to monitoring and control systems. Recently, with the perspective of labor reduction, automation of equipment has progressed, and the quantity installed, and demand are increasing from the viewpoints of improving the accuracy of automatic control and enhancing safety.
Core Technologies
SS Sensor Semiconductor Strain Gauge Sensor
Medium to high pressureIn this semiconductor strain gauge sensor, a strain gauge is deposited by plasma CVD on a metallic diaphragm and on insulator film. This pressure sensor detects strain caused by the distortion of the diaphragm due to the pressure applied on this diaphragm from liquid, by means of measuring the change in resistance.
MS Sensor Metal Thin Film Strain Gauge Sensor
Medium to high pressureThe MS sensor uses a sputter-deposited metal thin film strain gauge as the strain gauge, and compared to the SS sensor, it is a medium-to-high pressure sensor that has both high stability and high electrical stress resistance and can function in higher temperature environments and environments with more noise.
CS Sensor Ceramic Thick Film Strain Gauge Sensor
Medium pressureThe CS sensor is a ceramic sensor in which a strain gauge and bridge circuit are formed on a ceramic diaphragm by thick film printing. Because the diaphragm itself is ceramic, it has excellent insulation and corrosion resistance and is a sensor module on which circuit components such as ASIC can also be mounted.
Enclosed SUS316L Sensor Stainless Steel Seal Diaphragm Sensor
Low to medium pressureThis is a diaphragm-type pressure sensor that has been oil-sealed between the sensor and the SUS316L diaphragm using the MEMS sensor die. This sensor is used for the low and absolute pressures, which detects a change in resistance of the strain gauge by transmitting the pressure received by the SUS316L diaphragm to the sensor die through the filled liquid.
CC Sensor Ceramic Capacitance Sensor
Low pressureThe CC sensor is a highly repeatable low pressure sensor which detects pressure by sensing capacity change between the electrode installed on the ceramic diaphragm and another stationary electrode at the other end.
SC Sensor Silicon Capacitance Sensor
Fine differential pressureThe SC sensor is a differential fine pressure sensor to detect pressure by change in capacitance between the diaphragm and the electrode. The silicon diaphragm is processed with micron-order accuracy on the cutting-edge micro-machining technology.
