1. Industrial Sensor Networking Technology for Improvement of Manufacturing Equipment Effciency
Susumu Nishisaka
To improve overall manufacturing equipment precision and efficiency, Azbil has developed its K1G-C04M high-precision position sensor controller, which is compatible with the MECHATROLINK-Ⅲ open filed network. In this product, a problem involving previous analog output position sensor controller models was solved, and sensor instrumentation was optimized to measure at a rate of up to 250 μs and a resolution of 0.1 μm. At the same time, the constant periodicity, high speed, and communication monitoring of MECHATROLINK-Ⅲ made the controller compatible with manufacturing equipment with higher demands for reliability.
2. A New Pressure Sensor Structure with Minimal Enclosed Oil
Tatsuo Tanaka
We have developed a pressure sensor structure for small pressure transmitters that we believe will benefit process automation, factory automation, and various markets such as the sanitary market. The pressure sensor structure is equipped a new pressure sensing element with built-in overpressure protection. The new pressure sensing element has a pressure introduction chamber both on the top and the bottom of the pressure detector, and contains only a very small amount of enclosed oil as the pressure transmission medium. Minimizing the amount of oil minimizes the degradation of characteristics caused by the ambient temperature, allowing higher precision. The amount of enclosed oil is reduced to less than 10 % compared with the existing structure.
