Page 15: Chapter 2 Function And Configuration
Chapter 2 Function and Configuration „ Overview The ALTJ9000 immersion type liquid level transmitter incorporates a microprocessor, uses a semiconductor pressure sensor to detect the water pressure, and outputs the cur- rent signal in proportion to the liquid level. This transmitter is composed of a probe and a junction box. -
Page 16: X84; Configuration
Chapter 2 Function and Configuration „ Configuration y Probe The probe, which consists of a pressure-receiving section and a transmission section, is installed underwater. The water pressure is transmitted to a semiconductor pressure sensor through a metallic diaphragm and sealed liquid. The transmission section processes the output of the semiconductor pressure sensor. -
Page 17: X84; Operating Principle
Chapter 2 Function and Configuration „ Operating Principle The pressure-receiving section transmits the water pressure through the metallic dia- phragm and sealed liquid to the sensor section. In the sensor section, the sensor deforms to a degree that corresponds to the transmitted pressure, and the resistance value changes. A Wheatstone bridge circuit detects the resistance and sends it to the transmission section after A-D conversion. -
