QBJ-3C
Intelligent Smart Speed Measuring Instrument Single, Double Channel Digital Speed Indicator AC 220V
Jiangyin No. 3 Electronic Instrument Co., Ltd.
Summary
QBJ-3C smart rotating speed measuring instrument with CS-1 type magnetoresistive sensor for rotating mechanical speed measurement.The instrument is the use of high-end single chip microcomputer to form speed measurement system, in the design of the computer and instrumentation com., and insufficient attention to hardware and software combination of play software programming, flexible, variable features, and the measuring range and alarm value setting arbitrary function, can satisfy 1 slot or groove, 60 tooth, 3 48 teeth, 30 teeth of different measured conditions, speed alarm function, alarm function, users can according to different conditions to select the most suitable function.The instrument has the advantages of convenient use, high reliability, with soft, the hardware watchdog circuit is the measurement of speed of the new generation of instrumentation, it is suitable for steam turbine power plant, industrial steam turbine, water pump, fan speed measurement requirements.QBJ-3C smart rotating speed measuring instrument can be divided into the panel and wall hanging type two kinds, for the user to choose
