If you want to measure rotation speed and with good accuracy, the ET-100 Engine Tachometer, with its pulse and analog output, can respond to this need.
Packed with all the capabilities of an engine tachometer, but can of course still be used as a tachometer for general FV conversion.
Conveniently built-in functions for engine revolution measuring
Apart from the ignition pulse detector (sold separately by our company), it is also compatible with various other sensors including gear sensors, proximity sensors, and photoelectric sensors.
Built-in high-speed response for F/V conversion output, pulse output, and USB output
■ Resolution per revolution
Measurements can be taken whether using both a piece of reflection tape to mark each revolution, or if there are 60 gear teeth.
Setting the number of pulses will display r/min data automatically.
■ Measurement data
As well as a digital display, analog (FV output) and USB data are also output.
Because USB data is output every 0.1s on a digital display, there is no lag between the display data and data on the PC.
■ Pulse output
The signal which is input undergoes wave shaping before output.
And simultaneously, a pulse is output once every revolution, or a half-frequency signal is output.
■ Power supply
The unit is driven by 9 to 32V DC. And an AC adaptor is supplied as an accessory.
■ Accuracy
Display accuracy of ±100ppm±1digit. High accuracy analog output (FV output) of ±0.1%F.S
■ Wide variety of functions
The input selects the AC/DC coupling, and many functions, including a moving average and pulse response delay, are then available as standard for improving the measurement.
