製品写真(SE-1620ガソリンエンジン回転計)

The SE-1620 is an engine tachometer that performs measurement of the number of revolutions of a gasoline engine by connecting an engine revolution sensor such as an ignition pulse detector. A 100-mm wide-angle meter is used for the display, and both analog output and pulse output functions are provided as standard.

Simply attach an ignition pulse detector or one of our other compatible detectors to the engine to enable measurement of the number of revolutions of a gasoline engine. The inputs, outputs and input power supply are all isolated to ensure the output of analog and pulse signals with superior noise resistance and stability characteristics.

 

Features

  • Applicable for the input signal of various detectors or ECU rotational pulse by 5V line
  • Input signal is optimized depending on the engine spark system or used detectors by signal sensivity selection switch.
  • Easy reading thanks to 100 mm wide angle meter
  • Convenient on vehicle or field measurement by DV12V or 24V power
  • Function of analog/pulse output are provided as standard.
