New ! CT-6700 Multi - Application Engine Tachometer
Universal Tachometer
Date: 03/11/2019

CT-6700 - ( New ! ) Universal Digital Engine Tachometer
The CT-6700 is a digital engine tachometer that measures the revolution speed of gasoline, diesel engines, and motors (EV/HEV) equipped on electric vehicles or hybrid electric vehicles or general rotating bodies. This compact tachometer supports 10 kinds of sensors with different usages and purposes including ignition pulse detector, gasoline and diesel engine rotation detector, and magneto-electric rotation detector. We are now able to measure engine rotation speed by ECU crank signal even when it is difficult to mount a detector on an actual vehicle.


High response measurement- Analog output response 1 cycle +8 us or less of input signal The CT-6700 catches transient phenomena of engine rotation speed with high response. The analog output follows up the behaviors of acceleration/deceleration within 1 cycle + 8us of input signal. As for pulse output, waveform-shaped output can be selected for signal output of engine rotation speed without delay.

Supports various sensors with different purposes. In addition to 10 kinds of detectors such as an ignition pulse detector, gasoline/diesel engine rotation detector, magneto-electric rotation detector, ECU crank signal output becomes available. The CT-6700 measures rotation speed of various engines which is undetectable so far.

Automatic setting of trigger level with the Trigger Assist Function. Before engine rotation measurement and motor rotation measurement, a trigger level is adjusted. Especially for the measurement using ignition signal, it is important to remove noise influence for stable measurement. This function performs trigger level adjustment automatically and helps to reduce setting time.

Measurement by ECU crank signal of unequal interval pulses (option: CT-0672)The CT-6700 enables rotation measurement by input of ECU crank angle signal. Since gear teeth are arranged at unequal intervals for top dead center detection, ECU crank signal is detected as unequal interval signal. The CT-6700 learns pulse pattern at unequal intervals and makes stable measurement even by input of ECU crank signal.

High speed digital data output by CAN* interface option: CT-0671 * CAN: Controller Area Network

When using the CT-6700 in combination with an Ono Sokki detector, rpm measurement can be performed on virtually any engine type. The CT-6700 is used for research and / or production measurement of rpm on gasoline & diesel engines (two / four cycle engines having from one to eight cylinders) or component shafts.
With a measurement range of 0 to 99,999 r/min., the CT-6520 uses a 5-digit large green LED to display the actual rpm being taken.

Powered by both AC and DC, the CT-6700 can be used in the lab, on the production line, or during in-vehicle testing.

A variety of detectors and detection methods support measurement on virtually
any engine type (or other rotating bodies). This tachometer will meet all of your
engine rpm measurement demands, whether your rpm application calls for:

An ignition pulse detector that clamps around the ignition coil to detect the spark
signal of the ignition system,

Using an electromagnetic detector that measures rpm on engines having a
magneto-type ignition system,

Photoelectric sensor used to detect the presence of a reflective mark affixed to a
rotating part on an engine.

Magneto type vibration detector that detects the vibrations caused by a
reciprocating up and down movement of the piston,

Or a magnetic detector mounted near a gear attached to a rotating shaft, and
output signal having a frequency proportional to the rpm.

Pulse, analog, and digital outputs are provided as standard, to interface to
recorders, spectrum analyzers, computers, or other data acquisition systems.
