日本COCORESEARCH  TDP-3921-R 周期速度计 测速计  原装

A special tachometer, TDP-3921-R, is the first choice of Japanese car industry due to its unique functions. It offers two channels photo MOS relays output and RS-232C high-speed communication. Above all, it has unique optional functions like BCDand analog output with an ideal response time of1ms.Its measurement range is from 0.0006Hz to 100kHz with a programmable display to read out in terms of wide range of units like rpm, rps, Hz, km/h, l/min, g/h, etc. 


Features
High speed analog output

The measured value can be transmitted as -10 to 10V analog signal (0 to 10V when input is single phase pulse) to other devices / system such as data logger or PLC. The polarity of analog output follows the direction of rotation of pulse generator. The analog signal can be scaled, e.g. 0 to 10V = 0 to 8000rpm. Where as the updating time is 1ms.

Wide range


Input frequency range is 0.0006Hz to 100kHz without any change in range. The display accuracy is 20ppm±1digit.

Employing PERIOMATIC technology


The forecast computation PERIOMATIC, versatile software, is the principle of working of TDP-3921-R. It enables the user to get analog output voltage even in the presence of heavy fluctuations. The PERIOMATIC has stop (zero speed) forecasting function, so the TDP-3921-Rimmediately responds to sudden stop of the incoming pulses.

Compatibility to variety of Inputs

The TDP-3921-R can directly be connected to varying sensors like AC magnetic pickups, rotary encoders, proximity sensors, and pulse output devices. The TDP-3921-R can detect the direction of rotation of pulse generators and indicate it by minus or plus sign on LED display and analog output when phase signals are applied.
Large 14.2mm bright LED display with fixed or floating decimal point
Three kinds of averaging function, time average, moving average, and pulse dividing average are used to dealt with irregular and heavily laden with fluctuation incoming pulses.
It offers independent and programmable updating times of display and analog output
