TDP-3921-R Periomatic Tachometer

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 BCD and analog output with an ideal response time of 1ms.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-R immediately 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 2 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
