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