ONOSOKKIDual-channel multi-function digital speed indicatorTM-5100This is a two-channel digital tachometer that receives independent rotation signals from two rotating bodies, calculates and displays the respective rotation speeds, speed ratios, and speed differences. The input signals of each channel can be corrected with independent coefficients, which can be set arbitrarily from 0.0001 to 99.999 times. Therefore, in addition to the rotation speed, it can be converted into any physical quantity depending on the object to be measured and the purpose. For example, it can measure the speed ratio and speed difference of the conveyor line, as well as the parameters on the production line such as the reduction rate (elongation), tension rate, and slip rate in the pressing and rolling process of steel plates, papermaking, and aluminum plates. In addition, if independent upper and lower limit comparators are set in each channel, the rotating body can be monitored and controlled. According to the different purposes and usage environments, our company also has a large number of electromagnetic, magnetoelectric speed sensors and photoelectric sensors, rotary encoders, and TM-5100 tachometers, which can be used in conjunction with the TM-5100 tachometer to build a suitable measurement and control system. It can calculate and display the signals from the two rotating bodies. Using the independent coefficient correction function for each channel, it can be converted into any physical quantity proportional to the rotation speed. Built-in comparator function with 2 upper and lower limits Using dual-channel calculation function, it can display speed difference, speed ratio, pressing rate, slip rate, change rate ((B - A)/A), speed direction* The speed range is large, from low speed to high speed (input frequency: 0.6 MHz to 100 kHz) The price is low, about 1/4 of the old model (such as QW-163B) As an output function, it has BCD code, analog signal, and comparator. The standard interface RS-232C is easy to install. The size is in accordance with DIN specifications (144 × 72). It adopts two display parts: the main display part that displays the count value and the auxiliary display part (2 segments) that can display the setting items (comparison setting value, coefficient value, etc.) Supporting sensors MP series electromagnetic and magnetoelectric sensors, LG series photoelectric sensors, RP series rotary encoders, etc. manufactured by our company Input impedance 10 kΩ or more (at 100kHz) Number of input channels Dual channel input Amplification type AC/DC (switchable) Measurement method Periodic calculation method: Gate calculation method (switchable) Speed direct reading calculation function Coefficient setting range: 0.0001 to 99.999 Dual channel calculation function Difference <B - A>, ratio <(B / A) x 100>, change rate <(B - A/A) x 100> Rotation direction measurement function When using a two-phase rotary encoder, the rotation direction is displayed using a polarity display Main display Green 7-segment LED Display range: 0 to ±999999 (0.00 to 9999.99%) Sub-display LCD module display characters 16 characters × 2 segments Signal input input impedance: 10 kΩ or more (at 100 kHz) AC (alternating current) amplifier Signal waveform: Sine wave or rectangular wave Signal voltage range: Sine wave 0.2 to +45 Vrms, rectangular wave 0.6 to 63 Vp-p Signal frequency range: 1 Hz to 100 kHz DC amplifier Signal waveform: Rectangular wave signal with a pulse width of 4 μs or more Voltage range: Hi level +4 to 30 V, Lo level -1 to +1 V Signal frequency range: 0.0006 Hz to 100 kHz Number of comparator function setting steps: 2 steps Range: 0 to ±999999 Output item: UPPER/GOOD/LOWER Output form: Semiconductor relay contact (DC 30 V, 0.1 A) Analog signal output conversion method: 12-bit D/A method Voltage range: 0 to ±10 V/FS (FS is full scale, can be set arbitrarily) BCD output positive and negative logic (switchable), 6-bit parallel Output form: Open collector output RS-232 output baud rate: 2400, 4800, 9600 bps Sensor power supply DC 5 V ± 0.25 V (max. 150 mA) Total DC of A and B channels 12V ± 0.6 V (max 150 mA) Power supply for each channel A and B AC 100 V ~ 240 V 50/60 Hz 45 VA Operating temperature range 0 ~ 40℃ Operating humidity range -10 ~ 55℃ Humidity range up to 95% (but no condensation) Dimensions 144 (W) × 72 (H) × 180 (D) mm Weight Approx. 1.5 kg
