Toky Frequency Meter

FI SERIES

FREQUENCY / SPEED / LINE SPEED METER

• The 6-digit digital tube displays that the upper row shows the measured value and the lower row shows the alarm set value;
• Two output control modes are available: upper limit alarm (U) and lower limit alarm (d);
• Have a hysteresis setting to improve the stability of the instrument and system work;
• Select 4-20mA transmission output and RS485 communication interface;
• High measurement accuracy, optional fixed point or floating display;
• Multi-purpose instrument: It can be used as frequency meter, line speed meter and tachometer respectively through software selection.

FM FREQUENCY METER

• Thumb switch setting alarm value, 4 control mode: U-U, U-d, d-U, d-d.
• The frequency/tacho/linespeed measuring function selected by software.
• Input/output optoelectronic isolation,high anti-interference.
• The display refreshing rate can be set accoding to customer’s viewing habits.
• Frequency range of the input pulse is settable.
• High accuracy, decimal point is optional for float or fixed display.

FA FREQUENCY METER

• Pulse signal/high-voltage industrial frequency signal input.
• Frequency/line speed/tacho measuring is selectable.
• One alarm relay output function.
• Input signal is specially filtered, which improves anti-clutter ability.

DM FREQUENCY METER

• Frequency meter is the instrument which receive the pulse signal from the sensor, and reappear the live mechanical equipment running speed by internal processing operations,thus to achieve the protection of field devices by its included output function. And it is widely applied on the instruments’ running status monitoring and operation speed controlling.
• Ultra-thin design,delicate size,easy to install.
• High accuracy, good performance.
• For measuring frequency/tacho/counting.
• Decimal point floating display.Will display the fractional values accoriding to available space next to the last digit from the left.
