Elevator Speedometer
EC-2100
It enables easy and accurate measurement only by pressing the circumferential ring lightly to an elevator pulley or a handrail of an elevator. Measured value can be easily read on the red LCD even in a dark place. The operator can do an inspection alone by fixing the EC-2100 main unit by a jig or using the EC-0201 external detector (option).
As well as the buttons on the main unit, the measurement values can be held by the external contact signal. The each instantaneous value is displayed on the main unit. It supports more safety work without worrying about the displayed values.
Distance measurement is available by the EC-0202 (option). It measures moving distance within the specified time. Moreover by adding the EC-0202 (option) and the EC-0203 (option), the EC-2100 can measure actual moving distance of an escalator after emergency stop operation.
Features
Speed measurement of an elevator
Make a measurement by pressing the circumferential ring to a pulley of governor or a rope. The instantaneous value of each channel is displayed by using a hold switch [1] [2] on the main unit or using the external hold signal.
1.Maximum
value measurement
The maximum value during measurement can be
held and displayed on lower screen by [DISP]
button.
2.Memory
function
The EC-2100 has memory function to store the
measurement results to the main unit.
The data of CH1, CH2 and MAX value are stored in
rotation measurement (m/min, r/min), and the
measurement channel, plus/minis and rotation
direction in distance measurement (mm). The
stored data can be read by [MENU] switch.
Moving distance measurement after emergency stop
operation
(Distance measurement function: EC-0202, option)
Example of measurement results When a leftward movement of a handrail is set as +
Moving distance after emergency stop can be measured by pressing a circumferential ring to a handrail. Plus/minus display shows the rotation direction.
1.Measurement
using the EC-0203 trigger unit (option)
Connect the EC-2100 to an escalator via the
EC-0203 trigger unit. Pushing the trigger button
brings the escalator to the emergency stop and
the speed measurement is started. When two
seconds have passed after the measurement ends,
the EC-2100 holds the measurement result and
prevents miscount.
2.Measurement
not using the trigger unit
The hold switch [1] [2] on the main unit starts
and stops measurement.
Outer/inner perimeter measurement
(Distance measurement function: EC-0202, option)
The EC-2100 Elevator speedometer can be used as the handheld distance meter by installing the EC-0202 distance measurement function. The moving distance can be measured and displayed by pressing the circumferential ring to the measurement object. Start and stop are operated by the switches on the main unit. When the circumferential ring passes the stop position, the rotating direction setup enables correct measurement. The auto stop function* of the EC-2100 holds the measurement result when two seconds have passed after the movement of the circumferential ring ends.
*The auto stop function is disabled by the modification of the EC-2100 main unit.
