Elevator speedometer

EC-2100

The elevator speedometer EC-2100 is a compact, lightweight, battery-operated handheld speedometer designed for the adjustment, maintenance, and inspection of elevators. Compared to the conventional model (EC-900), the measurement range has been doubled (up to 2000 m/min), and the calculation time has been shortened to 1/10 (10 ms), making it suitable for measuring the speed of high-speed elevators and rotational measurements.

By simply pressing the peripheral speed ring lightly against the elevator's wire rope, easy and accurate measurements can be performed. The display uses a highly visible red LED, allowing measurement values to be easily read even in dark places. Additionally, by securing the EC-2100 body to a fixture or using an external detector (EC-0201 optional), inspection work can be carried out by a single person.

The EC-2100 can hold measurement values not only through the main body’s push-button switch but also via external contact signal input, allowing for safer work without being distracted by the display during measurement. Two displays hold and show two-stage measurement values.

By adding the distance measurement function EC-0202 (optional), it can be used as a handheld distance meter to measure the distance (mm) traveled within a specified time, and by adding the distance measurement function EC-0202 (optional) and trigger device (EC-0203 optional), it can also be used for measuring the emergency stop distance of escalators.

Inquiry

The measurement range is up to 2000 m/min, with a minimum calculation time of 10 ms, enabling high-speed speed and rotation measurement.
The memory function allows saving a maximum of 10 sets of data.
Standard equipment includes analog output and pulse output.
The maximum value hold function holds the maximum value during measurement.
The averaging function averages speed and rotational speed measurement values (the number of averages can be set between 1 and 200).
Auto power off, battery level display function
The distance measurement function EC-0202 (optional) measures the distance traveled within a specified time (the sign can be set arbitrarily in relation to the direction of rotation).
Remote measurement is possible with the external detector EC-0201 (optional).
By attaching the optional rotating contact element KS-300, it can also be used as a contact-type handheld tachometer.

The speed is measured by pressing the speed ring against the governor's pulley or rope. By pressing the hold switch on the main unit [1][2] or using an external hold signal, the speed data at that moment can be measured and displayed independently.

Maximum Value Measurement
By pressing the [DISP] switch on the main unit, the maximum value being measured is displayed on the lower screen. Maximum value hold measurement is possible.

Memory Function
The measured values are saved in the main unit. When measuring rotational speed (m/min, r/min), CH 1, CH 2, and MAX values are saved. When measuring distance (mm), the measured value, sign, and rotation direction are saved. Data saved in setting mode can be read out from the [MENU] switch.

When using the Trigger Device EC-0203 (optional)

Connect the terminals of the trigger device to the escalator and the connector to the elevator speedometer (EC-2100). When the button on the trigger device is pressed, the escalator will stop emergency operation, and the measurement of the elevator speedometer will begin. After the measurement is completed, the measurement value will be held for 2 seconds to prevent miscounts.
When not using the trigger device.

Measurements can be started and stopped by pressing the hold switch on the main unit.

Measurement (Distance Measurement Function EC-0202)

The peripheral speed ring is pressed against the object for measurement. The timing for starting and stopping the measurement is done with the main unit's switch. The rotation direction can be set, and it supports count up and down. After the peripheral speed ring stops, the value will automatically hold after 2 seconds (auto-stop function) ^※ 1.

※1 The auto-stop function can be disabled by modifying the EC-2100 main unit.
