Product function:
This instrument can realize on-site online detection of the balance coefficient of various elevators under no-load conditions; it can detect machine room-less elevators and steel belt elevators, and there is no need to select the control mode. It can detect various elevators with VVVF and worm gear control modes.
Performance characteristics:
The balance coefficient test can be completed by running the elevator up and down once (in no particular order). The balance coefficient is calculated by default based on the last two up and down data, and the last data is automatically replaced;
The host is equipped with a switch to prevent misjudgment or a switch to prevent misjudgment;
It has its own system setting function. Before the test, the printer connection and print test are set, and the port setting and configuration information are configured to facilitate the on-site inspection of the instrument, link, signal interference, etc.;
It can detect permanent magnet gearless traction machine elevators, worm gear traction machine elevators, and machine roomless elevators;
The measurement interface can display the up and down power change curve of the traction machine in real time;
The measurement data displays the voltage change value, current change value, operating power value and total power value during the operation of the elevator in real time;
The measurement results include: 1) The midpoint power and balance coefficient of the up and down of the permanent magnet gearless traction machine elevator. 2) The worm gear traction machine elevator is unloaded, Downstream midpoint power with load, balance coefficient;
This instrument is designed in accordance with the IEC61010-1 safety standard, and the safety specification is referenced as Saftey Class I regulations;
The instrument uses a 32-bit ARM microprocessor and a high-speed and high-precision A/D converter as the core instrument. It has high-precision, high-stability, and multiple parameter measurement functions, and is equipped with USB communication function;
The instrument automatically amplifies and collects signals, automatically processes the range, and is composed of anti-aliasing low-pass filter circuits;
The speed measurement module uses a 3D-MEMS acceleration sensor with independent configuration, and the cross-axis sensitivity and lateral vibration sensitivity are 1%;
The measurement host is equipped with a 0.87-inch small LCD screen, which displays the three-axis acceleration and power display percentage in real time;
The speed measurement process is completed in the car, and the numerical changes in different sampling points can be analyzed through the curve chart, vibration automatic monitoring, resonance frequency 2.4KHz, bandwidth (3DB) 500Hz;
