Device BTT-500 (btt500, bt 500)
Device BTT-500 is designed to measure the strength of the trailer hitch vtalkivaniya range from 0H to 5000N with an accuracy of ± 2%.High accuracy of measurements provides a quality strain gauge sensor.
Nagruzhatel drawbar trailers used during the inspection (tehkontrolya) cars to measure the effectiveness of an inertial brake trailers.
Nagruzhatel trailer hitch does not need a compressor and delivered ready to use.
Indication of measured values is carried out on the digital display in Newtons (no need to make an indirect translation of the pressure in the value of the force).
For the convenience of the operator provides the maximum viewing of the measured values of the force vtalkivaniya hitch trailer.
Device BTT-500 provides a rigid connection to the forkopom car and trailer coupling device.
Technical characteristics of the Devices BTT-500:
Measuring range - 0H-5000N;
Measuring step - 1H;
The accuracy of measuring the force vtalkivaniya coupling the trailer:
- From 0H to 1000H - no more than ± 20N;
- From 1000H to 5000N - no more than ± 2%;
The measuring element - the load cell;
Ambient temperature - 0 º C to 40 º C;
The principle of the device is to measure the force with which the tension acts on the lever of the brake mechanism of the trailer. The force with which the contracts trailer brake is measured by two sensors that are mounted on the car and trailer with built-in load cells. The countdown is displayed on the display;
Device BTT-500 consists of a lever of the tension brakes of the trailer, the opening mechanism for the tension force gauge, mounting mechanism on the trailer, the mounting mechanism by which the device is attached to the trailing hook;
The buttons on the measuring unit:
- On / off the device;
- Zero calibration device;
- Button to save the maximum readings, and to change the units of measurement;
The meter provides an easy readout of the measured force;
Power measuring unit - 6 standard AA batteries or rechargeable batteries;
Battery status measuring unit nagruzhatelya trailer hitch shown in percentage on the display.The inscription BAT LOW means that the battery is discharged, and the measurements may be incorrect. In this case it is necessary to replace batteries or recharge the batteries;
Measurement of force vtalkivaniya trailer hitch with the trailer hitch nagruzhatelya:
A. Before the test, to eliminate or minimize the factors that influence the outcome of the study (in the case of trailers with two axles to pull the wheel);
Two. Before connecting the roller mechanism to unhook the trailer from the car. Then bring the trailer back to the car at a distance of 0.5 m;
Three. Fasten the bracket to the trailer ball apparatus;
4. Support the trailer, using the tension level the instrument;
Five. Toggle the switch on the spade trailer hook and fasten the bottom of the device special hooks. Then use a screwdriver to tighten the chain;
6. The device hooks to catch the ball and lock the car with a screwdriver;
7. Enter the study on the axis of the tester to diagnose the effectiveness of the brakes;
Eight. Hook hook on the tensioning pass element in the construction trailer so that the belt was in the trailer axle;
9. The free end of a pass in front of a split shift at the end of the arm stretching, and then through the pulley mechanism for tightening lever to catch them for a hook on the bottom of a car or other stationary object of a car that is on the axle of the trailer;
10. Set the lever to be parallel to the axis of the trailer and then pull the pass through mechanism for tensioning levers;
11. Turn on and throw on the "0" gauge;
12. Insert the stand on the brake hand brake force measuring device;
13. After the start of the measurement through the video slowly pull the lever, causing the brake is tightened at the time of achieving power, equal to 10% by weight of the trailer. The display shows the present time, the force with which the brake is drawn to the pull mechanism;
14. In the case of multi-axis measurement procedure to trailers for each axle, complete with brake;
The manufacturer guarantees the quality of the instrument Device BTT-500 with the technical specifications in compliance with the conditions of the consumer terms and conditions of storage, transportation, installation, operation, established specifications and operational documentation;
