The PIAB RTM Rope Tension Meter is very simple and handy to use. Simply hold and “clip” it to the rope to be tested and use the large hand screw to deflect the rope to a fixed angle. The resultant force will affect the load cell and measure the tension in the wire rope. The resultant signal is digitally processed and displayed in a selected pre programmed graduation. The PIAB RTM 20D can be graduated in kN, klbs or in ton.

Измеритель натяжения тросов PIAB RTM прост и удобен в обращении. Для проверки просто закрепите его на тросе и используя винт-зажим натяните трос до фиксированного угла. Замер натяжения будет производиться вследствие давления результирующий силы на датчик нагрузки. Сигнал будет обработан и отображен в выбранных единицах измерения. PIAB RTM 20D может быть настроен в  кН, klbs или тонах.

The PIAB RTM 20D was designed to swiftly and accurately measure the tension in fixed or stationary ropes or cables i.e. guy wires for masts and towers or other guyed constructions. The PIAB RTM 20D will also be very useful in determining the tension in overhead suspension ropes for railway catenaries.

The PIAB RTM 20D can be used to measure tension forces up to 20 ton metric and for wire ropes with a diameter of up to 38 mm. Thanks to the use of microprocessor technology the PIAB RTM 20D can be calibrated for up to 10 different wire rope dimensions/types. The digital read out display will clearly show the tension of the wire rope selected. No calibration tables are required. When calibrated for a specific rope, an accuracy of 0,5-2% of rated capacity is normally obtained.

The PIAB RTM 20D is a delicate testing instrument for swift, handy and accurate testing of pre tensioned stationary ropes. Thanks to the design of the instrument it can temporarily be overloaded up to 100% of its nominal capacity without affecting the accuracy of the instrument. Thanks to tempered outer rope supports and a centre clamping jaw the instrument gives a long service life with accurate measurements. The RTM 20D is delivered in a robust and light weight transport case (760 x 400 x 170 mm) for easy handling and protection of instrument.
