HRL Series – Anchor Load Cell

Product Description

HRL Series load cells consist of a high quality stainless steel. This compact load cell is designed specifically for heavy duty use on construction sites and include load cells with a range of 600 … 3 000 kN. Special designs are available upon request. The attached shielded cable includes a water-proof connector with cap. Versions without the connector are available as an option. Cable lengths are customizable according to the installation requirements; for further information please contact us. The data collected from the strain gauge is proportional to the applied force. The signal is transmitted to the monitoring unit for amplification.

LB 200 Series Load Measuring Pins can be used alone or as part of a complete measurement system. Magtrol offers a wide range of Load-Force-Weight Transducers in various executions and accuracy classes and our Load Monitoring Units (LMUs) constitute an ideal safe measurement system which continuously checks for overloads and short circuits.

MAGTROL Load Measuring Pins are used to measure load and force and provide overload protection. The pins are mounted into machines in place of normal shafts and fitted with strain gauges, allowing them to produce a signal proportional to the measured load. Manufactured in Switzerland, Magtrol’s LB 200 Series Load Pins are rugged with high resistance stainless steel and tight construction, designed specifically for use in harsh industrial environments. Available in several standard ranges from 2.5 kN to 1250 kN, these highly ergonomic pins can be used for either new or refitted installations and are adaptable to various conditions.

Design

The Magtrol Load Pin has 2 circular grooves and an axial bore. Inside the central bore, adjacent to the external grooves, the strain gauges are mounted in a full-bridge configuration (double full-bridge for LB 230 models). The positioning and orientation of the strain gauges have been optimized by means of the finite element method (FEM). Any transverse or axial forces, even when acting on any part of the pin, have practically no influence on the measurement signal.

It is used by many high end watch manufacturers for measuring the friction in the movement of mechanical watches and is also used in various medical applications. The MBB-02 is entirely made of aluminum to combine lightness and stability of measurement. It has a nominal capacity range of 0.01 N to 5 N and uses semi-conductor strain gauges. Having a larger gauge factor than foil types, semiconductor strain gauges allow the measurement of very small strain. The sensor integrates a built-in overload protection offering up to 25 times security. Dedicated to laboratory applications, it is suitable for a temperature range of +15 °C to +25 °C. It can be easily connected to a PC or display unit through an external Wheatstone bridge amplifier. A version for Air Humidity compensation in ranges of 30 % to 60 % HR is also available. Applied force radially acts on  the sensors pin which can be independently positioned in 2 different locations, thus offering more operating flexibility. Special versions with various cable lengths and connector outputs are also available.
