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.

Magtrol's ZM Series Force Transducers are designed to measure static and dynamic pressure forces. They are characterized by their small dimensions.
Manufactured in stainless steel or high-resistance aluminum, these transducers can be used in a wide variety of applications. In particular, the stainless steel versions with a high degree of protection can be used everywhere without restriction, even in harsh environments.
The sensor element consists of a diaphragm body equipped with metal foil strain gauges, which forms a hermetically sealed chamber filled with dry nitrogen. In standard mounting, the transducers are fixed with screws on a flat surface. The force is introduced vertically (without transverse force) via the universal ball joint, either directly or via a metal adapter interface.
All Magtrol ZM Series transducers are supplied with a 1.5 m long connection cable with loose ends.
Optionally, they can be supplied with a built-in amplifier (ZM‑E). Then, an Output Signals of 0 ... 10 V DC or 4 ... 20 mA can be selected.

[post_content] => MAGTROL offers a wide range of Load-Force-Weight Transducers with optional integrated electronics or Load Monitoring Units (LMU) with B.I.T.E. functions creating an ideal measurement system which continuously checks for overloads and short circuits. Idealy for use on Safety Applications according to ECE-R10, ISO 13849-1 : CAT4 & PLe (LE 600 Series); ISO 13849-1 : CAT2 & PLd (LE 400 Series).
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 LE Series Load Measuring Pins are rugged with high resistance stainless steel and tight construction. Available in several standard ranges from 2.5 kN to 1 250 kN, their operation remains trouble-free and reliable even in electromagnetically difficult environmental conditions.
Design
Magtrol's Load Measuring Pins have two 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. The positioning and orientation of the strain gauges have been optimized by means of the finite element method (FEM).
