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.

[post_content] => The Magtrol SGS-350 is a strain gauge bridge simulator made entirely with passive components and an aluminum housing designed for use in extremely harsh environments.
The SGS-350 can be used in place of a strain gauge sensor with 0 ... 2 mV/V sensitivity, in order to test or calibrate an LMU 210 Series Load Monitoring Unit (or other model), including threshold overload testing.
The SGS-350 can be supplied with 5 ... 10 V DC power supply.

[post_content] => The SK-02 Cable Sensor is a low cost load cell specially designed to measure the tension force on hoisting rope. Easy installation does not require the hoist to be dismantled nor modified. The SK-02 sensor family covers a large range of cable diameters from 8 to 36 mm and loads 8 k·N (~800 kg) to 150 k·N (~15 tons). Together with a load conditioner (LMU Series) and a digital display (AN Series, GAD Series), The Magtrol SK-02 Cable Sensor constitutes a complete measuring system for continuously monitoring loads and detecting overloads.

[post_content] => Magtrol's ZM Series Force Transducers are designed to measure static and dynamic pressure forces. They are characterised 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.
