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] => The MBB-02 Miniature Force Sensor is designed for micro-measurement. 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.
