Product BrochureProduct Datasheet

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 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.

The force transducers of the ZF / ZF-S Series have been designed for the measurement of static and dynamic tensile and pressure forces; they are characterized by their low assembly height at a high measuring accuracy. The force is introduced on one side through a central tapped hole, the other side of the force transducer has to be fixed to a sufficiently rigid plane surface by means of 8 high-strength hexagonal socket-head bolts to be tightened with a defined torque. A strain gauge bridge converts the elastic deformation of the sensing element into an electrical signal that can be evaluated. Compensation and adjustment elements are used to set the required technical data. As a standard, the transducers are equipped with a 3 m connection cable, which has free ends on the other side.

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.
