German Leuze sensors, Leuze models, Leuze prices

Leuze sensors are devices that convert mass signals into measurable electrical signal outputs. When using sensors, the actual working environment of the sensor should be considered first. This is crucial for the correct selection of load cells, as it affects whether the sensor can operate normally, its safety and service life, and even the reliability and safety of the entire weighing system. There are qualitative differences between the old and new national standards in the basic concepts and evaluation methods of the main technical indicators of load cells. The main types include S type, cantilever type, spoke type, plate ring type, membrane box type, bridge type, and column cylinder type.

Leuze sensor introduction

Sensors used in robots to mimic tactile functions. Touch is an important sensory function when humans directly contact the external environment. Developing tactile sensors that meet requirements is one of the key technologies in robot development. With the development of microelectronics technology and the emergence of various organic materials, a variety of development plans for tactile sensors have been proposed, but most are currently at the laboratory stage, with few reaching productization. Tactile sensors can be roughly divided into contact sensors, force-torque sensors, pressure sensors, and slip sensors according to their functions.

Leuze sensor classification

Slip sensors are used to judge and measure the slippage of objects when robots grasp or handle them. It is actually a type of displacement sensor. According to whether there is a sliding direction detection function, it can be divided into three categories: non-directional, unidirectional, and omnidirectional. 1) Non-directional sensors include probe earphone types, which consist of sapphire probes, metal buffers, piezoelectric Rochelle salt crystals, and rubber buffers. When sliding, the probe vibrates, and the Rochelle salt converts it into a corresponding electrical signal. The buffer's role is to reduce noise. 2) Unidirectional sensors include drum photoelectric types, where the slippage of the grasped object causes the drum to rotate, causing the photodiode to receive light signals through the code disk (mounted on the drum's circular surface), and measuring the object's sliding through the drum's rotation angle signal. 3) Omnidirectional sensors use metal balls with surfaces covered in insulating material and forming a latitude-longitude distribution of conductive and non-conductive areas. When the sensor contacts an object and produces sliding, the ball rotates, causing the conductive and non-conductive areas on the ball's surface to alternately contact electrodes, thereby producing on-off signals. By counting and judging the on-off signals, the magnitude and direction of the slippage can be measured. This type of sensor requires high manufacturing craftsmanship.

Leuze sensor applications

Contact sensors are used to judge whether a robot (mainly referring to limbs) has contacted an external object or to measure the characteristics of the contacted object. Contact sensors include types such as micro switches, conductive rubber, carbon-containing sponge, carbon fiber, and pneumatic reset devices. 1) Micro switch: Composed of a spring and a contact. After the contact touches an external object, it leaves the base plate, causing the signal path to disconnect, thereby detecting contact with the external object. The advantage of this normally closed (always connected when not in contact) micro switch is ease of use and simple structure, while the disadvantages are susceptibility to mechanical oscillation and contact oxidation. 2) Conductive rubber type: It uses conductive rubber as the sensitive element. When the contact touches an external object and is pressed, it compresses the conductive rubber, changing its resistance, thereby changing the current flowing through the conductive rubber. The disadvantage of this sensor is that due to differences in the material formulation of conductive rubber, the drift and hysteresis characteristics are inconsistent, while the advantage is flexibility. 3) Carbon-containing sponge type: It has an elastic body made of sponge mounted on a base plate, with carbon-containing sponge arranged in an array within the sponge. After contacting an object under pressure, the resistance of the carbon-containing sponge decreases. Measuring the magnitude of the current flowing through the carbon-containing sponge determines the degree of pressure. This sensor can also be used as a pressure sensor. The advantages are simple structure, good elasticity, and ease of use. The disadvantages are that the uniformity of carbon distribution directly affects measurement results and recovery ability after pressure is poor. 4) Carbon fiber type: Uses carbon fiber as the upper layer, a base plate as the lower layer, and urethane and metal electrodes installed in the middle. When contacting an external object, the carbon fiber is pressed against the electrode to conduct electricity. The advantage is good flexibility, allowing installation on curved surfaces of mechanical arms, but hysteresis is significant. 5) Pneumatic reset type: It has a flexible insulating surface that deforms under pressure, and uses compressed air as the resetting power when contact is lost. When contacting an external object, its internal elastic bubble (beryllium copper foil) contacts the lower contact point to conduct electricity. The advantages are good flexibility and high reliability, but it requires a compressed air source.
