German BELENOS sensor BELENOS model BELENOS price

BELENOS sensors, also known as torque sensors, torsion sensors, torque sensors, and torque meters, are divided into two main categories: dynamic and static. Among these, dynamic torque sensors are also referred to as torque sensors, torque-speed sensors, non-contact torque sensors, and rotary torque sensors. Torque sensors detect the twisting moment on various rotating or non-rotating mechanical components. They convert the physical changes in torsional force into precise electrical signals. Torque sensors can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches, offering advantages such as high precision, fast frequency response, good reliability, and long service life.

BELENOS Sensor Introduction

Sensors used in robots to mimic tactile functions. Touch is an important sensory function when humans directly interact with the external environment. Developing tactile sensors that meet requirements is one of the key technologies in robot development. With the advancement of microelectronics and the emergence of various organic materials, numerous development schemes for tactile sensors have been proposed. However, most are currently at the laboratory stage, with few reaching commercialization. Tactile sensors can be broadly classified by function into contact sensors, force-torque sensors, pressure sensors, and slip sensors.

BELENOS Sensor Classification

Slip sensors are used to determine and measure the slippage of objects when a robot grips or transports them. They are essentially displacement sensors. Based on whether they have sliding direction detection capabilities, they can be classified into three types: non-directional, single-directional, and omni-directional. 1) Non-directional sensors include probe-earpiece types, which consist of sapphire probes, metal buffers, piezoelectric Rochelle salt crystals, and rubber buffers. Sliding causes the probe to vibrate, which is converted into corresponding electrical signals by the Rochelle salt. The buffer's role is to reduce noise. 2) Single-directional sensors include drum photoelectric types. Slippage of the gripped object causes the drum to rotate, leading to a photodiode receiving light signals through a code disk (mounted on the drum's circular face). The object's slip is measured via the drum's rotation angle signal. 3) Omni-directional sensors use metal balls coated with insulating material and featuring a latitudinal and longitudinal distribution of conductive and non-conductive areas. When the sensor contacts an object and slips, the ball rotates, causing the conductive and non-conductive areas on its surface to alternately contact electrodes, thereby generating on/off signals. By counting and judging these on/off signals, the magnitude and direction of the slip can be determined. This type of sensor requires a higher level of manufacturing craftsmanship.

BELENOS Sensor Applications

Tactile sensors are used to determine whether a robot (primarily its limbs) is in contact with external objects or to measure the characteristics of the contacted objects. Types of tactile sensors include micro switches, conductive rubber, carbon-impregnated sponge, carbon fiber, and pneumatic reset devices. 1 Micro switch: Composed of a spring and contacts. When the contacts touch an external object, they move away from the base plate, breaking the signal circuit, thereby detecting contact with the external object. The advantage of this normally closed (continuously conductive when not in contact) micro switch is ease of use and simple structure; the disadvantages are susceptibility to mechanical oscillation and contact oxidation. 2 Conductive rubber type: Uses conductive rubber as the sensing element. When the contacts touch an external object and are compressed, the conductive rubber is pressed, changing its resistance and thus altering the current flowing through it. The disadvantage of this sensor is that variations in the material formulation of the conductive rubber lead to inconsistent drift and hysteresis characteristics; the advantage is its flexibility. 3 Carbon-impregnated sponge type: Features an elastic body made of sponge mounted on a base plate, with carbon-impregnated sponge arranged in an array within the sponge. When the contacted object is compressed, the resistance of the carbon-impregnated sponge decreases. Measuring the magnitude of the current flowing through the carbon-impregnated sponge determines the degree of compression. This sensor can also be used as a pressure sensor. Advantages include simple structure, good elasticity, and ease of use. Disadvantages are that the uniformity of carbon distribution directly affects measurement results, and recovery after compression is poor. 4 Carbon fiber type: Uses carbon fiber as the top layer, a base plate as the bottom layer, and urethane and metal electrodes installed in between. When contacting an external object, the carbon fiber is compressed and makes contact with the electrodes to conduct electricity. The advantage is good flexibility, allowing installation on curved surfaces of robotic arms, but hysteresis is significant. 5 Pneumatic reset type: Features a flexible insulating surface that deforms under pressure; upon release of contact, compressed air serves as the resetting force. When in contact with an external object, the internal elastic dome (beryllium copper foil) contacts the lower contacts to conduct electricity. Advantages include good flexibility and high reliability, but a compressed air source is required.
