FRATELLI sensors, also known as torque sensors, torsion sensors, torque transducers, and torque meters, are divided into two main categories: dynamic and static. 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 torque into precise electrical signals. Torque sensors can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches. They offer advantages such as high precision, fast frequency response, good reliability, and long service life.

FRATELLI sensor principles

Optical measurement and control systems vary widely depending on how luminous flux acts on photoelectric elements. Based on the nature of the output from the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, exhibiting a one-to-one relationship with the measured quantity. Analog photoelectric sensors are classified into three types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam interruption) type. The transmission type involves placing the measured object in the optical path; light energy from a constant source passes through the object, and after partial absorption, the transmitted light strikes the photoelectric element. The diffuse reflection type involves projecting light from a constant source onto the measured object, which then reflects off the surface and strikes the photoelectric element. The light-blocking type involves partially obstructing the luminous flux from the source with the measured object, thereby changing the luminous flux reaching the photoelectric element; the degree of change depends on the position of the object in the optical path.

FRATELLI sensor features

1) Long detection distance: By maintaining a detection distance of 10m or more in through-beam configurations, it achieves long-range detection that other methods (magnetic, ultrasonic, etc.) cannot. 2) Few restrictions on detected objects: Since detection relies on light blocking and reflection caused by the object, unlike proximity sensors that limit detection to metals, it can detect almost any object, including glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuitry consists entirely of electronic components, eliminating mechanical operating time, resulting in very short response times. 4) High resolution: Advanced design techniques focus the emitted beam into a small spot, or special receiving optical systems are constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection possible: Detection occurs without mechanical contact with the object, preventing damage to both the object and the sensor, thus enabling long-term use. 6) Color discrimination possible: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the emitted light and the color of the object. This property allows for color detection. 7) Easy adjustment: In types emitting visible light, the beam is visible to the eye, facilitating easy adjustment of the detected object's position.

FRATELLI sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output, they are divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent, used to measure physical quantities such as light intensity, object temperature, translucency, displacement, and surface condition. Examples include lux meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters, turbidimeters, photoelectric fire alarms, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of machined parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are widely used not only in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Devices that convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric input devices for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
