German HEISE sensor HEISE model HEISE price

HEISE sensor precisely measures the actual displacement of the detected product by detecting the absolute position of the movable magnetic ring through internal non-contact measurement and control technology; the high precision and high reliability of this sensor have been widely applied in thousands of practical cases. Since the movable magnetic ring that determines the position and the sensitive element do not come into direct contact, the sensor can be used in extremely harsh industrial environments and is not easily affected by oil stains, solutions, dust, or other contaminants. In addition, the sensor uses high-tech materials and advanced electronic processing technology, so it can be used in high temperature, high pressure, and high vibration environments. The sensor output signal is an absolute displacement value; even if the power is interrupted and reconnected, data will not be lost, and there is no need to re-zero. Since the sensitive element is non-contact, repeated detection will not cause any wear to the sensor, which can greatly improve detection reliability and service life.

HEISE sensor principle

Optical measurement and control systems are diverse, manufactured based on different principles of luminous flux acting on photoelectric elements. According to the nature of the output quantity of 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 single-valued relationship with the measured quantity. Analog photoelectric sensors can be divided into three major categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The transmission type refers to placing the measured object in the optical path, where the light energy emitted by a constant light source passes through the measured object, and after partial absorption, the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to light emitted by a constant light source being projected onto the measured object, and then reflected from the surface of the measured object onto the photoelectric element. The light-blocking type refers to the measured object blocking part of the luminous flux emitted by the light source, causing a change in the luminous flux projected onto the photoelectric element; the degree of change is related to the position of the measured object in the optical path.

HEISE sensor features

1) Long detection distance: If a detection distance of more than 10m is maintained in through-beam types, it enables long-distance detection that other detection methods (magnetic, ultrasonic, etc.) cannot achieve. 2) Few restrictions on detected objects: Since the detection principle is based on light blocking and reflection caused by the detected object, unlike proximity sensors that limit detection to metals, it can detect almost all objects such as glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuit consists of electronic components, so there is no mechanical operating time, resulting in a very short response time. 4) High resolution: High resolution can be achieved by concentrating the emitted light beam into a small spot through advanced design technology, or by constructing a special light-receiving optical system. It can also perform detection of tiny objects and high-precision position detection. 5) Non-contact detection is possible: Detection can be performed without mechanical contact with the detected object, so neither the detected object nor the sensor will be damaged. Therefore, the sensor can be used for a long time. 6) Color discrimination is possible: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the incident light and the color combination of the detected object. Utilizing this property, the color of the detected object can be detected. 7) Easy adjustment: In types that project visible light, the emitted light beam is visible to the eye, facilitating adjustment of the position of the detected object.

HEISE sensor applications

Photoelectric sensors using photoelectric elements as sensitive elements are numerous and widely used. According to the nature of the output quantity of the photoelectric sensor, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent can be used to measure physical quantities such as light intensity, object temperature, light transmission capability, displacement, and surface condition. For example: illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as sensitive elements. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be made into infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Converting 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 are used as switching photoelectric conversion elements. For example, photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.
