Photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect means that when light is irradiated on certain substances, the electrons of the substance absorb the energy of the photon and the corresponding electric effect occurs.
The photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect, and the phenomenon of photoelectric effect is different.
Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells.
In general, the photoelectric sensor is composed of three parts: transmitter, receiver and detection circuit.
1. The photoelectric sensor is a device that converts light signals into electrical signals, and is a key element for photoelectric conversion in various photoelectric detection systems.
2. The photoelectric sensor is a sensor that uses a photoelectric device as a conversion element. It can be used to detect other non-electrical quantities that can be converted into changes in the amount of light, such as part diameter, surface roughness, strain, displacement, vibration, speed, acceleration, as well as the recognition of the shape and working state of the object. It can also be used to detect non-electricity that directly causes changes in the amount of light, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; photoelectric sensors have the characteristics of non-contact, fast response, and reliable performance.
Capsule counting machine is a packaging device for automatic counting. It can count pills of different shapes and specifications. It has the advantages of small drug wear, simple structure, beautiful appearance, convenient maintenance, and easy cleaning of the equipment.
Shengde automatic capsule counting machine uses the principle of photoelectric induction to count, divide and transport the sensed medical particles, and all operating data can be monitored and set in real time. The capsules are automatically transferred into the lower hopper through the vibration effect of the vibrating plate and counted one by one. A reversing electromagnet is installed at the discharge port to ensure that the equipment does not stop when changing bottles. When the set quantity is filled, the electromagnet automatically reverses to fill the bottle on the other side. The body is made of high-quality stainless steel, with exquisite dimensions, simple structure, beautiful appearance and easy maintenance.
SED-S series automatic pill counting machine is mainly suitable for medicine, industry, chemical industry, food and other industries. It can be widely used for counting and bottling solid preparations, such as pills, sugar-coated tablets, plain tablets, soft and hard capsules and other shapes of medicine granules.
