Photoelectric sensors

Senyd Photoelectric sensors are devices that use light to detect the presence or absence of an object. They work by emitting a light beam (usually infrared, visible, or ultraviolet light) towards the object to be detected. When the object interrupts the light beam, the sensor detects the change in light intensity and triggers a response, such as activating a switch, counting objects, or measuring distance.

There are several types of photoelectric sensors, including through-beam sensors, retro-reflective sensors, and diffuse reflective sensors. Through-beam sensors consist of a separate transmitter and receiver placed opposite each other, with the object passing between them to break the beam. Retro-reflective sensors have a built-in reflector that bounces the light back to the sensor, while diffuse reflective sensors detect the light reflected directly from the object.

Photoelectric sensors are commonly used in industrial automation, packaging, material handling, and robotics applications due to their reliability, versatility, and ability to detect a wide range of objects regardless of color, shape, or material. They are also preferred in applications where contact-based sensors are not suitable due to environmental conditions, such as dust, dirt, or moisture.

Submersible pressure Level transmitter datasheet

As a reliable supplier, Senyd sensor provides a wide range of level transmitters and transducers for process control, marine, and industrial gases, food and beverage, HVAC and telemetry, etc. Our product family includes level probes, level transmitters, submersible level sensors, and contactless level sensors like ultrasonic level sensors and radar level sensors.

Senyd submersible level transmitters and transducer have stainless steel construction, flange installation, local display, and calibration. It has an ATEX explosion-proof version optional for hazardous environment applications. The submersible level transmitters are widely used for the liquid measurement and control of petroleum, chemical industry, power station, city water supply, drainage, hydrostatic water, and hydrology.

Intelligent level transmitters, level sensors, and level transducers output digital RS485, hart, and Modbus output signals. Our digital level transmitters are suitable to measure the tank level such as water tank, oil tank, storage tank, etc. The intelligent digital level sensors are IP68 protected and anti-corrosive, featuring high accuracy. Hence, they can be used as fluid or liquid level sensors to detect industrial water, sea water, underground water, etc.
