An electronic or electrochemical sensor that converts and transmits data digitally is known as a digital mark sensor. Analytical measurements, such as those of liquids’ chemical and physical properties, frequently involve the use of sensors. pH value, conductivity, oxygen, redox potentials, and other parameters are frequently measured. In the industrialized world, these measurements are utilized and provide crucial information for process control.
In the past, analogue sensors were utilized, but digital sensors are increasingly prevalent today.
Digital mark sensing is A method for data input in which electrically conductive marks, usually made with a soft graphite pencil on a preformatted card or form, are electrically sensed. This method has been displaced by the more reliable method of OMR (i.e. optical mark reading) in which the marks are detected photoelectrically.
The sensor and the cable often are not connected permanently, but through electrical connectors. This classical design with connectors and transmission of small currents through a cable has certain drawbacks too.
The Global Digital Mark Sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
DIGITAL MARK SENSOR LX-100 – The LX-100 Series is a combination LED contrast and color sensor that can be used as both a high-precision color sensor and a high-speed contrast sensor, for example, to quickly and reliably detect printer marks.
During teach-in (static or dynamic teach-in method), the Sensor automatically selects the best emitting LED from the transmitting light source (red, green, and blue LEDs) in contrast sensing mode.
This Sensor is ideal for printing presses and other high-speed processing applications due to its 45-s response time. An integrated microprocessor with a 12-bit A/D converter digitally processes the red, green, and blue primary color component signals in color mode.
This makes it possible to accurately distinguish even the tiniest tints and color variations.It consists of Three Different Emitting LEDs (Red, Green, Blue) along with a high Precision Coaxial Reflective Optical System.
It also has a High Resolution 12-Bit A/D Converter with 4-Digit Digital Display along with different modes Timer Function (ON/OFF-Delay) giving out Two Inverse Outputs (Cable Type)
