Multi channel data processor

The OM1100 series multi-channel data processor is designed using new digital analog technology

★ Supports various full bridge inductive sensors, currently including 5 types: OME, Solartron, Marpos, Mahr, and user-defined

Sensor, selectable by button or serial command

★ Supports 5 transmission rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, selectable with buttons

Or serial command selection

★ Digital supports 1-8 channels, analog supports 1-4 channels; Adjustable analog output voltage multiplier, automatic calibration at 0 points

★ Free selection of positioning size with minimum resolution, also capable of zero setting operation

★ With excellent stability and a large measurement range, it fundamentally solves the problems of communication instability, data mutation, and large temperature drift

★ All wiring adopts shockproof and anti drop design, providing two installation methods: embedded installation and workbench installation

★ Provide customized design and production, customizable communication protocols according to requirements, with extremely high cost-effectiveness

The main problems currently existing in the industry and corresponding indicators or solutions for OM1100:

Existing issues Solution measures or indicators remarks
The fluctuation of the factory power supply caused the instrument to malfunction, and the temporary drop of the factory power supply caused the equipment values to temporarily jump and become inaccurate Adopting DC24V switch power supply and adding filtering measures to solve interference. The minimum input can be as low as 16V, and it will fail in other devices such as PLC and display screen. ——
Long term work and machine shaking can easily cause loose power cords All interfaces are fixed with screws and designed to prevent detachment. ——
Adapting to a single sensor can easily make it difficult to purchase a certain model of sensor, and when there are technical or business issues, it cannot be replaced Provide 4 commonly used sensors and a sensor that users can freely choose from Switch between four types of sensors using buttons or serial commands. Users can freely select sensor settings and refer to the manual of the macro measuring instrument
The communication of the digital measuring instrument is unstable, causing the PLC to hang up due to the serial port, or the PLC needs to restart the serial port after discovering that the serial port is unstable Using imported serial port chips and adding interface circuit processing to ensure normal serial communication. ——
The serial communication rate of the digital measuring instrument is single, and in special circumstances, it cannot meet the communication requirements Provide 5 speed options to choose from, suitable for low-speed communication requirements when converting RS485 to serial port, as well as high-speed communication requirements for laboratory desktop PCs. Button or command operation
Abnormal fluctuations in measurement results, such as a sudden jump from 22.5 to 122.5 Optimize circuit board design and software algorithms to ensure normal results and timely response. ——
The temperature drift is large, and there are significant differences in the morning, middle, and evening time periods Adopting new technologies and solutions to solve the problem of large temperature drift, with temperature drift<5 resolutions within the range of 0-55 ℃ If the resolution is 0.1um, then<0.5um
The display screen is prone to malfunctions, with the brightness becoming darker over time, resulting in light leakage, and the periphery emitting light but the middle of the screen being dark Adopting a true color LCD screen, with automatic sleep function for LCD after timeout Only applicable to instruments with display
The variable resistance knob of the analog measuring instrument is prone to breakage, and the vibration during operation can easily cause poor contact at the contact points of the variable resistance, resulting in abnormal jumping of the measurement results Use buttons instead of knobs to adjust with resolution as the minimum scale,
Can accurately locate and solve abnormal jumping at the same time.
——
The analog measuring instrument has a single voltage multiplier output and cannot meet the requirements of multiple accuracies and measurement ranges. For example, the ultra miniature fitting instrument requires very high accuracy, while the hole measuring machine requires relatively lower accuracy Users can define the voltage multiplier themselves, with a minimum resolution range of (100-2666). The higher the voltage multiplier, the higher the accuracy, and the smaller the output range. Just press the button or use the serial port command to operate
