Paperless recorderIt is an intelligent data recording device based on microprocessors and electronic storage technology, which uses high-performance ARM chips to real-time collect, process, and store analog signals (such as temperature, pressure, flow rate, etc.) from industrial sites, replacing traditional paper recorders with pen, ink, and paper. The workflow is divided into four steps:

Data collection: Sensors convert physical signals (such as temperature signals from thermocouples) into digital signals;

Data processing: The microprocessor performs filtering, calibration, and compensation operations on the signal (such as temperature and pressure compensation);

Data storage: Data is stored in binary form in built-in flash memory or SD card, and supports cyclic overwrite;

Data display: Real time display of numbers, curves, bar charts or alarm lists through LCD screen, and support touch operation.

　　Paperless recorderTypical application scenarios:

Chemical reactor monitoring

Real time recording of temperature and pressure curves, automatic interlocking shutdown when exceeding limits, to avoid explosion accidents.

After being applied in a certain petrochemical enterprise, the equipment failure rate decreased by 65%, and the annual unplanned downtime loss was reduced by more than 2 million yuan.

Pharmaceutical sterilization process validation

By calculating the F0 value (equivalent value of wet heat sterilization time temperature), ensure compliance with GMP standards.

A certain vaccine production enterprise has adopted paperless recorders instead of manual recording, and the data validity certification pass rate has been increased to 100%.

Smart water management network monitoring

Integrated pressure, flow, and pH sensors, wirelessly transmitted to the cloud platform via LoRa.

After the deployment of a water management group in a certain city, the leakage rate of the pipeline network decreased from 18% to 9%, saving over 5 million tons of water annually.

Laboratory research data collection

Support multi-channel synchronous sampling (such as 16 temperature channels and 8 voltage channels), with a sampling frequency of up to 1kHz.

After application in a laboratory at Tsinghua University, the data collection efficiency has been improved by 10 times, with a repeatability error of ≤ 0.1%.
