Industrial Data Logger - Component for Sensor Data Recording

Product Specifications

Technical details and manufacturing context for Data Logger

Definition

A data logger is a dedicated electronic component within an industrial system that autonomously collects, timestamps, and stores measurement data from various sensors and instruments. Its role is to provide a reliable, chronological record of system parameters (such as temperature, pressure, flow, voltage, or digital states) for process monitoring, quality assurance, troubleshooting, and regulatory compliance. The device is typically housed in a rugged enclosure and connects to sensors via wired terminals or wireless receivers. Internally, an analog-to-digital converter (ADC) transforms continuous sensor signals into discrete digital values. A real-time clock timestamps each reading, and a microprocessor manages the sampling rate, applies scaling or filtering, and formats the data. The processed data is written to non-volatile onboard memory, such as flash storage or an SD card. Data loggers operate on low power, often with battery backup, to ensure continuous recording even during main power interruptions. They are used across industries for long-term monitoring and data acquisition. Typical specifications include 4–16 input channels, sampling rates from 1 to 1000 Hz, input voltage range of 0–10 V, measurement accuracy of ±0.1% FS, operating and storage temperatures of -40 to 85 °C, humidity range of 0–95% RH (non-condensing), ingress protection ratings of IP54–IP65 per IEC 60529, power supply of 9–36 V DC, power consumption ≤5 W, data storage capacity of 1–32 GB, communication interfaces such as RS-232, RS-485, and Ethernet, dimensions of 100–200 mm (width × height × depth), and weight of 0.5–2.0 kg. These values are reference ranges and must be verified for the specific model and application. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The data logger physically functions by connecting to sensor inputs via wired terminals or wireless receivers. Internally, an analog-to-digital converter (ADC) transforms continuous sensor signals into discrete digital values. A real-time clock timestamps each reading. A microprocessor manages the sampling rate, applies any necessary scaling or filtering, and formats the data. The processed data is then written to non-volatile onboard memory (e.g., flash storage or an SD card). It operates on low power, often with battery backup, to ensure continuous recording even during main power interruptions.
