Industrial Digital Temperature Sensor 4-20 MA Capillary Type, With Farm Temperature Sensor Rs485

Industrial digital temperature sensors are intelligent temperature measurement devices that integrate temperature-sensitive components, signal processing circuits, and digital communication interfaces. They can directly output digital temperature signals and communicate with control systems such as PLCs, DCSs, or single-chip microcomputers without the need for additional analog-to-digital conversion steps.

Compared with traditional analog temperature sensors (such as thermocouples and thermal resistors), digital temperature sensors have the following core advantages: strong anti-interference ability, no need for signal conditioning, direct interface with digital systems, and high system integration.

Features and Descriptions
  • Direct Digital Output: Built-in ADC and signal processing circuit, directly output digital temperature values, no need for external A/D conversion and signal conditioning.
  • Single-wire/Simple Interface: For example, DS18B20 only requires one data line for communication, greatly simplifying hardware design and wiring.
  • Factory Calibration: Chip-level calibration, ensuring accuracy across the full temperature range, no need for on-site calibration.
  • Multi-point Networking Capability: Under the single-wire architecture, multiple sensors can be connected to a single line, facilitating distributed temperature measurement.
  • Low Power Consumption Design: Operating current as low as μA level, extremely low power consumption in sleep mode, suitable for battery-powered devices.
  • High Integration: Fully integrated sensor, amplifier, A/D, digital filtering, and communication interface, occupying minimal PCB space.

Application scenarios: Pipeline/container temperature monitoring, liquid temperature measurement, cold chain logistics, medical thermometers, industrial equipment bearing temperature measurement.
