SENTINEL – Temperature Sensors & Transmitters

SENTINEL temperature sensors and transmitters are temperature detection devices that convert physical temperature into electrical or other types of output signals to meet the monitoring needs of industrial automation systems.

Features
  • Robust stainless steel construction: Constructed with 304/316L stainless steel housings for corrosion resistance and high-pressure tolerance, suitable for extreme high and low-temperature industrial environments.
  • Flexible and customizable design: Supports various installation configurations and customization to meet specific application requirements.
  • Versatile output options: Provides switch outputs, analog signals, and IO-Link digital communication, enabling real-time data acquisition, remote configuration, and self-diagnostics.
  • Key industry applications: Commonly used in vacuum coating systems, metallurgical cooling loops, and CNC machine tool environments. Accurate temperature control enhances both production efficiency and product quality stability.
  • Working Principle

    The working principle of the temperature sensor is primarily based on These sensors primarily use the linear temperature-resistance characteristics of platinum resistance elements (e.g., Pt1000), which has a resistance of 1000 ohms at 0°C and exhibits highly linear resistance changes with temperature. Measurement circuits detect the change in resistance and convert it into a standardized electrical or digital signal.
