Contact temperature sensors

Temperature sensors

Available in:

3 Series

Our contact temperature sensors are designed to detect process temperatures continuously and/or provide a switching response. This versatility makes them ideal for a wide range of applications, including machine tools, mobile work machinery, pumps, compressors, as well as hydraulics and pneumatics.

These sensors are available in different models, with and without displays, to meet the diverse requirements of various applications. Their rugged IP67 housing also makes them perfectly suited for harsh industrial environments.

Each of our contact temperature sensors includes a protective tube with a fixed process connection, allowing for direct threading into the process.

The special features of our temperature sensors

  • Version with rotatable, highly readable display: Flexible installation and operating convenience
  • Versions without display: Compact form factor and high resistance to vibration
  • Interfaces: Analog signals and switching points
  • Rugged M12 connector for ease of integration
  • UL and CE approval
