The Best Fit for Temperature Measurement

  • X-13S-K

The X-13S™ thermocouple expansion module is used with an X-400™ or X-600M™ controller. It is a 2-channel signal conditioner for Type-K thermocouples. One or more X-13S expansion modules can be connected with a ribbon cable that provides both power and communication.

  • 2 Channel Type-K Thermocouples
  • Expansion Module for the X-400 and X-600M

Thermocouples come in many shapes and sizes and apply to countless applications, including extreme temperature measurement. When connected to an X-400 or X-600M, the X-13S provides a flexible and reliable way to monitor temperature over a network. It’s suitable for use with freezers, ovens, fermenters, generators—anywhere precise, rugged temperature sensors are required.
