Application
iTHERM CompactLine TM311 is developed for universal use in hygienic and aseptic applications in the food & beverages and pharmaceutical industries, and for optimum standardization for machine and skid builders.
Function
The compact thermometer measures the process temperature with a Pt100 sensor element (class A, 4-wire). An optional built-in transmitter converts the Pt100 input signal. The device with integrated electronics automatically detects the type of communication (IO-Link or 4 to 20 mA).
Application example
The immersion length of the compact thermometer can considerably influence the accuracy. If the immersion length is too short, measurement errors can occur as a result of heat conduction via the process connection and the vessel wall.
If installing in a pipe, the immersion length should ideally correspond to half of the pipe diameter.Installation possibilities: pipes, tanks or other plant components.

IO-Link
Besides its general benefits, summarized below, using IO-Link point-to-point communication with our temperature sensor TM311 allows:
- Commissioning via software
- Storage of the configuration
- Use as simple temperature switch (1 Output)
General benefits of IO-Link
Digital measured values:
- Faultless transmission (e.g. EMC caused)
- No conversion, thus a higher total accuracy
More data
- Possibility to carry more values
- Detailed fault information
- Additional process information
Central parameters storage
- Possibility to load set up parameters from the master into a device
- Configuration can be duplicated from one device to the next
- Remote sensor maintenance
