Page 10: Installation Instructions
Installation Instructions The immersion length of the RTD temperature sensor can considerably influence the accuracy of the device. If the immersion length is too short, measurement errors can occur. When installing the device in a pipe, the immersion length should penetrate halfway into the pipe diameter and ideally also be at least 15 times the diameter of the probe. -

5 System Integration Device and Vendor Identification Device ID 8585472 Vendor ID 1590 Process Data When the PRTX is in Digital Mode, the state of the switch output and the temperature value are transmitted in the form of process data via IO-Link. The signal is initially transmitted in the SIO-Mode (Standard IO-Mode). Digital IO-Link communication starts as soon as the IO-Link master sends the Wake-Up command. -
