Page 2: Measuring Principle
The universal power supply works with an input supply voltage of 20 to 250 V DC/AC, 50/ 60 Hz, which means that it can be used in all international power grids. More information on this can be found in the Technical Information (see "Documentation"). Endress+Hauser... -
Page 3: Equipment Architecture
Anti-kink spring, 50 mm (1.97 in) The resistance thermometers of the Omnigrad T TST310 series are designed as cable sensors. The actual RTD sensor element is fitted in the sensor tip and mechanically protected. In principle there are bendable and non- bendable versions of the cable sensor;... -

Page 8: Installation Conditions
B: For pipes with a small cross-section, the sensor tip must reach to the piping axis or a little farther (=NL). C: Tilted orientation. The insertion length of the thermometer can influence the accuracy. If the insertion length is insufficient, heat dissipation via the process connection and the container wall can cause measurement errors. For installation Endress+Hauser... -
