- The probe should be entirely in the measurement environment, with sufficient distance to the outer walls of the chamber or duct. Air should flow freely around the probe.
- The probe location should represent well the environmental or process conditions, and it should be as clean as possible.
When using the 3-wire output module, you may also connect a fourth wire to the Out - terminal. It is internally connected to the Vin - terminal. This will help reduce electrical interference, especially when using the 0 ... 1 V output.
1 Installation using mounting flange is recommended for the 400-mm-long probe option only.
With the shorter, standard-length probe, this installation method increases the risk of heat conduction.
2 Use 2 mounting clamps for stability
when installing the 400-mm-long probe.
