Transmitters with remote transmission devices are suitable for the following situations

1. It is necessary to isolate the high-temperature medium from the transmitter.

2. The tested medium has a corrosive effect on the sensitive components of the transmitter

3. Suspended liquid or high viscosity medium

4. The tested medium solidifies or crystallizes due to changes in environment or process temperature

5. When replacing the measured medium, it is necessary to strictly purify the measuring head. The measuring head must be kept clean
