Environment
Ambient temperature
−20...+60 °C (sensor, transmitter)
Note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in
warm climatic regions.
• If both fluid and ambient temperatures are high, install the transmitter at a
remote location from the sensor (
→ “Fluid temperature range”).
