Great Flexibility with
Multiple Versions
EM400-UDL comes in two versions Standard and Pro versions with different probes optional. With 5 probes at choice, EM400-UDL provides great flexibility to satisfy various demands for professional applications.
Value-added Temperature
and Tilt Monitoring
Device Tilt Status Monitoring
The EM400-UDL is equipped with a built-in 3-axis accelerometer which can be used to monitor the device tilt status and alert the users whether the device is well positioned.
Temperature Monitoring
With built-in NTC thermistor, EM400-UDL can monitor the temperature and send alert in time if the temperature changes sharply which may indicate combustion.
Various Professional
Applications
Whether for industrial settings or in cities, EM400-UDL is dependable to provide accurate and reliable data to optimize operations and improve efficiency.
- Boiler Expansion Monitoring
- Tank Fill Level Monitoring
- Barn Fill Level Monitoring
- Flood Monitoring
- Sewer Water Level Monitoring
Rugged and Reliable IP67
Rated Enclosure
