Description

The EM400-UDL-N03GL-C100 from Milesight is a multifunctional NB-IoT ultrasonic distance sensor, suitable for measuring both liquid and solid materials.

By using ultrasonic distance detection, the EM400-UDL delivers stable and reliable performance when detecting various solid or liquid substances. Thanks to the contactless distance measurement, the probe of the EM400-UDL remains unaffected or contaminated by the detected medium and delivers highly accurate measurements.

The sensor also supports a built-in 3-axis accelerometer to detect the status of the waste bin lid and a built-in NTC thermistor to detect waste combustion.

The IP67-rated housing ensures that the sensor is protected against dust, water and other environmental hazards, making it resistant to harsh environments. The PCBA is also coated, providing an extra layer of protection against moisture, dust and other contaminants that can damage electronic components.

By default, the EM400-UDL comes with batteries, mounting kit and a 2-year warranty.

Application & use

When to use

At locations without a LoRaWAN network where cellular coverage is available
When you want to measure levels in deeper tanks or silos up to 1000 cm
In harsh or contaminating environments where the sensor must be protected

Ideal for

Waste container and level monitoring
Tank and silo monitoring with greater depth
Distributed measuring points with NB-IoT or CAT-M1 coverage
Smart city applications

Not suitable for

Locations without NB-IoT or CAT-M1 coverage
Applications where a shorter measuring range is sufficient
