Milesight

Spot leak detection sensor

Milesight EM300-SLD-868M is a point LoRaWAN leak sensor designed for rapid detection of water and other conductive liquids. The external probe connected by a cable with a length of 1,5 m responds when the liquid reaches a level of approximately 5 mm.

The device also measures temperature from −30 to +70°C and humidity from 0–100% RH. The IP67 enclosure, storage for 2800 records, data retransmission, Milesight D2D, and a replaceable 4000 mAh battery enable long-term monitoring of server rooms, technical rooms, water installations, basements, and other areas at risk of flooding.

EM300-SLD — Rapid Leak Detection at a Specific Point

Milesight EM300-SLD is a wireless sensor designed to detect the presence of water and other conductive liquids in locations particularly at risk of flooding.

The external probe with two electrodes can be placed directly next to a pipe, pump, air conditioner, technical device, or on the floor. When it comes into contact with a sufficient amount of liquid, the device generates an event and transmits the information via the LoRaWAN network.

Point Protection for Locations Most at Risk of Leaks

Point Detection

The compact probe can be positioned exactly where a leak is most likely to occur.

3 Functions in 1

In addition to leak detection, the device also monitors ambient temperature and humidity.

Alarm via LoRaWAN

Information about detected liquid can be automatically transmitted to the supervisory system and used for immediate alarming.

Where Can the EM300-SLD Be Used?

Server Rooms and Data Centres
Pipelines and Valves
Pumps and Pumping Stations
Technical Rooms
Air Conditioning and HVAC
Basements and Garages

Place the Probe Exactly Where Water May Appear

The EM300-SLD is designed to protect specific critical points. The probe can be placed directly beneath a pipeline connection, valve, pump, or device whose failure could cause a leak.

This solution is particularly practical where the source of a potential leak is well known and there is no need to use a detection cable over a larger area.

Local Response Without a Gateway

The EM300-SLD supports Milesight D2D, allowing leak information to be transmitted directly to a compatible Milesight device without waiting for communication with the server.

This makes it possible to use the event to locally activate an alarm, relay, valve, or another automation component.

2800 Records and Retransmission

2800 Records

The device can locally store up to 2800 historical records.

Retransmission

Data stored during temporary communication loss can be retransmitted after the connection to the LoRaWAN network is restored.

Data Recovery

The Data Retrievability function enables historical data stored directly in the device to be retrieved.

IP67 Enclosure and UV Resistance

IP67

The enclosure protects the electronics against dust and water, increasing reliability in technical rooms and outdoor applications.

UV Resistance

The design is also suitable for operation in locations exposed to solar radiation.

Flexible Mounting

The transmitter can be mounted using screws, 3M tape, or cable ties, while the probe can be mounted using screws or 3M tape.
