The APC NetBotz Spot Fluid Sensor (type NBES0301) is a universal leakage point sensor for early detection of liquids at individual locations in data centres, network rooms or server rooms. It serves as a supplement to NetBotz monitoring systems and enables monitoring of liquid accumulations at a defined point, which can be up to 4.572 m (15 ft) away from a NetBotz device or sensor pod. The sensor operates with electronic circuits that detect the presence of liquid via electrical conductivity. Detection occurs through sensor contacts, which close an electrical circuit upon contact with liquid, thereby triggering an alarm.

Applications

The sensor is specifically designed for use in IT infrastructures, where early detection of water or other liquids is critical to prevent damage to equipment and systems. It is suitable, for example, for monitoring floor areas under server racks, near air conditioning units, at pipe lines, or in areas where liquid leakage or overflow is possible. The maximum distance of 4.572 m allows for flexible placement without requiring the main device to be located directly at the sensor site.

Functions and Equipment in Detail

The sensor features an RJ-45 coupling, enabling wired transmission of sensor data. The transmission technology is therefore wired, ensuring stable and reliable signal transmission. The sensor contacts are designed to create an electrical short circuit when in contact with liquid, which is detected by the sensor and transmitted as an alarm message. To avoid false alarms, it is important not to place the sensor on conductive surfaces such as metal or wet cement, as this may cause unintended short circuits. To prevent such short circuits, the use of the included insulating film, on which the sensor should be placed, is recommended.

Technology Explained Simply

The operation is based on the electrical conductivity of liquids. When liquid touches the sensor contacts, an electrical path is created, which is detected by the sensor. This state is interpreted as a leakage and triggered. The sensor unit is liquid-resistant, meaning it can withstand brief contact with liquid, but is not designed for prolonged immersion. The RJ-45 socket is also liquid-resistant, although water should not collect at this point to avoid corrosion. Cleaning should be done exclusively with tap water; soaps, cleaning agents or other chemicals are not permitted.

Compatibility and Accessories

The sensor is compatible with all NetBotz devices from the 250A and 700 series. It can be used as a supplement to other sensors such as the Leak Rope sensor to ensure comprehensive coverage along the sensor length. The use of cable ties, provided as accessories, enables secure and orderly attachment of the sensor at the desired location.

Installation and Mounting

Installation involves securing the sensor at the desired location, using the insulating film to avoid short circuits. Connection is made via the included cable with RJ-45 plug to a NetBotz device or sensor pod. The maximum cable length is 4.572 m, allowing for flexible placement. Installation requires no special tools, although positioning should be done to ensure optimal coverage of the area to be monitored.

Operational Advantages

The sensor provides reliable and early detection of liquids, reducing response time in case of potential damage. The wired transmission ensures stable signal transmission without sensitivity to electromagnetic interference. The liquid-resistant construction increases the lifespan and reliability of the sensor in humid environments. Compatibility with various NetBotz systems enables flexible integration into existing monitoring infrastructures.

Operating Conditions

The sensor can be operated at temperatures from 0 to 45 °C and relative humidity from 0 to 95 %. Storage is possible at altitudes up to 15,000 m and relative humidity from 0 to 95 %. The operating altitude thus makes it suitable for use in high mountain regions or airport IT infrastructures. Dimensions are 64 x 25 x 64 mm, weight is 270 g. Compliance with the EU RoHS Directive (Restriction of Hazardous Substances) is ensured, with compatibility confirmed for exemptions 6(c) and 7(c)-I.
