Protecting Telecom Equipment with Advanced Liquid Sensor Devices

Since a large proportion of telecom infrastructure is located outdoors, it is always at the risk of exposure to adverse weather conditions. Telecom companies need to protect their infrastructure from the threat of rainwater ingress as the damage it causes can result in dire consequences – leading to extended service interruptions and costly repair work.

Performing systematic inspections can often be a challenging task due to the need for a high number of human resources and the fact that equipment may be installed in remote locations. To overcome this problem, SST Sensing has developed a range of leak detection sensors based on its proprietary Optomax technology.

SST Sensing’s Liquid Level Switch Devices

The compact, high-performance liquid level switch devices offered by SST Sensing feature built-in microcontroller functionality and are free from any moving parts. These devices utilize a more reliable yet simple and inexpensive infrared (IR) sensing mechanism. This convenient, yet effective mechanism works based on the principle that if the sensor tip is exposed to a liquid, the properties of the optical setup will be changed by the liquid, with light that was previously internally reflected being dispersed. As a result, the amount of incident light on the phototransistor of the device is reduced, causing a change in the output voltage. This voltage change can be used to alert telecom operators/carriers about the presence of water in their base stations, fiber optic cabinets, pico cells, etc.

Enclosures have only a limited space as they are packed with electronics and cabling. However, the Optomax devices have a small form factor and can be accommodated in an M10 housing, with a length of just 22.7 mm. Hence, they are suitable to this kind of application setting.

Supporting an operating temperature range of -25 °C to +80 °C, these robust devices are capable of handling severe fluctuations in environmental conditions and maintaining long term operation. An elevated degree of sensitivity can be provided by the IR-based approach, meaning there is no delayed response and risk of damage to valuable apparatus.

The impact of leaks on networking equipment can be heavy, with the consequential downtime being harmful to the telecom company’s reputation and raising frustration for their subscribers. The implementation of our Optomax devices in this scenario is proving increasingly popular. Through only minimal investment, the ongoing functional integrity of vital telecom hardware can be assured.
