As a majority of telecom infrastructure is located outdoors, the adverse weather conditions pose a threat in the form of rainwater ingress. This can give way to certain unavoidable consequences like prolonged service interruptions, ultimately leading to costly repair work. In order to address this issue, SST is now using a series of leak detection sensors that have been developed based on the company’s Optomax technology. These sensors are compact, high-performance liquid level switch units equipped with built-in microcontroller functionality, devoid of any moving parts. The devices instead make use of a convenient, reliable, yet expensive infra-red (IR) sensing mechanism.
