Manhole Cover Open Detector

Product catalog summary

Introduction
Manhole cover sensors are essential for monitoring and protecting underground supply systems such as telecommunication, water, gas, and electricity networks. These systems are vulnerable to unauthorized access and theft, which can lead to accidents and damage to public property.

Conventional Manhole Locks
Traditional manhole locks are used to prevent unauthorized access but pose challenges such as key management and potential road surface unevenness. The advancement in technology has led to the development of automated monitoring systems as part of smart city initiatives.

Manhole Cover Open Detector
The Manhole Cover Open Detector provides real-time monitoring to prevent metal theft and unauthorized access. It uses off-the-shelf sensors and transmits data via LPWAN technologies to a cloud platform, allowing for efficient maintenance planning.

Key Features

Detects open/closed status of manhole covers
Easy installation with wireless communication
Cloud-based GIS dashboard
Automatic alarm and notification support

Benefits

24/7 monitoring with instant alerts
Optimizes maintenance schedules
Flexible deployment in urban and rural areas

Wireless Communication
The sensors support UNB and NB IoT technologies, offering long-range transmission with low power consumption, suitable for urban environments.

Product Guide
The product range includes models WH-SXT-MOC-000G-301, WH-SXT-MOC-000G-302, WH-SXT-MOC-000N-301, and WH-SXT-MWL-000G-301. All models feature a reed switch sensor type, lithium-ion batteries with varying capacities and lifetimes, and are designed to operate in temperatures from -25°C to 65°C with an IP68 rating.

Manhole cover sensors The Best Sensing Solutions—Directly from the street Manhole Protector: From Manhole lock to Manhole cover open detector Manholes leading to underground supply systems are essential for their maintenance, for example, it concerns telecommunication networks, water supply networks, gas supply networks and electricity networks, and so on. Although it is very crucial to a city’s operations, the manhole can be one of the least protected and most vulnerable assets. Nowadays manhole cover failure such as metal theft (for manhole cover or copper cable underneath it) is on the rise...

Manhole cover sensors support two optional wireless communication methods -- UNB (Ultra Narrow Band) IoT technology and NB (Narrow Band) IoT technology. Both technologies have transmission ranges of up to several kilometers in urban environments, with very low power consumption, data are then transmitted to cloud sever for further processing and delivery into the end-users system.
