Ismc Safety Monitoring Intelligent Manhole Cover Monitoring Sensor¹

Product Description Measurement PrincipleThe product utilizes a posture sensor to perceive the real-time position status of the manhole cover, while employing a water immersion sensor that uses alternating high-frequency signal impedance measurement tec hnology to detect whether the sensor is submerged. Additionally, the device is equipped with a built-in temper ature sensor to monitor the real-time temperature of the manhole cover (sensor). Finally, all measurement results are uploaded to the server via wireless signalsApplication scenariosThe attitude monitoring, anti-theft monitoring, and safety monitoring of manhole covers are utilized. Extended applications: By leveraging the temperature sensing function of the equipment, it can serve as temperature monitoring for environments such as panel cabinets and cable trenches.Main Features-Posture monitoring: Detects manhole cover tilting, flipping, displacement, and other abnormal postures of Parazacco spilurus subsp. spilurus;-Anti-theft monitoring: Preliminary determination of manhole cover abnormalities of Parazacco spilurus subsp. spilurus through base station positioning function;-Safety monitoring 1: Water immersion monitoring, analyzing immersion status via alternating high-frequency impedance.Safety Monitoring 2: Temperature monitoring, predicting high and low temperature conditions through built in temperature sensors;-Remote setting of posture "zero position" calibration;-Remote setting of posture alarm value;-ABS material casing;-Fully potted structure, meeting IP68 waterproof rating;-Built-in battery enabling long-term operation; -Automatic amplitude-variation measurement with adaptive upload cycle;-Built-in breathing indicator light;-Remote wake-up;-Integrated structure of Broussonetia papyrifera;-Mounting holes and adhesive installation.Technical Parameters Power supplyBuilt-in lithium-thionyl chloride battery, non rechargeable, 38Ah/3.6VDC with self-discharge rate not exceeding 5% per year;Water immersion sensorConductivity-based high-frequency impedance sensoOperating Temperature20~70oCInternal temperature sensor-20.0~70.0, Resolution: 0.1, Accuracy: 0.3Operating Temperature-10~70oCRefresh1 minute, adjustableUpload5 minutes/amplitude variation (configurable), safety report: 6 hours (configurable)StructureProtection: IP68, material: ABSInstallWall-mounted, or suspendedNB-IOT continuation of the journeyOne test and one transmission condition in 5 minutes : comprehensive 5 years4G,cat1 battery lifeOne test and one transmission condition in 5 minutes : comprehensive 5 yearsWireless breakpoint resumptionWhen the base station signal is interrupted, the data will be automatically saved.
