Environmental protection meter
Passive IoT environmental protection metering is a self-receiving working power supply (no need to use switching power supply), wireless transmission real-time power detection unit, detection range: current: 0-1000A; voltage 0-1000V. Monitorable: voltage, Current, frequency, active power, reactive power, power factor, harmonic analysis and accumulated power.
It's with Internet of Things NB-IOT, LORA, 433MHz and other wireless transmission, RS485, CAN and other wired transmission.
This product is mainly used for environmental protection condition monitoring, from environmental protection equipment monitoring to enterprise production status monitoring, collecting pollution equipment emission data and pollution control equipment data, controlling the rational use of enterprise equipment, is an important means to consolidate the existing pollution source automatic monitoring construction results. . And by collecting the total electricity consumption of the enterprise and the electricity consumption data of the production equipment and environmental protection equipment, the data analysis shows that the production conditions are abnormal.
1 It is especially suitable for power detection in passive and non-wired communication environments, with zero wiring and easy installation;
2 Wide detection range: current: 0-1000A; voltage 0-1000V;
3 Communication method: It has various wireless transmission modes such as Internet of Things NB-IOT, LORA, etc., and has self-organizing network function;
4 Strong detection function: can detect voltage, current, frequency, active power, reactive power, power factor, harmonic analysis and accumulated power;
5 High reliability:
The product can work in a high pressure environment of 10KV.
It has the function of detecting data storage, and data self-protection of power-down and automatic transmission after reply.
The anti-interference ability reaches the national standard level or above.
