Micro water density online monitoring device (JC-OM500-01)

● Function Introduction

JC-OM500-01 typeMicro water density online monitoring device（The system host is used for on-site data collection and recording. Using color LCD display, with clear handwriting, displaying the SF of phase A, B, and C of a certain switch on site₆The moisture content, temperature, pressure, density, and other information of the gas are clear at a glance. The preset threshold output alarm and lockout signals can be used, and data communication with the background can be achieved through RS485 (or TCP/IP).

main features

(1) High precision and high reliability
The transmitter adopts imported high stability sensors, which have been corrected and compensated by the internal circuit of the transmitter, resulting in good output linearity and high accuracy; The external structure of the transmitter is also more suitable for measurement in high-frequency electric field environments. It is integrated with the circuit processing part to reduce interference coupling and improve the stability and reliability of the circuit's long-term operation.

(2) Realize online monitoring and status maintenance
This monitor can operate for a long time with a hanging line. Its equipped RS-485/CAN communication interface can upload monitoring data in real time to the monitoring center. When the measured gas index exceeds the standard, the monitor will automatically upload an alarm or lockout signal to the remote monitoring center according to the pre-set threshold, or directly activate the alarm or lockout device. The upper computer software can sample and store monitoring data according to the set time and frequency, and automatically plot the above data into a trend chart as needed for observation and analysis.
The application of SF6 gas comprehensive online monitoring technology can realize the status monitoring of circuit breakers, which is conducive to timely grasp of equipment
The operational status ensures the safe and stable operation of the power system, enabling state maintenance to be achieved, reducing maintenance costs and power outage time, thereby improving management level.

(3) Structure *, easy to install and use
The monitor adopts a fully enclosed design, with a beautiful appearance. The sensor, power supply, data output circuit, and monitoring display are installed in the same casing, directly displaying the volume ratio value of water content (some models of transmitters). It is waterproof, dustproof, explosion-proof, resistant to strong electromagnetic interference, easy to install and use, and can be used in high-frequency electric field environments and outdoor environments.
