Wireless host

System introduction

Wireless temperature measurement system is made up of wireless temperature measuring host, wireless temperature sensor and software. It is a high-tech product for real-time monitoring of temperature.

The wireless temperature sensor is used in the front of the wireless temperature measuring system, which can be quickly and conveniently installed on the contact point of the high voltage charged body to accurately track the temperature change of the heating connection. The wireless temperature sensor is safe and reliable by transmitting the temperature information by using the radio frequency technology, and realizing the equipotential of the collector and the collected point. The acquisition terminal of the wireless temperature measurement system can accurately report the temperature rise of the easily heating components of all the high voltage equipment in the operation, and provide reliable data basis for the safe operation of the equipment. When the temperature of the measured point exceeds the predetermined threshold value, the alarm signal will be sent out to remind the person to take measures in time; the monitoring and operation software is powerful. The system can display the geographical distribution map, the operating parameters of the contact temperature, the warning information, the historical parameters and so on through the graphics, tables, curves, ellipsoid and so on through the human-computer interface, providing the most direct and reliable data basis for the decision layer, eliminating the hidden dangers and minimizing the reduction of accidents.

System characteristics

1. itself has a display screen, which can display the temperature changes of different probes. When the temperature exceeds the critical value, it can sound and light alarm and display the location of hot spots.

2. has the standard RS - 485 communication interface, which can realize remote online monitoring and facilitate users to check the temperature changes at any time.

3. with four relay output (tripping, alarm, fan, heating), according to the specific function of flexible settings

4. installation of strong anti electromagnetic interference design, safe, reliable, high accuracy.

5. super long battery life, up to 3~5 years; battery replaceable.

6. free application free band, micro power

7. no hidden danger: wireless acquisition, no creepage, safety.

8. standardized design, which can be easily interconnected with other systems, with low cost and flexible installation.
