LY401 wireless temperature measuring device consists of wireless temperature measuring device host and wireless temperature measuring sensor. Wireless communication transmission is adopted between the host and the sensor. The sensor is installed on the high-voltage equipment, and there is no electrical connection with the host of the wireless temperature measuring device. The device solves the problem that the operating temperature of the electrical contact of the high-voltage equipment is not easy to be monitored online in real time. LY401 wireless temperature measuring device has strong electromagnetic interference resistance and can be used in the environment of high voltage, large current and strong magnetic field. The wireless temperature sensor is small in size, effectively solving the problem of space limitation.
Features:
◇ It has the advantages of anti-interference and dustproof.
◇ It has the function of recording the sequence of alarm events.
◇ The host of the wireless temperature measuring device is panel mounted with color LCD display, and the sensor address can be set locally.
◇ The wireless temperature sensor can be directly installed on the outdoor knife switch or transformer of each high-voltage switch bus connector.
LY401 wireless temperature measuring device, for typical networking mode
◇.Monitor the current temperature of the measured point in real time.
◇ Real time clock is displayed and used as the time benchmark for event recording.
◇ Over temperature alarm, three-phase temperature imbalance record.
◇ The host of the wireless temperature measurement device receives the temperature data of the wireless temperature measurement sensor and uploads it to the background system.
◇ The protection parameters and sensor addresses can be set locally through the human-computer interface.
◇ User password management function.
Main functions of wireless temperature measuring device host
Main functions | Function introduction |
Basic functions | Receive data | Receive the temperature and sensor working voltage uploaded by the wireless temperature sensor |
Display Data | Color display of received data, more intuitive display effect, controllable backlight switch, suitable for a variety of application sites |
Clock display | Real time clock display and serve as the time benchmark for event recording |
Parameter setting | All parameters are flexible and can be set, easy to operate, and power failure data will not be lost |
Alarm output | When an alarm event occurs, the relay dry contact signal will output and send out a buzzer alarm sound prompt |
Advanced Features | Limit temperature record | Record the highest temperature and lowest temperature of each temperature measuring point monthly, and record the corresponding power supply voltage and occurrence time. When it is used for more than one year, the monthly data of the previous year will be automatically covered |
Temperature alarm record | Record the temperature, start time and end time of each phase at the temperature measurement location where the alarm has occurred. Up to 100 records can be saved. When there are more than 100 records, the earliest record will be automatically overwritten |
Temperature unbalance record | When the three-phase temperatures of the same group of temperature measuring positions are not equal, record the temperature and occurrence time of each phase of the current group monthly, and calculate the imbalance. When used across years, the monthly data of the previous year will be automatically overwritten |
Password management | Password management mode is adopted. Password must be entered when setting parameters. The password is divided into user password and system password. Entering the system password can perform more advanced and setting functions |
