929 wireless temperature device
929 wireless temperature measurement device is a temperature data collection terminal products by our company's independent research and development, with the wireless temperature sensor and temperature monitoring station, they form a complete set of wireless temperature measurement system. The 929 wireless temperature measurement terminal installed in the switchgear or engine control room, is responsible for receiving the wireless temperature sensor sends out the temperature data, and connected by RS485 bus, upload the data to the workstation computer of temperature monitoring, and response to various control command by computer.
Brief introduction of 929 wireless temperature measurement system
929 wireless temperature measurement system is a kind of temperature measurement system that developed by our company, which is accurate, reliable and easy to install. It adopts advanced sensor technology and unique advanced wireless communication technology for high voltage isolation and signal transmission, and uses the insulativity and resistance performance of electromagnetic interference to its inherent, fundamentally resolved the problem of contact’s operating temperature is not easy to monitor in high voltage switchgear.
The system is suitable for various types of high voltage equipment temperature on line monitoring, with characteristics of reliable high voltage isolation, resisting strong electric field and magnetic field interference, and good thermal stability. Through the real-time monitoring of the temperature of switch and contact, this system can found abnormal heating fault signs, thus prevent the fault, and the through temperature history, to provide scientific data for "condition-based maintenance” of switchgear. This system has an important significance to the safe operation of the switchgear and other electric equipment.
929 wireless temperature measurement system is mainly composed of three parts: the temperature front-end acquisition device (temperature sensor), wireless temperature measurement terminal, temperature monitoring station (or automatic background), as shown in figure 1-1. After 929 wireless temperature sensor making temperate measurement to temperature monitoring point, the temperature data is transmitted through wireless transmission to the wireless temperature measurement terminal; Through the bus connection, temperature monitoring computer gather temperature data of each monitoring point from the wireless temperature measurement terminal, for a long time stored in the database, real-time display the temperature variation curve of monitoring points, and make the analysis, once found overheating or temperature sharp rises to the preset temperature alarm value, then immediately give an alarm. At the same time, it can be convenient to access the temperature data in the upper computer to network, proceeding Web release. The temperature measurement terminal can provide a temperature alarm value of two grades; the temperature exceeds the alarm setting value, and can drive relay and buzzer. The application of the system is divided into civil and industrial use. Civil application is mainly applicable to room temperature monitoring; industrial application is mainly used in electric power, steel, petrochemical and other fields, it can perform the temperature real-time monitoring for high voltage cable connector and high-voltage switchgear contact, help operation and maintenance personnel to master the operation condition on site.
Brief introduction of 929 wireless temperature sensor
929 wireless temperature sensor is a temperature front end collection device researched and developed by our company, consists of the main control chip (MCU), wireless data transmission, digital thermometer and the power supply battery; Aluminum alloy package, grit-blasting process, beautiful and generous. After 929 wireless temperature sensor measuring the temperature, it transmits the temperature data through wireless transmission to the wireless temperature measurement terminal. 929 wireless temperature sensor is installed on the cable connection, the surface of the transformer and the switch connection, which the temperature is easily get rise. Each wireless temperature sensor has a unique ID number, it needs to record the installation site of each sensor when actually install and use of the sensor, and input the computer database of temperature monitoring workstation with ID number.
Functions and characteristics:
Low power consumption and long service life.
High sensitivity and long transmission distance.
Compact size and easy to install.
High precision temperature measurement chip with contact temperature sensing, makes measuring temperature more accurate.
The wireless transmission mode reduced the trouble caused by routing.
Timely and accurate temperature alarm mechanism provides users security.
Brief introduction of 929 type wireless temperature measurement terminal
The 929 type of wireless temperature measurement terminal is a temperature data acquisition terminal product which is researched and developed by our company independently. It works with the wireless temperature sensor and temperature monitoring station. All these three parts constitute a complete set of 929 wireless temperature measurement system. The 929 type wireless temperature measurement terminal installed in the switchgear or control room is responsible for receiving the wireless temperature sensor sends out the temperature data. And through the RS485 bus connection, it can upload the data to the temperature monitoring station computer and respond to the computer's various control commands. In the absence of the background computer, the terminal can also work independently and achieve the super temperature alarm or protection function.
Functions and characteristics:
High sensitivity of wireless signal sensing
Full Chinese interface, keyboard operation
Two alarm temperature setting threshold, the relay and buzzer can be chosen to drive
Powerful memory function, the storage of 64 sets of super temperature records, the highest temperature of the day, the latest data update time
