Automatic monitoring system for soil heat flux

Product Details

I. Overview
Soil heat flux is a reflection of the heat exchange between the surface and deep layers of soil, and is an important component of surface energy balance. The magnitude and positive negative transformation of soil heat flux directly determine the balance of soil heat, control the evaporation and respiration of soil moisture, and affect the growth and respiration of plant roots, as well as the absorption of nutrients and water. The measurement of soil heat flux is of great significance for the formation of soil ecological environment, agricultural production, and engineering construction.
The JZ-KJR soil heat flux monitoring station is an instrument developed and produced by our company for measuring soil heat flux. This instrument has the characteristics of simple operation, strong anti-interference ability, high measurement accuracy and reliability. It can display real-time soil heat flux instantaneous value, hourly cumulative measurement, daily cumulative measurement and other measurement data. It can also output data and generate reports using computer management software, which can meet the needs of scientific research, agriculture, teaching and other related work.

Product composition: Soil heat flow sensor, JZ-2R heat flux recorder and testing system analysis software, communication system and power supply system, etc. (Note: If sensors are added, please communicate by phone in advance.)

Application areas: Widely used for soil heat flux measurement in agriculture, forestry, construction, research institutes, quality inspection departments, industrial sites, agricultural greenhouses, and material research.

2、 Product Features
1. This instrument is designed to measure soil heat flux, and all software operations are calibrated without the need for traditional manual adjustment. It overcomes the zero drift and time drift of operational amplifier components.
2. Large screen LCD display. The display methods include Chinese character display and graphic display, and the display content includes instantaneous heat flux value, hourly cumulative measurement, daily cumulative measurement, date, and time. It can display multiple temperatures on one screen and replace microcomputers for real-time observation, achieving dual functions of simultaneous monitoring with microcomputers and independent monitoring by disconnecting microcomputers.
3. Using high-performance microprocessor as the main control CPU and large capacity data storage, it can continuously store data for more than 3 months. The storage time can be set according to the user's required collection density. With a touch of the thin film button, the operation is simple and real-time observation of various heat flow data can be achieved.
4. It has power outage protection function. When the AC power is cut off, it is powered by the storage battery and can be maintained for more than 72 hours, achieving data loss and uninterrupted monitoring.
5. Standard RS232 interface, can be connected to a computer, real-time transmission of collected data, generation of reports, and automatic printing of detection reports when connected to a printer. At the same time, wireless communication methods can be selected based on the user's specific usage situation to achieve communication without distance limitations.
6. All templates adopt the structure of STD industrial control machine, which has all the advantages of STD industrial control machine. They all use CMOS devices, with low power consumption, strong anti-interference ability, and high reliability. Portable shockproof structure, suitable for use in harsh industrial environments.
