Moisture/humidity sensor is an instrument widely used in fields such as water-saving agricultural irrigation, greenhouses, flowers and vegetables, grassland pastures, soil quick testing, plant cultivation, and scientific experiments. Name: Soil moisture/humidity sensor Model: FDS-100 Measuring principle: FDR frequency domain method .unit:% . Probe Material: Stainless Steel Sealing material: Epoxy resin Measuring accuracy: ±3% Operating temperature range: -40°C～85°C Working voltage: 7 ~ 24V Operating current: 25 ~ 35mA, typical value of 28mA Measuring frequency: 100Mhz .output signal: Voltage type 0 to 2V DC Current type 0～20mA Measuring stability time: 2 seconds Response time: <1 second Measuring area: centered on the central probe, a cylindrical body with a diameter of 7 cm and a height of 7 cm surrounding the central probe . Cable length: 1.5 meters (standard) The sensor is small and compact design, easy to carry, simple installation, operation and maintenance. .The structure design is reasonable and the lifespan of the stainless steel probe is guaranteed. The outer part is encapsulated with epoxy resin and has good sealing property. It can be directly buried in the soil and is not corroded. The soil effect is small and the application area is extensive. High measurement accuracy, reliable performance, ensure normal operation. . Fast response and high data transmission efficiency. Widely used in fields such as water-saving agricultural irrigation, greenhouses, flowers and vegetables, grassland pastures, soil quick testing, plant cultivation, and scientific experiments. Reference editing area The Milling Machine was originally a horizontal milling machine created by American E. Whitney in 1818.In order to mill the spiral groove of the twist drill, American J.R. Brown created the first universal milling machine in 1862, which is the prototype of the milling machine for the lifting platform.The portal milling machine appeared around 1884.Semi-automatic milling machines appeared in the 1920s, and the workbench used the stops to perform automatic conversion of [feed-fast" or [fast-feed".After 1950, milling machines developed rapidly in control systems, and the application of digital control greatly improved the automation of milling machines.Especially after the 1970s, the digital control system and automatic tool change system of the microprocessor were applied on the milling machine, which expanded the processing range of the milling machine and improved the machining accuracy and efficiency.As the mechanization process intensified, CNC programming began to be widely used in machine tool operations, which greatly released the labor force.CNC programming milling machines will gradually replace manual operations.The requirements for employees will also be higher and higher, and of course the efficiency will be higher and higher.
