HCDAR-51 Solids, Powders, Liquids
Application: Solids, Powders, Liquids
Signal Output：（4～20）mA HART
Explosion-Proof Grade：Exia IIC T1-T6 Ga
The electromagnetic impulse travels along the steel cable or bar at the speed of light. When it encounters the surface of the measured medium, part of the impulse will be reflected to form an echo and returns to the impulse launcher along the same path. The distance between the launcher and the surface of the measured medium is proportional to the propagation time of the impulse, then we can get the height by calculation.
H = H - v * t / 2
( In the formula) ： h→( level of material)
H→height of empty status(total height)
V→ Radar wave speed(approximately to light speed 3*108m/s)
T→Time interval between wave emitted and received
Guided wave radar level transmitter mainly consists of housing shell, PCB, operation and display panel, flange, antenna, sensor and etc.
3.1 The electromagnetic waves emitted are constant and do not require field verification or migration to change the range.
3.2 Various installing methods, can be connected by thread or flange.
3.3 Changes in temperature, pressure and density have no effect on the measurement.
3.4 There are no moving parts during the measuring process, no mechanical parts damaged problems, free maintenance.
3.5 Almost any liquid or stationary particle medium can be measured.
3.6 The disadvantage is there are blind zones at the top and bottom. The minimum dead zone on the top is 0.25m.
HCDAR-51 has common cable type antenna structure, the measuring range could reach to 30m, loop power supplied by two wire 4-20mA at 24V DC under the HART communication protocol.
HCDAR-51 radar manufactured by our company can be used in solid powder liquid measurement.The picture shows my company's products installed in a feed factory 18 meters above the warehouse.The site situation is complex, and there are a lot of steam pipe interference and internal cross beam. After the site situation is confirmed, our company chooses hcdar-51 radar to solve this problem, and the site use is stable and has been praised by users.
