By using microwaves SlideControl measures the distance between the flowing material surface and the sensor and thus the filling height of the flowing material on the tissue.
This filling height is provided as 4 … 20 mA signal.
If it comes to a standstill or demolition of the conveying, the output signal immediately drops to 4 mA, even if the material is still in the slide.
It is possible to generate with the slide wide a trend signal for the flow rate, if the flowing density is known:
Q = H x B x ρ x v
Q = Flow rate
H = Filling height
B = Slide wide
ρ = Fluidized density
v = Velocity
The velocity of the material flow is assumed to be constant.
Parameters as the slide wide or the density of the material are typed into the transmitter by software.
SlideControl consists of a sensor, the associated transmitter and a mounting kit.
The maximum distance between sensor and transmitter may be up to 300 m.
The sensor doesn’t need any additional auxiliary power supply. It is powered by the transmitter.
The associated transmitter is available as DIN rail version or in a field-enclosure with display.
The mechanic installation occurs through the mounting plate, which has a 1 ½“ process connection for the sensor and a second closable opening for inspection and calibration purposes.
