Structure of the equipment
Densitometer PLOT-3B measures the density of oil product temperature on all height of the tank and commercial water.
Converter electronic PE-6 is intended for reception of information from the PLOT-3B densitometer, control of the servo-driver, measurement of level and mass of oil product.
The SP-1 servo-driver is intended for movement of the PLOT-3B densitometer in the vertical direction with the set movement speed down and up. It consists of a stepper motor, worm gear, drum, which turn to turn keeps the cable at the end of which is suspended densitometer PLOT-3B and the position and tension sensors.
