Time detection sediment probe inclination angle and transmit to sediment probe control unit, control unit by inclination angle transmit to ground host machine；
Step (b): ground host machine judge inclination angle whether more than the probe tilt threshold preset, if it is, carry on slowly heavy
Slag is popped one's head in, until the inclination angle of sediment probe is less than probe tilt threshold, cable reel stops promoting；If it does not, proceed to step
(2)。
Pressure of the present utility model-inclination angle type sediment calibrator passes through Simultaneous Determination probe inclination angle and probe pressure, both
It is mutually authenticated, improves reliability and accuracy that under sediment, separating surface judges.Meanwhile, electric machine assembly is pacified side by side with probe assembly
Dress, drives probe to move back and forth by gear mesh engagement, substantially reduces the length of probe, is conducive to increasing probe stroke, increases
Add sediment thickness detection range ability；Probe movable sealing uses the forced sealing of lip to seal with O type and combines, and improves probe
The reliability of waterproof sealing；Motor working current is equivalent to probe pressure, simplifies sonde configuration, improve probe work
