Abstract:

A consistency transmitter for a pipe carrying a pulp mixture has a sensor blade within the pipe and an arm outside the pipe. The sensor blade is carried by a diaphragm, so the diaphragm is flexed in response to motion of the sensor blade. The arm is connected to the diaphragm so the arm is moved in response to movement of the sensor blade. A blade extends across the diaphragm to constrain the diaphragm to motion in one direction. A probe detects motion of the arm, the circuitry being remote from the probe and connected to the probe by a cable.
