Abstract

The invention relates to a Newtonian liquid viscosity on-line measurement signal acquisition device. The device is characterized in that the Newtonian liquid viscosity on-line measurement signal acquisition device is a bypass pipe structure externally connected to the lower part of a solution tank of a measured Newtonian liquid; and the bypass pipe structure is composed of a pump fluid bent-tube section and a viscosity online measuring signal collecting pipe section, a liquid returning bent-tube section, and a temperature control circuit system and a pump fluid speed regulation circuit system.A cross stress sensor of the Newtonian liquid viscosity on-line measurement signal acquisition device is limited in the center of a liquid guiding straight pipe; an electric infusion pump makes a to-be-measured Newtonian liquid flow through the cross stress sensor towards a direction with a constant flow rate, so that the flow velocity of cross stress sensor is true relative to the to-be-measuredNewtonian liquid, and the viscosity resistance of the to-be-measured Newtonian liquid to the cross stress sensor is true, and thus, the measurement accuracy is high.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an on-line measurement signal acquisition device for Newtonian liquid viscosity. Background technique [0002] At present, there are two working forms of the sensor in the traditional Newtonian liquid viscosity online measurement signal acquisition: one is the viscosity sensor rotation type, and its working principle is that the viscosity sensor is immersed in the liquid to be measured, and the sensor is driven by the motor to rotate. Rotating in the liquid, due to the viscosity of the liquid, the sensor will encounter resistance when rotating in the liquid to be measured. At a certain speed, the greater the viscosity, the greater the resistance, and thus the greater the output voltage of the sensor. The other is the swing type of viscosity sensor. Its working principle is that the viscosity sensor is immersed in the liquid to be tested, and the sensor swings back and forth in the liquid t...
