TQ-812 Top mounted Rotary Viscometer

product overview：

The TQ-812 series online viscometer is a rotary viscometer that uses coaxial cylinders of different shapes as the measurement system. The essence of the measurement is to produce shear on the gap (measurement gap) in the cylindrical system.

The constant angular velocity is driven by the drive device (rotor) of the viscometer to rotate the measuring unit (through magnetic coupling or rigid rod), and the applied torque rotates the measuring unit in the measured fluid to determine viscosity. This torque is proportional to the angle of deflection of the torque sensor and is converted into a 4-20 mA electrical signal output by the sensor.

The 4-20 mA signal output is processed by an electronic unit and can be used for direct display, recording, and control of rheological parameters viscosity.

matters needing attention:

Due to the requirements of the production process, it is often installed on sites with harsh working conditions. In order to minimize the severity of the working conditions of the viscosity sensor as much as possible.

1. Viscosity sensors should be installed as much as possible in places with small temperature gradients and changes, without impact or vibration.

2. The measured medium must not freeze, otherwise it will damage the sensing element and cause damage to the density sensor.

3. Prevent contact with corrosive or overheated test media.

4. To prevent debris from depositing inside the sensor body.

5. Handle with care to prevent damaging the sensor
