JINGTIAN SNB-AI digital display Rotational Viscometer viscosity Detector, standard printer

Introduction

SNB-AI intelligent digital viscometer adopts 16-bit microcomputer processor core control circuit, without gear drive, and has intelligent automatic measurement and manual measurement methods. The blue-screen LCD digital display directly displays viscosity, speed, temperature, percentage torque, rotor number and the maximum viscosity value of the selected rotor that can be measured at the current speed. The sample volume is small, just 10-20ml. Optional "Data Acquisition and Drawing Software" can perform multiple mathematical statistical analysis tasks such as data acquisition, data storage, and historical data comparison. The circuit adopts patch technology, with compact structure and reasonable layout. The measurement performance and functions of this series of products are close to the professional level of similar foreign products.

The instrument can measure the viscous resistance of the liquid and the dynamic viscosity of the liquid. Widely used in the viscosity measurement of various fluids such as oil, paint, food, paper, cosmetics, chemicals, coatings, capsules, etc. Equipped with a special temperature-controlled heater, it can be used to measure the apparent viscosity of asphalt, hot melt, paraffin, medicine, high polymer and other fluids.

Principle

As shown in the figure, the stepper motor is driven with high resolution to drive the sensor pointer, and the rotor is driven to rotate through the hairspring and the rotating shaft. If the rotor is not resisted by the liquid, the hairspring sensor pointer is in the same position as the stepper motor sensor pointer. On the contrary, if the rotor is subjected to the viscous resistance of the liquid, the balance spring will generate torque to counteract the viscous resistance, and finally reach a balance. At this time, the output signal of the photoelectric sensor is sent to the 16-bit microcomputer processor for data processing, and the viscosity value (mPa·s) of the liquid is displayed on the LCD.
