Real-time automatic viscosity measurement management system contributing to cost reduction.

basic information

The automatic viscosity measurement system from Opticara is designed for use in production lines. 【Features of the Sensing Method】 ■ Sturdy housing with pressure-resistant explosion-proof specifications ■ Relatively unaffected by external disturbances ■ Adopts a rotary sensor that detects changes in the rotation speed by rotating a disk in the solution ■ Resolution of 0.25 to 0.5% 【Features of the Controller】 ■ Compact design ■ Easy operation via the display panel ■ Automatic addition function for diluent solvents ■ Standard applications allow selection of usable scales and key control parameters ■ There are types that can evaluate and control temperature values as well ■ Analog output, alarm output, multi-valve control ■ 200V or 100V AC power supply

Detailed information

• 

  This is a basic configuration diagram. A rotary sensor is inserted into the product material viscosity to measure viscosity in real time.

• 

  The measurement principle reads the change in resistance of a rotating sensor inserted into the measured viscous medium.

  Please take a look at the Zahn cup viscosity curve graph provided by Opti-Color. The vertical axis of the graph represents the drop time in seconds of the Zahn cup, while the horizontal axis indicates the CP viscosity. Each curve is labeled with the abbreviation of the measuring container. Typical examples include Rig3: Cup 3 from the Rheo Company, Rig4: Cup 4 from the Rheo Company, z2: Zahn Cup 2, and z3: Zahn Cup 3. In Japan, we recommend Cup 3 from the Rheo Company, which is similar to the curve of Zahn Cup 2 (for overseas use). Please confirm that Rig 3 and z2 intersect at the red box 1. It can be seen that the steeper the curve, the smaller the variation in CP viscosity, while conversely, the gentler the curve, the larger the range of variation in CP viscosity. Cups with gentler curves experience significant viscosity changes due to short time variations, requiring considerable skill from the field operators. For example, "Zahn Cup 3" corresponds to the z3 curve. A change of just a few seconds can result in CP viscosity fluctuating by several tens of times, making measurement extremely difficult. It is clear that as the viscosity of the fluid handled in the field increases, the error in time measurement by the cup also increases, directly leading to losses in fluid materials (higher product costs).
