● Laser or high power infrared light source
● Computer image processing technology
● Fully automatic closed-loop control technology
● High precision, high performance and easy maintenance
Installation location
The OD measuring instrument can be installed before the cooling water tank or after the water tank. When installed in front of the water tank, because the measuring head is close to the extruder, the feedback control is timely, and the best control effect can be obtained, but the plastic has not been solidified, and the set nominal value should be properly corrected. When installed behind the water tank, the measured actual value of the outer diameter of the cable is relatively accurate and reliable, but the control lag is large and the control effect is slightly poor. In addition, it should be noted that the cable to be tested should be blown dry, otherwise the water film outside the cable will affect the measurement accuracy. In actual use, the nominal value should be appropriately increased according to the degree of water with the measured object.
