-Installation position

DDM – 2020 diameter measurement and control device can be installed before the cooling water tank, also can be installed after the sink. When installed before the sink, the measuring head near the extruder crosshead, timely feedback control, can get the best control effect, but has not yet solidified plastic, nominal value NO. should be set by the appropriate amendment.

Were measured after installed in the sink, is the actual value NO. of the cable diameter, more accurate and reliable, but the large amount of lag, the control effect is a bit poor. In addition must pay attention to, cable under test to dry, or cable outside water film will affect the measurement accuracy and practical use should be the analyte according to the degree of water, appropriate increase in nominal value NO.
