Based on the newLight® technology, FS61DSP Displacement Sensor is a ruggedized Fiber Bragg Grating (FBG) sensor designed to measure linear displacement on different types of structures. The sensor uses two FBGs in a push-pull configuration for effective temperature compensation. With the development of fiber optical technologies, fiber Bragg grating (FBG) sensors are frequently utilized in structural health monitoring due to their considerable advantages, including fast response, electrical passivity, corrosion resistance, multi-point sensing capability and low-cost. The traditional vibrating string displacement gauge is easy to install and has a high detection accuracy; however, it has the disadvantages of a low sampling rate, single sensing information, and susceptibility to electromagnetic interference.

Barrel temperature should be set 10°C above the melting point, typically 140-220°C depending on PE grade and melt flow rate. “PE shrinkage is anisotropic—higher in flow direction. Set it correctly, and you get glossy surfaces, proper dimensional stability, and consistent part quality. We've found that understanding PE's unique characteristics is. For most production applications, mold temperatures of 40–65°C balance crystallinity and shrinkage acceptably. Gate selection is particularly important for HDPE. Direct sprue gates are a common source of warpage — the high stress concentration at the gate, combined with HDPE's strong directional. Getting both into the correct range for the material is essential for all manufacturers, because injection moulding at the incorrect temperatures can have a significant impact on the final product, including the appearance and strength of the part. Plus, I'll share the insider tips that most manufacturers won't tell you.
