The pressure transmitter board is an important part of the pressure transmitter production process, and it plays a key role in the performance, life, stability and other parameters of the entire transmitter. Pressure transmitter board parameters : -25 degrees to +85 degrees, temperature drift: ≤1×10 -4 FS/degree, non-linear error: ≤0.005% FSR. Long-term stability: ≤ 0.05%/year, storage humidity: 90% Application: diffused silicon, ceramic piezoresistive, sputtered film, strain gauges, etc. Magnified chips are products of well-known semiconductor companies imported from the United States Divided into: ordinary type, enhanced anti-jamming, triple lightning protection, digital intelligence.

The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
