*Mainly used in tunnels, highway embankments, and earth rock dam foundations, it can be used for pressure detection of media such as mud and liquids, and can adapt to various harsh working environments. It is a pressure transmitter specially developed and produced for shield tunneling machines. It uses high-precision and high stability pressure cores as sensitive components φ 32 large open dry diaphragms, no filling medium, no pollution risk * resistant to high and low temperatures, corrosion, radiation, and no fatigue creep phenomenon * pressure core with wear-resistant, shock-absorbing rubber pad protection to prevent wear and impact * fully enclosed design, protection level IP67, suitable for various harsh working environments * can output pressure signals while detecting temperature changes in the usage environment
