SJ – 2150\/2100 is equipped with coil housing with gauge and magnetic coil connected with stainless steel tube and flange in waterproof and anti-corrosion. SJ – 2150\/2100 contains stainless steel tube and gauge and magnetic coil in waterproof and anti-corrosion. The vibration sensor has excellent responsiveness and reproducibility and is almost not affected by secular change, so it is most suitable for long time measurement.<\/p>\n\n\n
