Double tube probe design, the first in China;
High detection sensitivity, minimum allowable medium density of 0.02g/cm³, suitable for most solid particles;
High temperature design, the process temperature can reach 250℃, and the ultra-high temperature type (gas/water cooling) process temperature can reach 400℃, the industry leading;
Rich self-diagnosis function, can accurately locate fault information;
Effectively prevent hanging, avoid false alarm, simple installation, no need to calibrate;
The use of strong corrosion resistance materials: 316L, 318S13.
LSF04 vibrating bar level switch is suitable for the measurement of granular solid level, such as: PVC, sodium hydroxide, lime, cement, sand, soil, coal, dust, flour, sugar, salt, grain, beans and other materials measurement.
