CJ-1 Smart Hydraulic Settlement Gauge with RS485 Output for Long-Term Deformation Monitoring
CJ-1 Smart Hydraulic Settlement Gauge is designed for long-term settlement monitoring inside and outside engineering structures. It is widely used for dams, bridges, slopes, foundations, highway embankments, civil and industrial buildings, and internal or external settlement deformation monitoring of backfill soil. The hydraulic settlement gauge is composed of a silicon pressure sensor and supporting accessories. It can be installed as a single monitoring point or used in multi-point networked measurement systems. The sensor body adopts a full stainless steel structure with compact 24 x 136 mm size, impact resistance, grounding lightning protection and stable long-term operation.
