MEMS Digital In-Place Inclinometer System


RST的新, MEMS Digital In-Place Inclinometer (IPI) System is designed to reliably measure lateral movement in and around dams, 堤防, 垃圾填埋场, 山体滑坡, 桩, 皮尔斯, 挡土墙, 和牙, particularly when continuous remote monitoring is required. It provides an early warning 为 movements, essential 为 protecting life and equipment.

Each IPI employs MEMS accelerometer sensors housed inside a 28.6 mm (1.125 in.) diameter, watertight, stainless steel enclosure. The sensor body is rigidly connected to a 25.4 mm (1.0 in.) diameter bay rod which establishes the length of the IPI. Multiple IPIs are assembled with pivots allowing 为 sensing of displacement over discreet, configurable intervals. Wheel assemblies centralize the pivot point and establish the azimuth of each IPI. They are available in sizes to fit 70 mm (2.75 in.)或85毫米(3.34 in.) O.D. inclinometer casings.

The sensors are read through a connectorized signal cable designed to chain together multiple sensors. A data logger is used to monitor the deflection of each sensor on the digital bus. If necessary, an alarm can be triggered when movement reaches a threshold rate or magnitude.

Designed 为 ease of installation, serviceability and fast delivery, RST’s In-Place Inclinometer System comes standard 为 both biaxial and uniaxial in one model.

Speak with an Expert

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network 为 the first time. They delivered everything within the tight project time frame to ensure that t在这里 were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
