Ground Vibration Measurement
The MENHIR (Modular Enhanced Intelligent Recorder) from Semex Engcon measures vibrations and shocks in an efficient and secure way. It makes complex tasks in structural dynamics, structural and vibration monitoring easy with customised solutions.
All of these areas require robust equipment with high reliability recording, data transfer and analysis to handle high demands. MENHIR, in conjunction with the SDC software (Smart Data Center) specially developed for this purpose, guarantees secure collection, transmission and data analysis as a total solution.
MENHIR’s simple and intuitive operating concept allows anyone with minimal training to work successfully and quickly with the system.
FULL ACCESS. FULL CONTROL
The SDC Smart Data Center offers a fully integrated Cloud Solution to provide full access to your data and device status anytime, and, if desired, to the standard-compliant analysis of the data. Access your data quickly and easily from your PC, tablet or smartphone to. It requires no effort to set up access.
Scale according to your needs
Whether you manage only one measuring point or dozens, MENHIR makes it easy. The innovative cloud solution “Smart Data Center“ (SDC) Basic is included as an integral part of MENHIR system. An optional complete analysis module is also available providing a tool for effortlessly comparing to all common standards. Reports may be configured to your liking, automatically generated and transmitted electronically in free adjustable intervals.
An internal SIM card slot available. The additional, external SIM card slot, allows you to determine at any time, without opening the device, which provider transmits your data. Your MENHIR may also be equipped with with an optional, inexpensive M2M solution.
No power at the job site? Never mind, MENHIR’s internal battery provides up to 48 hours operating autonomy, depending on transmission requirements.
The innovative measurement concept allows you to place the MENHIR with up to 15 ° offset on the ground. MENHIR detects the offset and corrects it automatically. You can also align the device exactly with the three, integrated levelling screws. No mounting platform is required.

Downhole Sensor clamping mechanism
The downhole sensor uses a movable eccentric disc mechanism for clamping the sensor towards the guidance (inclinometer) tube. This allows clamping and recovering the sensor at a specific depth.
The inclinometer tube must be correctly oriented (notch towards north) and solidly mounted (concrete) into the ground.
