DGSI MEMS Tiltmeter

DGSI Tiltmeters can be directly connected to a thread or used with an M-Logger. If an M-Logger is being used, please visit the M-Logger Help Article. If the Tiltmeter is directly connected to the THREAD, learn how to add a tiltmeter below.

Adding a DGSI Tiltmeter

Ensure that the THREAD is turned on and connected to the DGSI Tiltmeter directly via one of it's Device ports

1.  Navigate to the Network Module

2.  Press the  button directly on a THREAD to add a Device to it. If your THREAD does not appear here, you may still need to Add Your THREAD as a Connection.

3.  You may also add a device from the button in the Devices & Sensors Section 

4.  Begin by typing in "DGSI Tiltmeter" and select the name once it autocompletes in the search boxScreen_Shot_2017-03-09_at_3.40.13_PM.png


5.  Type in the Connect Code of the THREAD that the Device will be connected to. It will already be pre-filled if the  button on the THREAD was used. 

6.  Next, select the THREAD communication port that the device is plugged into, Device 1 or 2.

7.  Press     to write the settings. Your device should now connect to sensemetrics indicated by a green icon Screen_Shot_2017-03-09_at_3.44.02_PM.png

Sensor Configuration

To start viewing all Tiltmeter calculations, certain setup parameters will need to be entered. Without entering the following parameters, you will be limited to display of raw analog measurements - VoltageA, VoltageB, and VoltageT. 

Navigate to the sensor configuration page of the Tiltmeter you wish to modify 


Sensor Orientation

The X/Y Axis will always be fixed relative to the Tiltmeter's reference indicator (Mounting Stud). The Y+ Axis will follow the mounting stud axis as seen below.

NOTE: Tilt the top of the sensor in the Y+ direction will result in a positive Tilt Y measurement.

Serial Number - Tilt X/Y

Entering the Serial Number of the Tiltmeter will automatically apply the manufacturers calibration factors that are necessary to transform the raw analog sensor values to engineering units (angular tilt). The serial number can be found on the side of the tilt sensor as shown below.

Once serial number is entered,  Tilt X/Y calculations will automatically be available for selection.

Reference Date - 

The reference date will specify the first date used when calculating delta metrics indicated with the ∆

Specify the Reference date to use any ∆ Delta calculations

*Note- If no reference date is chosen, delta calculations will automatically use the first data point in your time range selected as the reference date.

Sensor Azimuth - Northing/Easting

The Tiltmeter does not inherently know North/East. In order for North/East to be correctly represented, you will need to specify the sensor azimuth. This is done by measuring the angle from North to the Reference indicator in a clockwise direction. 

Reference Indicator - The Mounting Stud is the sensors Reference Indicator (Shown above)

Specify the Sensor Azimuth to use Northing/Easting calculations

Structure Azimuth - Transverse/Longitudinal 

This field will allow you to orient the Transverse/Longitudinal Axis in any desired direction. It is useful for finding movement in the direction of a specific structure or any point of reference. See the Structure Azimuth Section on instructions on how to properly set it up.

Specify the Structure Azimuth to use Transverse/Longitudinal calculations

Structure Height - X/Y

Enter the Height of the structure from the base to top of the structure. This will use a trig calculation with the Tilt X/Y angle to create a X/Y Vector at the top of the structure. 

Specify the Structure Height to use X/Y calculations and allow vectors in Map View.
