Inclinometer
This measurement type supports Slope Indicator's (Durham Geo-Enterprises's) Vertical In-Place
Inclinometers.
This measurement takes three voltage inputs, AxisA,AxisB, and TempC. The measurement
produces three outputs, AxisA temperature compensated tilt, AxisB temperature compensated
tilt, and TempC in Celsius.
The setup of this measurement type differs based on whether the sensor’s cal sheet lists a
calibration factor named “TOFF”. If the cal sheet for your sensor lists a TOFF property, be sure to
set “HasTOFF” (below) to Yes.
This measurement has the following properties:
Interval, Time
Define when the measurement task runs. (See details under Instantaneous)
HasTOFF
If the calibration sheet for your sensor lists a TOFF parameter, set this property to Yes.
Otherwise, set it to No.
TOFF
This property is displayed only when HasTOFF is Yes. Enter the value of TOFF from the
sensor’s cal sheet.
AC3, AC2, AC1, AC0, AS2, AS1, AS0, AF1, AF0
These properties are coefficients for AxisA, and are displayed only when HasTOFF is Yes.
Enter the values from the sensor’s cal sheet.
BC3, BC2, BC1, BC0, BS2, BS1, BS0, BF1, BF0
These properties are coefficients for AxisB, and are displayed only when HasTOFF is Yes.
Enter the values from the sensor’s cal sheet.
C0_A, C1_A, C2_A, C3_A, T0_A, T1_A
These properties are coefficients for AxisA, and are displayed only when HasTOFF is No.
Enter the values from the sensor’s cal sheet.
C0_B, C1_B, C2_B, C3_B, T0_B, T1_B
These properties are coefficients for AxisB, and are displayed only when HasTOFF is Yes.
Enter the values from the sensor’s cal sheet.
Input Type (AxisA)
Specifies the input type to use for the AxisA parameter of the tilt calculation. This input
type is typically set to Voltage.
Input Type (AxisB)
Specifies the input type to use for the AxisB parameter of the tilt calculation. This input
type is typically set to Voltage.
Input Type (TempC)
Specifies the input type to use for the computing the TempC temperature output, in
Celsius. This input type is typically set to Voltage, and comes by default with a 5
th
order
polynomial defined to convert the voltage input to Celsius.
