Figure 4 – Uniaxial or Biaxial Tiltmeter Installation Details
2. Now, the uniaxial or biaxial tiltmeter sensor may be installed. Attach the tiltmeter housing to
the mounting bracket using the supplied 10-32 cap screws, washers and nuts. Do not tighten
the cap screws yet. Attach a portable readout such as the RB-500 (see Section 3 for readout
instructions) and observe the reading. Adjust the sensor in the slot of the mounting bracket
while observing the readout until the tiltmeter reads within
0.15 volts of the zero reading as
shown on the calibration sheet (sample, Figure 8) supplied with the sensor. When the desired
reading is reached, tighten the cap screws to secure the tiltmeter in place. Check the reading
again after tightening to make sure it still reads within
0.15 volts of the zero reading.
If the tiltmeter is installed in an exposed location in a construction area and/or if the
installation is in direct sunlight it should be covered with a protective enclosure and/or
insulation.
With a biaxial sensor the second, (B), MEMS sensor is included in the housing and is
attached with its positive direction 90° clockwise from the positive direction of the first
sensor (looking downwards in plan). Adjustment of the zero reading for the B sensor is
accomplished by loosening the 3/8-16 nut and rotating the Mounting Bracket.
