2) Connect the first length of gauge tubing to the bottom wheel assembly. The length of tube is
shown in the table supplied with this manual. (In some cases, two tubes are joined together
by a special union.) Use the 10-32 screws and nuts, and a thread locking cement to make this
joint.
3) The next step is to attach the uniaxial or biaxial sensor assembly.
2.2.1 Uniaxial System
The uniaxial sensor is delivered unattached to its wheel assembly and should be attached
using the two 10-32 nuts and cap screws supplied. The tongue of the sensor fits inside the
slot of the wheel assembly with the orientation set such that the A+ direction marked on
the sensor is aligned on the same side as the fixed wheel on the wheel assembly. Tilts in
the positive direction yield increasing readings in digits.
Vibrating wire tilt sensors are shipped with a clamp screw holding the internal
pendulum mechanism so that it is not damaged in shipment. A label is attached to
each sensor emphasizing the importance of removing the slotted-head clamp screw
completely and replacing it with the Phillips-head seal screw taped to the sensor.
(Extra seal screws are provided in a zip-lock bag along with other accessories in case
some become lost). This is very important for the sensor to be able to respond to
tilting and remain waterproof.
The sensor and wheel assembly is now attached to the first tube section using a single
long 10-32 cap screw. (Use Loctite 222 on all threads.)
