VW Temperature Sensor, 2012/6/20
Installation Suggestions
Handle the sensor carefully. Never let vibrators make contact with the
sensor or the cable.
When a temperature sensor is mounted in a particularly vulnerable
position, consider spraying the area with marker paint, covering the
gauge with a protective wire mesh, or placing some non-structural
steel to protect the gauge. Damage is most likely to occur when the
reinforcing gauge is lifted and then placed and also when the tremie
pipe places the cement.
Mark cables before installation to help you identify the sensor and
cable at the end of the installation process. Add extra identification
marks at locations where the cable is vulnerable or must be spliced.
This precaution may make it possible to reconnect a bundle of broken
cables. Also add extra marks toward the end of the cable, where
excess cable length may be cut off.
Start with the sensor farthest from the readout station and run the
cable along the reinforcement, picking up cables from other sensors
along the way. Use nylon cable ties to strap the cables to the reinforce-
ment at least every 300 to 400 mm.
Run cables along the underside of any reinforcements gain some pro-
tection from the poured concrete and the use of vibrators. Never run
cables diagonally or unsupported through the reinforcement.
Leave sufficient slack in the cables where there is likely to be any
movement in the reinforcement. Check that slack cable cannot be
damaged.
Protect the cables where they exit the concrete with a short length of
conduit.
