Questions Buyers Ask
Monitoring Instruments Questions
What is the difference between a traversing probe and an in place string
The probe is lowered through the casing to build a profile on each visit at 0.001 degree resolution. The in place string stays in the hole and reports continuously over RS485 at 0.0005 degree resolution.
What pressure ranges do the cells and piezometers cover
Ten steps from 0.1 MPa to 6.0 MPa, with a 0 to 1.0 MPa micro earth cell that can be customised.
Can instruments measure temperature as well
Yes. Piezometers and strain gauges can measure the temperature of the buried point, with accuracy of plus minus 0.5 degrees C.
Are the probes suitable for water filled holes
The inclinometer probes are rated IP68.
How do we identify an instrument after a cable break
An identification recognition function can be added so the original instrument code can be found after disconnection.
Do you supply casing to match the instruments
Yes. Inclinometer casing in ABS, PVC and aluminium and PVC piezometer casing in OD 53, 70 and 80 mm.
