Instrument Life Are readings needed only during construction or will they be needed
for years afterwards. Instruments, signal cables, and protective mea-
sures should be selected accordingly. Some instruments are
excellent for short-term applications, but may exhibit excessive drift
over the long term.
Environmental Conditions Temperature and humidity also affect instrument choice. Instruments
such as hydraulic piezometers and liquid settlement gauges have
limited use in freezing weather. In tropical heat and humidity,
simple mechanical devices may be more reliable than electrical
instruments.
Personnel and
Resources at the Site
Consider the personnel and resources at the site when choosing
instruments. Do technicians have the skills required to install and
read a particular type of instrument. Are adequate support facilities
available for maintenance and calibration of the instrument.
Data Acquisition An automatic data acquisition system may be required when:
(1) there is a need for real-time monitoring and automatic alarms;
(2) sensors are located at a remote site or in a location that prevents
easy access; (3) there are too many sensors for timely manual read-
ings; or (4) qualified technicians are not available.
If a data acquisition system is required, the choice of instruments
should be narrowed to those that can be connected to the system
easily and inexpensively.
