FIELD DATA ACQUISITION
Sigra has for some time had to have reliable field data acquisition systems for its own operations. These systems have a general value to anyone wishing to gather data. As a consequence Sigra has made available for sale some equipment and also provides a field data acquisition service. Telecommunications advances mean that the data gathered can be transmitted almost anywhere.

Field Services
Sigra can provide and install field data acquisition services using its field data logger or two wire system. These systems can be used to monitor field sensors ranging from geotechnical to environmental. In some instances Sigra will provide a field data service gathering and supplying information to a client.
In specific applications Sigra can supply a control function with its instrumentation. This may be used to operate a pump, turn on a valve etc.
Potential applications are wide and include the monitoring of landslide sites, gas reservoirs, gas well flowmeters, settlement around excavations, stream flow and other environmental sensors.
