The Geotech CPT probes are equipped with individual sensors for point resistance (qc), sleeve friction (fs), pore pressure (u) and a tilt sensor.

The data measured by the sensors is digitised, multiplexed and encrypted with an error detecting code in the probe before it is forwarded to the transmitter or cable adapter for transmission to the surface. To back-up the data transmission, the cones can also be delivered with a back-up memory of 8 hours capacity, with 18 bits resolution on all channels.

The readings from the three channels are corrected for temperature drift by a temperature sensor and a processor in the electronic part of the probe. The probes have therefore a very low temperature sensitivity sensors and with adapters for electric conductivity or seismic CPT. The data measured by the sensors is digitised, multiplexed and encrypted with an error detecting code in.
