Description

This tool measures fluid pressure and temperature inside the borehole. It integrates dual temperature detectors and dual pressure detectors, spaced 1 meter apart. The differential output provides pressure difference and temperature difference signals.

The temperature sensor uses a high-precision PT100 thermistor powered by a precision constant current circuit. Its voltage drop reflects the borehole temperature, which is then amplified, converted via A/D, encoded, and transmitted to the surface acquisition recorder. The pressure sensor adopts an imported titanium/silicon-sapphire sensor, offering high sensitivity and low drift.

Currently, it is mainly applied in hydrological, geothermal, engineering, and related logging fields.
