125μs/m~555μs/m Sonic & Temperture & Inclinometer Probe accuracy
5μs/m with pt100 sensor
Description
The Sonic probe used extensively in the groundwater, mining, and
geotechnical industries. Sonic logs are widely employed, often in
combination with other logs, to provide porosity, permeability, and
geo-mechanical properties. This probe is ideal for cased-hole and
open hole applications, such as fracture identification and cement
bond logging.
The Temperature probe provides borehole temperature measurements.
The borehole temperature measurement is helpful to detect anomalies
caused by events such as fluid flow into the borehole.
The Inclinometer is suitable for non-magnetic or weak magnetic area
using the drilling direction of testing instruments. Can be used in
geology, oil, coal and other industries in the process of drilling,
testing the quality of the hole. In water conservancy construction,
highway, railway, bridge, tunnel, etc can also be applied in
drilling engineering.
The instrument adopts the advanced modern technology of sensor and
the digital processing technology, complete in remote measuring way
zenithal Angle and azimuth Angle measurement. Has a high accuracy
of measurement, the instrument is simple and needs no maintenance,
high reliability, and other significant characteristics of wide
application field.
Operating Conditions:Uncased；Borehole Fluid:Water or Mud.
Features & Benefits
1. Implement a high energy source wave generated by a
ceramic-piezoelectric transducer.
2. Versatile, ubiquitous probe which functions with a wide range of
applications and borehole conditions.
3. The sensor adopts Pt100 platinum resistance of a small time
constant and can quickly identify temperature changes in the
stratum.
