Product profile  :  TDJ-NM Non-magnetic Theodolite

 

Non-magnetic theodolite is special equipment designed by Bofei for geomagnetism testing field . Over the past 20 years, the magnetic theodolite products provided by Bofei have been highly regarded . Bofei has TDJ6-NM, TDJ6E-NM and TDJ2E-NM non-magnetic theodolite products, and three geomagnetic theodolites combining these three products and flux-gate magnetometer.

Characteristics

Bofei Non-magnetic Theodolite is a key part of the geomagnetic theodolite, whose biggest difference with ordinary optical theodolite is its non-magnetic property. It is actually highly weak magnetism. It is required to be weak enough to not affect the observation accuracy of D and I. Because of these special requirements, special design is required to design specially in instrument structure, material selection, processing and manufacturing and magnetic inspection. Selection, processing and manufacturing and magnetic inspection. Combinging with many years of experience in designing and manufacturing optical theodolite, Bofei has developed and produced the non-magnetic theodolite, introduced test equipment with the world’s advanced level in order to meet the strict demand for non-magnetic , and developed a set of specialized magnetic test method.

Currently Bofei Non-magnetic Theodolite has reached world leading level in observation accuracy and non-magnetic property.

 In addition to performance indicators of level J6 and J2 optical theodolite, magnetic cleanness of TDJ6 / TDJ6E-NM and TDJ2E-NM Non-magnetic Theodolite has also maximized the magnetic influence on the overall unit to be no more than 1nT.

Bofei can customize sensor connector connecting the flux-gate sensor according to customer’s drawing requirements.

Bofei geomagnetic theodolite, as one of the highest- precision instruments for D and I observation currently in the world , is a geomagnetic absolute observation instrument intergting the optical, mechanical and electrical factors together, which has the world’s advanced level. As it can accurately determine magnetic declination D and geomagnetic inclination I, it can be used in geomagnetic station and in the field . The instrument is stable, easy to operate, of great use, easy to carry and other features, This instrument can be used in geomagnetic station, and it is also suitable for outdoor mobile geomagnetic observation. At the same time , it can be used as common theodolite, for example, it can be used for observation of azimuth, latitude and longitude, ect, which has changed the tradition practice that needed another common thedolite for geomagnetic observation.

With the above features, DI theodolite can be widely used in geomagnetic research, data collection , mapping ,defense, earthquake prediction, oil and various mineral exploration, aviation and navigation orientation, and many other fields, Geomagnetic observation can be implemented on a fixed station or measuring point in the field.
