Wild T2 Theodolite The Wild T2 is the classic opto-mechanical theodolite. Hardly another surveying instrument has so profoundly influenced surveying on every continent. There is also a wide range of objective accessories, such as supplementary front lenses and parallel-plate micrometers. The instrument has a partly digital circle display to 1”, an optical plummet in the tribrach. A wide range of accessories is available.
Circle readings made easy. The T2 is available with circles divided into 360 degrees. The scale circles are shown in the reading microscope next to the telescope eyepiece. The user chooses the vertical or horizontal circle by setting the selector knob in the required position.
The two circles can be readily distinguished: the horizontal scale is yellow, the vertical is white. Specifications: Maginification, with standard eyepiece: 30x Clear objective aperture: 1.6 inch Field of view at 1000 ft: 29 feet Shortest focusing distance: 7.2 feet Spherical level: 8' Plate level, standard: 20' Automatic veritcal index: Setting accuracy: ± 0.3' Working range: ± 5' Smallest interval of optical micrometer: 1' Mean height of tilting axis: 9.328 inch Please contact us for additional information & pricing (708)482-8888 or sales@karaco.com.
Figure 1: 1962 Wild Heerbrugg T2 theodolite This Wild Heerbrugg T2 universal instrument was part of a large donation to my collection together with a theodolite, a theodolite, a level, a level, a level, a, and various accessories. Provenance The above mentioned group of instruments once was part of the set of instruments used by the field organisation TGTW of the Survey Department (Meetkundige Dienst, 'MD' in short) of Rijkswaterstaat (part of the Dutch Ministry of Infrastructure and the Environment, responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands). The department was closed in the early 2000s and in 2008 the instruments were donated to my collection. Development The Wild T2 was first produced in 1926. The in my collection was the third modification of the first model. The instrument shown here was the third model T2 produced, which was produced between 1956 and 1968, and dates from 1962. Two years later it would be followed by the in my collection.
Accuracy This Wild T2 universal instrument is equipped with glass circles (90mm diameter horizontal and 70mm diameter vertical) and a optical reading mechanism. The T2 does not have a compensator for the vertical index, a coincidence vial is used instead (see ). With 70mm diameter the vertical circle of this third model T2 is substantially larger than that of the, while the horizontal circle remained the same. This T2 has centesimal circles divided down to 20c (0.20gon) intervals, can be read using a micrometer directly to 2cc and estimated to at least 1cc (see and ). The circles are illuminated by two distinctive rotating mirrors; one directly on the secondary axis and one at the base of the instrument (see and ). Figure 2: The Wild Heerbrugg T2 from the other side.
Alternatively the circles can be illuminated by electric lights, but sadly enough the instrument came without them. Production The were produced in 1926. Up to 1970 a total of 38,800 were made and many more thereafter.
Here in the Netherlands the T2 has been the most popular instrument among surveyors for many decades and probably every surveyor educated here in the second half of the 20 th century has worked with it. According to the Ahrend Prijscourant 22 of 1962 a 'T2 in metalen stolp, met optisch lood. Elektrische verlichting zonder statief, 400g.' ('T2 in metal cover, with optical plumb.
Electrical lighting without tripod, 400g') would have cost fl.3,630. The instrument This Wild T2 came complete with its steel container and lens cap.
It is centesimally divided. The telescope has a magnification power of 30 times. The inverted field of view shows four stadia hairs with a multiplication factor of 100 (see ). Centring can be done using an optical plummet, which has a normal cross-hairs for the purpose (see ). Dov ss simens workbook pdf. Externally there are only two differences with the; the peep sight on the telescope (see, it is no longer featured on the later model) and the sliding (instead of turning) locking mechanism of the tribrach (see and ). Internally the presentation of the coincidence reading method of the circles and the interval of the micrometer differ from the later model (see and ). Notes []: See the at the.
