BDR type rotary angle model
Long service life and wear-free measurement accuracy for industrial applications such as machine and plant engineering as well as marine components and marine engineering utilities. The housing and temperature scale rotate 360 ° for a reading from any angle on our BDR thermometer.
Nominal dimensions 110, 150 or 200 mm, aluminum, V-shaped, fully polished, gold anodized (or silver on request). Reading scale numbers printed on the right side. Print in black for easy readability. Straight types adjustable to any desired viewing position and locked with a brass nut, wrench size 22. The angular thermometers (90 degrees) have a grooved adapter piece with locking screws. Advantage: when mounting the thermometer, it is not necessary to turn the housing.
Glass inserts (capillaries)
Capillary tube in solid glass, bar-shaped, prismatic (optical enlargement of the column, except for high temperature types), diameter approx. 8 mm, oval opening, with yellow background for mercury and white background for blue fluid column. The scale is deeply burnt in black, which gives it absolute resistance. The main graduations, which correspond to the impression on the case, are particularly well defined.
In the standard version from -30 to 250 ° C blue thermometric fluid ("Fü"); for display ranges starting at 0 ... 300 ° C, only mercury filling is technically possible.
Standard version in brass for temperatures up to 300 ° C, in steel for temperatures max. Temperature. On request, high resistance brass or CuNiFe alloy suitable for seawater. Stainless steel for aggressive fluids. The diameter of the type “B” dip tube is 10 mm; the wall thickness 1 mm.
