Long-life, precise temperature measurement without wear, for industrial applications, for example in machine and plant construction, as well as for ship components and supply technology in shipbuilding.
In the original SIKA thermometer type BDR, the casing with temperature scale can be axially rotated by 360° and thus adjusted so that it can be read in any viewing direction.
» Thermometer casing axially rotatable by 360°. Adjustable for reading in any viewing direction
» No ageing due to no moving parts and no mechanical wear
» Lifetime warranty (except for glass breakage and improper installation)
» Completely without electrical auxiliary energy
» Available as type 272, 292 and 175
CASING
Nominal size 110 mm, 150 mm or 200 mm. Aluminium, V-shaped, smoothly polished on all sides, anodised in brass colour, numbers of the display range printed in black on the right-hand side of the scale under the anodised layer.
GLASS INSERT (CAPILLARY)
Circular capillary in rod form made of solid glass, approx. 8 mm Ø, as well as white background with blue liquid filling and yellow background with mercury.
THERMOMETRIC FILLING
In standard version from -30 to 250 °C blue thermometric liquid ("Fü"); for display ranges from 0...300 °C only mercury filling* (abbreviation "Hg") is technically possible and only for nominal sizes 150 mm and 200 mm.
IMMERSION TUBE
Made of brass as a standard for temperatures up to 300 °C, beyond that made of steel. On request special brass or CuNiFe alloy suitable for sea water. For aggressive media made of stainless steel. The diameter of the immersion tube types "B" and "Da" is Ø 10 mm; wall thickness 1 mm.
