Long service and measurement accuracy without wear for industrial applications such as machine and plant engineering, pipeline construction as well as power plants. This version with union nut is ideal for the use with thermometer protection tubes.
Nominal size 200 mm, aluminum, V-shaped, completely polished, gold-coloured anodized (or silver-coloured upon request). Numerals of reading scale printed on the right side. Printing black-colored for easy readability. Straight types adjustable to any desired viewing position and locked by brass nut, wrench size 22. Angle thermometers (90 degrees) have a grooved adapter piece with locking screw. Advantage: When mounting the thermometer, it is not necessary to turn the casing.
Glass inserts (Capillaries)
Capillary tube of solid glass, bar-shaped, prismatic (optic 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. Scale is deeply burnt in black, thus being absolutely resistant. The main graduations, which correspond with the printing on the casing, are especially clearly outlined.
In the standard version from -30 to 250 °C blue thermometric fluid ("Fü"); for temperatures above 250 °C only mercury* is possible (short designation "Hg").
Standard version made from brass for temperatures up to 300 °C, from steel for higher max. temperature. On request, highstrength brass or CuNiFe alloy suitable for sea water. Stainless steel for aggressive media. The diameter of the type “Da” immersion tube is 10 mm; the wall thickness 1 mm.
Scale intervals and error limits
SIKA thermometers fulfil the requirements of DIN 16195 „Requirements and testing of industrial glass thermometers“. Scale intervals and error limits are defined in relation to the casing size and the display range.
