Thermometers with condensation barrier


Product description

Possible areas of application

Thermometers with condensation barrier

When using normal industrial thermometers in cold applications, rapid cooling of the thermometer housing occurs due to the good thermal conductivity of the immersion tube and aluminium housing. In the event of high air humidity, condensation may form on the housing. This effect can be avoided by using a thermometer with a condensation barrier.



Nominal size 150 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. 6 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.

Thermometric liquid
In the standard version from -30 to 50 °C blue thermometric fluid (“Fü”).

Immersion tube
Standard version made from brass. On request, stainless steel. The diameter of the type “B” 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.

Condensation barrier
The length of the condensation barrier is 50 mm. As a secondary effect, this distance permits the bridging of thick tube insulation between the immersion tube nipple and thermometer housing.

Sealing sleeve
Thermometer with sealing sleeve as a standard - reduces the penetration of moisture into the immersion tube (outdoor mounting, low temperature applications)
