Possible areas of application
Long service and measurement accuracy without wear for large-scale heating systems, district heating, and cold-water circulation systems in air conditioning. OEM version, only for volume quantities.
Nominal size 110, 150 or 200 mm, plastic casing, top section made from polyamide PA6, black-coloured. The numbers of the display range are printed on the right side and are long-lasting. Connection of casing and immersion tube through grooved adapter piece and locking screw. Advantage: When mounting the thermometer, it is not necessary to turn the casing. Max. ambient temperature 160 °C.
Glass inserts (Capillaries)
Capillary tube of solid glass, bar-shaped, prismatic, diameter approx. 6 to 8 mm, with 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 up to 200 °C blue wetting fluid („Fü“).
Standard version made from brass, type B with connection thread G½. The diameter of this immersion tube is 10 mm, with a wall thickness of 1 mm. Stainless steel available as an option.
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. For example, a 291 HBZ thermometer, typical for heating applications, with a display range of 0 to 120 °C, has a scale interval of 2 °C and an error limit of 1 °C.
