THERMASGARD ®
Calibratable temperature measuring transducer THERMASGARD
measuring ranges and continuous output, with connecting head made from aluminium (optionally
with cable gland or M12 connector according to DIN EN 61076-2-101) and straight protective tube.
A basic unit in four variants through combination with accessories, eg, for robust applications with
a separate immersion sleeve made from stainless steel. The duct sensor is used to detect tempera-
tures in liquid or gaseous media. It is used in pipes, heating engineering, storage systems, compact
district heating stations, warm and cold water systems, oil and lubrication cycle systems, mechanical,
apparatus and plant engineering and throughout the industrial sector.
calibrated; an environmental precision adjustment by an expert is possible.
