Calibratable temperature measuring transducer
THERMASGARD
®
TM 54
with eight switchable
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. The sensor is factory-
calibrated; an environmental precision adjustment by an expert is possible.
