the case of long RTD‘s
Mineral-Insulated Metal-Sheathed Resistance Thermometer
Detectors (MIMS RTD’s) supplement the
Mineral-Insulated Metal-Sheathed Thermocoup les
(MIMS TC´s), which are tested and approved over
many years. MIMS RTD´s can be applied for temperatures
from -100 °C up to +550 °C. They combine
the advantages of the MIMS RTD´s with tho se
of the bendable mineral-insulated metal-shea thed
thermocouples.
Important advantages of the MIMS RTD´s:
· bendable with small radius
· suitable for high pressure and vacuum
· two-, three- or four-wire circuits are possible
· easy packing and shipment even in the case
of long RTD´s
As supply wires mineral-insulated metal-sheathed
cables are used. The supply wires are embedded in a
MgO compact insulation and surrounded by a metal
sheath of stainless steel. The compact in sulation fixes
the wires completely so that they can not be damaged
neither by vibration nor by strong bending. Short
circuits between the wires or between them and the
metal sheath are impos sible.
The minimum bending radius depends on the out side
diameter of the MIMS cable. About 5 to7 of times the
outer diameter is a practicable standard value.
The measuring resistor itself complies with the requirements
of the DIN EN 60 751:2009 standard.
If in special cases, for example in the case of gre at
lengths, the inner conductor resistance increa ses
more than usual, the resistance is shown on the
identification plate.
The temperature sensitive length of the RTD is typically
35 mm. Different lengths can be supplied
upon request.
