Features
Jacketed resistance thermometers combine the
accuracy of PT sensors with the advantages of
well proven jacketed thermocouples. The probe is
suitable for temperature range between -70... +500
°C and is the most optimum design with respect to
highest possible accuracy together with a robust
protected construction.
Mineral insulated jacketed cable is used as the
lead wire to sensor element. The lead wires are
embedded in a compact insulation of MgO and
enclosed in a metal jacket of high grade alloy non
rusting steel (material No. .: 1.4541 or INCONEL).
The compact insulation completely consolidates
the wire so that no damage can occur either due to
vibration or by bending pressure. The minimum
bending radius is around 15 mm.
The platinum sensor is placed at the tip of the
assembly in a protection sleeve which is hermeti-
cally tight sealed with the jacket lead wire. There-
fore, the model is very well suitable for critical
applications, for example, in the cryogenics. The
temperature sensitive length at the tip is 35 mm.
The protection sleeve is filled with MgO powder,
through which it has an extremely fast conversa-
tion behaviour with optimum protection to the
sensor, for example in case of vibration.
The mounting in the installation is either done
through the 1/8 “ threads or 6mm clamping set.
The connection to M12 plug connector is through a
four wire system. The plug connector has a protec-
tion type IP67. The scope of supply is without
connection cable; if required, please separately
include with the order!
