1 Description of the temperature calibrator TP 18 850 E
The test instrument TP 18 850 E consists of
two single enclosures, front size 192 x 192 mm
and depth 410 mm or 510 mm. They are
connected with each other and equipped with
a portable handle.
The left enclosure contains a HT alloy block
with a bore, diameter 18 mm (28 mm) and
depth 100 mm (200 mm), which can be
reached from the top, for the reception of the
test piece. In this block the heating cartridge
and the temperature sensor for the
determination of the block temperature are
installed accessible from the bottom.
The right enclosure contains the controller for
control of the block temperature. A Solid state
relais is used for the activation of the heating
catridge.
On the front plate is the controller, a switch for
mains power and also a switch for fan. The
controller is equipped with a 2-line, 4-digit,
7-segment LED for block temperature and set
value.
On the right hand side of the instrument
combination the IEC chassis mounting plug for
the mains connection is available. Besides the
mains power cable the fuse holder is located.
