Entrelec's MTC 6 thermocouple ter-
minal block provides an interface for
connecting thermocouple wire with
virtually no loss of signal integrity. The
interface design ensures positive wire
continuity and allows selection and
inventory of one terminal block for all
thermocouple material.
The thermocouple principle is based
on the reaction of different metals to
temperature. When thermocouple
wires are terminated or connected,
the "metal balance" must be
maintained. The introduction of a
foreign material (such as copper)
results in loss of signal strength and
integrity.
When running extended or intermittent lengths of thermocouple wire, to a
measurement instrument, two solutions are available :
Universal terminal block
Other thermocouple terminal blocks are available with hardware (screws,
clamps and connecting bar) which match the thermocouple material being
used. This requires inventory of many different terminal block types.
Entrelec's MTC 6 terminal block adapts to all thermocouple material. This
"neutral" method of connection limits the introduction of foreign materials to
an insignificant level. The thermocouple wire insulation is stripped (31 mm
maximum) and the bare wires are superimposed on one another. The
thermocouple wires are in contact over their complete 31 mm length and
tightened at two points by round tip screws (see figure 2). The screws, made
of plated brass, have only a mechanical function, that of holding the wires
together with a point contact. Thus, the pressure points are not relevant in the
connection environment.
One thermocouple lead connects through one terminal block (see figure 2).
The MTC 6 requires only 6 mm of space, allowing 50 terminals per foot of rail.
Thermocouple shield wire connector bar
The MTC 6 can be field or factory equipped with a shield connector bar (see
figure 1). This bar, made of treated brass, mounts in the lower part of the
terminal block. It ensures the continuity of the thermocouple wire shield
through the terminal block or to ground with no additional spacing.

2. When thermocouple wire is of insufficient length, termination and
transmitter is required. The thermocouple signal, in millivolts (mV), is
converted to a milliampere (mA) signal (i.e. 4-20 mA) for ease of
transmission.
