Thermoelectric temperature transducer
FSHT■ Application
By inputting thermal electromotive forces of various kinds ofthermocouples based on the JIS, the device insulates input
and output, and then converts thermal electromotive forces
into an output proportional to temperature. Up to 16 units
can be housed in an installation base.

■ Feature

Compact and high withstand voltage.
Withstand voltage between input/output/auxiliary
supply/outer case is AC2, 000V (50/60Hz) for 1 min..
Constant voltage/current output type. No need to adjust
the product if it operates within load resistance range.
A LED can confirm status of electric power applied.
Zero/span is adjustable. (±2% adjustable)
Plus (+) or minus (-) burnout can be specified.

Thermal electromotive force as an input
varies along with temperature change of
input terminal. Terminal temperature ismeasured by a RJC (compensating sensor)
and the changed portion of thermal
electromotive force casued by thistemperature change is compensated.

Compensating wire

A compensating wire compensates for thetemperature difference between thermocouple
terminals and transducer terminals.
Keep in mind that different thermocouple
needs different compensating wire.

External conducting wire resistance range

External wire resistance is the resistancevalue of a reciprocating circuit. The
reciprocating circuit consists of thermocouple,compensating wire and connecting wire
connected to a transducer. Use the productwithin an external conducting wire resistance
range less than or equal to 500Ω.
