THERMOELECTRIC TEMPERATURE TRANSDUCER
HTT2-82A/ HTT2-83A (DC110V power source)■UseWith thermal electromotive force of various thermocouples according
to JIS as input, convert temperature with insulation into DC signal inproportion to temperature with insulation.

■Features
1. Withstand voltage 2, 000V AC (between input/output/auxiliary
supply/earth).
2. Impulse withstand voltage 5kV 1.2/50µs (electric circuit/earth),
positive/ negative polarity 3 times each is guaranteed.
3. With output line surge protection (2, 000A, ±8/20µs), can transmit
an output directly to a distant place.

§ BOX TRANSDUCER §SENSOR TRANSDUCER
THERMOELECTRIC TEMPERATURE TRANSDUCER●Built-in linearizer
Thermal electromotive force of a thermocouple is not proportional to temperature.
The linearizer converts thermal electromotive force into an output proportional to temperature.
●Built-in burnout
The device detects disconnection of a thermocouple and does scale-out of output to positive (+) side.
Scale-out to negative side is also manufacturable if specified.
●Built-in cold junction compensation
In principle, a thermocouple generates a thermal electromotive force equivalent to V(T1℃) −V(T2℃) as Vin.
Compensating sensor compensates a thermal electromotive force equivalent to T2℃.

●Compensating wire
A compensating wire compensates temperature difference between thermocouple terminals and transducer
terminals. Because color (material) of compensating wire varies according to thermocouple type, choose acompensating wire in accordance with thermocouple. Match positive and negative polarities when connecting.
●External resistance range
An External resistance value is the resistance value of a reciprocating circuit which consists of thermocouple
connected to the transducer, compensating wire, connecting wires and so on.
Use the product within a reciprocal circuit resistance less than or equal to 25Ω.
