§ PLUG-IN TRANSDUCER § 1 OUTPUT TYPESENSOR TRANSDUCER

THERMOELECTRIC TEMPERATURE TRANSDUCER
HTP1 -■ Use
By inputting thermal electromotive forces of various kinds ofthermocouples based on the JIS, the device insulates and converts
thermal electromotive force into an output proportional to temperature.

■ Features
1. Constant voltage/current output
2. Withstand voltage between input, output, auxiliary supply and outercase (earth) is AC1, 500V (50/60Hz), complete insulation for 1 minute.
3. Impulse withstands voltage 5kV, 1.2/50μs (between electric circuit andouter case), and positive/negative polarity 3 times each is guaranteed.
4. With output line surge protection (2,000A, 8/20μs, positive/negativepolarity), can transmit an output directly to a distant place.

§ PLUG-IN TRANSDUCER § 1 OUTPUT TYPE
●Built-in linearizer
Thermal electromotive force of a thermocouple is notproportional to temperature. Thermal electromotiveforce is converted into an output proportional totemperature by a linearizer.
●Built-in burnout
Detects disconnection of thermocouple and does
scale-out of output to positive (+) side.
Scale-out to negative side is also manufacturable if
specified.
●Cold junction compensation
In principle, a thermocouple generates a thermal
electromotive force equivalent to V (T1℃) －V (T2℃)
as the Vin.
A sensor for compensation compensates for a thermal
electromotive force equivalent to V (T2℃)
In the case of cold junction compensation, the sensor
for compensation is connected to terminal part (5・6),
and it compensates for temperature of terminal (5・6)
as temperature of input terminal (3・4).

SENSOR TRANSDUCER●External resistance range
External resistance range is the resistance value of areciprocating circuit. The reciprocating circuit consistsof thermocouple, compensating wire and connecting
wire connected to a transducer. Use the product within
an external resistance range less than or equal to 25Ω.
●Input wiring
Because a signal of input wiring is very weak, try tomake the wirings away from noise sources such as anelectrical power line, a precipitous voltage or a linewith current fluctuation.

A compensating wire compensates for the temperature
difference between thermocouple terminals andtransducer terminals. Because color (material) ofcompensating wire varies according to thermocouple
type, choose a compensating wire compatible withthermocouple. Match positive/negative polarities whenconnecting.
