●Operating temperature range of thermal resistance: Pt: -200-＋650℃; Cu: -25-＋120℃. Ni also can be manufactured.
●Open of current output: even if the current output terminal is used in a state of regular open, there is no problem.
Also, a voltage of approx. 15V occurs on the output terminal.
●DC110V power source: Type code is RHTT2-83A.

RESISTANCE TEMPERATURE TRANSDUCER●Built-in linearizer
The resistance value of a measurement temperature resistance is not proportional to temperature.
The linearizer converts a measurement temperature resistance into an output proportional to temperature.
●Built-in burnout
The device detects disconnection of a measurement temperature resistance and does scale-out of output to positive(+) side. Scale-out to negative side is also manufacturable if specified.
●Specified current
Specified current is a current flowing into a thermal resistance. Change of resistance value can be measured byvoltage drop caused by the specified current. In the case of Pt, though standard specified current is 2mA, 5mA is also
manufacturable if specified.
●Built-in external conducting wire resistance compensating circuit
External conducting wire resistance is the resistance value of conducting wires excluding the resistance value ofelement S. As the influence of external conducting wire resistance, it does compensate when resistance values of all
conducting wires are equivalent, but it becomes an error when resistance values of all conducting wires are different.
Generally, taking into consideration the variousness of conducting wires, use the product under ranges listed in thetable below.
