§Small-sized plug-in transducer§
1 output type

Resistance temperature transducer
FSRH■ Application
By inputting resistance value of a 3-wire thermal resistancebased on the JIS, the device insulates input and output, andthen converts thermal electromotive forces into an output
proportional to temperature. Up to 16 units can be housed in
an installation base.

Specified current

Specified current is a current flowing into a thermalresistance. Change of resistance value can bemeasured by voltage drop caused by the specifiedcurrent. Standard specified current is 2mA.

External conducting wire resistance range

External conducting wire resistance is the conducting
wire resistance value which is the result of subtracting
the resistance value of objective resistance element. As
an influence of external conducting wire resistance, it
compensates when resistance values of all conducting
wires are equivalent, but it becomes error if resistancevalues of all conducting wires are different. Taking thevariousness of conducting wires into consideration, use
it in a range less than or equal to 50 Ω per 1 line.
