Embodiment
A kind of resistance thermometer clement analogue means, this device are a thermal resistance resistance generator, are that standard is carried out segmentation with the resistance wire of thermal resistance resistance generator by resistance thermometer clement temperature corresponding resistance of institute and the pairing resistance difference of temperature difference; Lead-out terminal inserts the two ends of institute's sub-resistance section by adjusting knob; Its resistance value adjusting is degree centigrade being unit.
During concrete operations, utilize the principle of resistance box that the actual temperature that will export is divided into hundred, ten, individual position, its actual output temperature is every temperature value summation, degree centigrade being unit.The adjusting of every temperature relies on knob to realize; Rely on ten resistance wires, every resistance wire during with-100 ~-91 ℃ the pairing resistance value of temperature element (TE) Pt100 be basic resistance value, the basic pairing resistance of resistance value is basic resistance, ten resistance wires are difference with 10 degrees centigrade of pairing resistance value differences of the every rising of basic resistance value respectively, utilize difference that resistance wire is carried out segmentation, every section resistance wire is a difference resistance.The a end of ten basic resistance of resistance wire is ten gear points of a cut-in temperature position adjusting knob respectively, temperature position adjusting knob can by rotation make its public point respectively with ten gear point conductings, its public point and simulation box lead-out terminal A link, make simulation box lead-out terminal B, the C parallel connection, the public point of ten adjusting knobs of cut-in temperature, ten gear points of ten adjusting knobs of temperature insert on the other end of the resistive segments between these hundred adjusting knob gear designation area of resistance wire by hundred adjusting knobs respectively, this resistive segments is lead-out terminal B, the b end of C and difference resistance links, the a end of difference resistance is connected with the b end of the difference resistance that basic resistance b end or basic resistance b end link to each other, perhaps lead-out terminal B, C directly links with basic resistance b end.According to the difference of the temperature value of being adjusted, corresponding to different difference resistance terminal.The resistance of its output is the resistance sum between lead-out terminal A, the B.Finally reach the purpose of simulating resistance and temperature element under the different temperatures under the normal temperature.
A, B, C are external terminal among Fig. 1, and R000 ~ 009 is ten basic resistance basic resistances of corresponding-100 ~-91 ℃ respectively, and R010 ~ 599 are resistance-(100 ℃ the resistances) of corresponding R010=-90 ℃ of difference resistance difference; The resistance of R011=-89 ℃ resistance-99 ℃; The resistance of R012=-88 ℃ resistance-98 ℃ R019=-81 ℃ resistance--91 ℃ resistance.In like manner, the resistance of R500=400 ℃ resistance-390 ℃; The resistance of R501=401 ℃ resistance-391 ℃; The resistance of R502=402 ℃ resistance-392 ℃ The resistance of R599=499 ℃ resistance-489 ℃.K1 is a position adjusting knob; K2 is ten adjusting knobs; K3 is hundred adjusting knobs, utilizes the principle of variable rheostat then, and two end points that change its resistance wire that inserts by adjusting knob reach the purpose of regulating resistance.
In the DCS system implementation process, when on-site cable or resistance thermometer clement do not install, detect at the scene, the thermal resistance input template is detected, add the resistance signal to detect toward template for carrying out the loop.Can adopt the utility model.
