-20~80c Temperature Instrument Integration PT100 Temperature Sensor With 4-20mA Transmitter
A temperature sensor is a device that measures temperature and converts it into an electrical signal. Widely used in industrial, commercial, and residential applications.
Opis
An RTD Temperature Transmitter (Resistance Temperature Detector or Resistance Temperature Device) is one of the most prevalent temperature sensors used in industry today. Običajno imenovan tudi PT100/PT1000, njegova posledična priljubljenost je posledica njegove natančnosti in odziva, pri temperaturah med -300 do + 600 ° C.
Kot senzor za merjenje temperature se uporablja industrijski toplotni upor. Običajno se uporablja z instrumenti, snemalniki, in elektronski regulatorji. Lahko neposredno meri ali nadzoruje tekočino, pare in plinasti mediji ter trdne snovi, v različnih proizvodnih procesih iz -200 °C do 600 °C. Temperatura površine.
V skladu z nacionalnimi predpisi, termočleni, izdelani v našem podjetju, izpolnjujejo IEC mednarodni standard stopnjevalne številke Pt100 platina toplotna odpornost, in poklicno standardno številko graduacije Cu50 toplotna odpornost bakra, dve vrsti montaže, toplotna odpornost poenotenega tipa konstrukcije.
Lastnosti:
* Uvožena originalna odpornost na platino (Pt100/Pt1000), dobra konsistenca; * High temperature measurement accuracy and reliable performance; * Two-layer package, good anti-vibration performance; * High mechanical strength and good pressure resistance. * Standard pipe thread installation
Measurement range | -200~600°C |
Index | Pt100 |
Accuracy level | Class A (±0.15°C+0.005|t|), Class B (±(0.30°C+0.005|t|) |

Protection tube material | nerjaveče jeklo 304,321,316 |
Thermal resistance wiring | two-wire wiring, three-wire wiring, four-wire wiring. |
Thermal response time | T0.5 ≤ 45S (when the temperature changes stepwise, the output of the thermal resistance changes to 50% of the change, and thetime required is called thermal response time, expressed by T0.5). |
Thermal resistance Nominal pressure | generally refers to the static external pressure, that can be withstood by the protective tube at room temperature withoutbreaking. |
The minimum insertion depth of the thermal resistance | it should be no less than 8-10 times of the outer diameter of theprotection tube (except for special products). |
Thermal resistance self-heating effect | When measuring the current 5mA through the thermal resistance, the measured resistance increment is converted into a temperature value of not more than 0.30 °C. |
Thermal resistance insulation resistance | The test voltage of the normal temperature insulation resistance can be any valueof DC 10~100V, the ambient temperature is in the range of 15~35°C, in relativna vlažnost ne sme biti večja od 80%. Vrednost izolacijskega upora pri sobni temperaturi ne sme biti nižja od 100 MΩ. |
