4-20Ma smart pt100 temperaturgivare med rtd sensor temperaturgivare
Beskrivning
An RTD Temperature Transmitter (Resistance Temperature Detector or Resistance Temperature Device) is one of the most prevalent temperature sensors used in industry today. Also commonly referred to as PT100/PT1000, its resulting popularity is due to its accuracy and repsonse, at temperatures between -300 to + 600 ° C.
Industrial thermal resistance is used as a temperature measuring sensor. It is usually used with instruments, recorders, and electronic regulators. It can directly measure or control liquid, vapor and gaseous media and solids, in various production processes from -200 °C to 600 °C. The temperature of the surface.
According to the national regulations, our company’s fabricated thermocouples, meet the IEC international standard graduation number Pt100 platinum thermal resistance, and the professional standard graduation number Cu50 copper thermal resistance, two types of assembly, unified design type thermal resistance.
Funktioner:
* Imported original platinum resistance (Pt100/Pt1000), good consistency; * 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
