-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.
설명
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, 그에 따른 인기는 정확성과 응답성 때문입니다., 사이의 온도에서 -300 에게 + 600 ° C.
Industrial thermal resistance is used as a temperature measuring sensor. 일반적으로 악기와 함께 사용됩니다., 레코더, 및 전자 레귤레이터. 액체를 직접 측정하거나 제어할 수 있습니다., 증기 및 기체 매체와 고체, 다양한 생산 과정에서 -200 °C ~ 600 ℃. The temperature of the surface.
According to the national regulations, 당사에서 제작한 열전대, 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.
특징:
* 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
