  • Introduction
  • Specifications
QBW Pneumatic Temperature Transmitter (Thermocouple, thermal resistive, heat resistance temperature type) can be used with corresponding sensing element to measure a variety of medium temperature in industrial processes and convert temperature into 20~100kPa standard pressure signal output in proportion.
accuracy:when ambient temperature is 20 ± 5 ℃, the basic error is not more than ± 1%.
When ambient temperature exceeds 20 ± 5 ℃, temperature additional error is not more than 0.6% for every 10 ℃.
Cold-junction compensation error:K, S-type thermocouple is0.2% per 10 ℃;
E-type thermocouple is 0.75% per 10 ℃.
Anti-interference:External magnetic field interference≤400A/m,error≤±1%。
