Process Engineering Division – Instrumentation and Automation Section – Daily Topics – Topic No. 2020-12-03: Discussion topic: The measurement range of the 315 and 1151GP pressure transmitters was originally 0–100 KPa; now the zero point has shifted by 100%. Then: 2. What is the range of the instrument? (Additional points will be given for a correct calculation process or detailed explanation)
The gauge range is 100KPA~200KPA
The overall pressure increases by 100 KPA, so the gauge range is 100 KPA~200 KPA
The overall pressure is increased by 100KPA, so the gauge range is 100KPA~200KPA
The range of the gauge is 100 KPa. Analysis: The original measurement range of the gauge was 0–100 KPa; now that the zero point has shifted by 100%, the gauge’s range is 200 – 100 = 100 KPa.
Everyone, pay attention to the question wording – it refers to the range, not the scope. The range of the gauge is 100 KPa. The range is of course 100~200 KPa. Answer: The original measurement range of the gauge is 0–100 KPa. With a zero shift of 100%, the gauge’s range becomes 200 – 100 = 100 KPa.
