Process Engineering Section – Instrumentation and Automation Technology Forum – Daily Question – Questions 08–27: True or False? The original measurement range of the 1151GP pressure transmitter was 0–100 KPa; after a 100% zero shift, the instrument’s measurement range became: 100–200 KPa. The gauge range is 100 KPa. When a pressure of 160 KPa is applied, the gauge outputs 12 mA. Reference answer: Incorrect
×, input 150kPa, output 12mA
