Absolute pressure transmitter ASP2000B

analogHARTfor gas

The pressure transmitter is mainly applied to measure pressure, negative pressure, absolute pressure and other parameters of gas, liquid or vapor, then to convert these parameters into 4~20mA DC. It can connect with HART manipulator to make self-diagnosis, reset measuring range and set zero automatically. The pressure transmitter δ cell receives measured pressure from one side, meanwhile, connects with the air to detect pressure or negative pressure. Zero migration volume Maximum zero positive migration volume:difference between migration volume upper range and measuring range No negative migration volume Measuring range Lower range limit:-100%URL (≥-0.1MPa)～+100%URL-Span Upper range limit:-100%URL+Span (≥-0.1MPa+Span)～+100%URL Measuring range and zero adjustment HART manipulator, local button, HART protocol supported by communication software. Response time When the electrical damping of the transmitter is turned off, the response time of the step input applied to the transmitter from 10% to 90% of the output range is less than or equal to 0.4s. Measuring object: liquid, vapor and gas Accuracy: 0.1% F.S Range ratio: 100:1 Insulation resistance: >100MΩ (100VDC) Damping value: 0.1～16s (Optional) Temperature affecting value: 0.1%F.S/10℃ Output signal: 4～20mA(Max 22mA,Min 3.8mA) Communication interface: HART Intrinsic safety: EX ia IIC T6
