Smart Pressure Transmitter
Key Specifications/Special Features:
I Product introduction
The pressure transmitter is mainly applied to measure pressure, negative pressure, absolute pressure and other technical data of gas, liquid or vapor, then converts these data into 4~20mA DC signal output. It can connect with HART manipulator to promote self-diagnosis, reset measuring range and auto-zero functions. One side of pressure transmitter's δ cell receives measured pressure,
meanwhile, the other side connects with the air to detect pressure or negative pressure
Applications
Measuring pressure of pipeline and storage tank in petroleum, petrochemical and chemical industry.
Meeting high stability and precision requirements in electric power, city gas and other utilities.
Realizing stable measurement under temperature & humidity strictly controlled conditions in iron, steel, nonferrous metal and ceramic fields.
Using in the fields of pulp and paper where the resistance of chemical liquid and corrosion liquid is required.
Realizing stable measurement under temperature & humidity strictly controlled condition in machinery and ship building fields.
II Performance Parameters
Zero elevation and suppression:
The maximum zero elevation is the difference between upper range limit and span
The maximum zero suppression no more than the atmospheric pressure
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, communication software supported by HART protocol
Response time
When the electrical damping of the transmitter turns off, the response time of the step input applied to the transmitter from 10% to 90% of the output range is less or equal to 0.4s.
