The pressure transmitter is mainly applied to measure pressure, negative pressure, absolute pressure and other parameters of gas, liquid or vapor, then to converts these parameters 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 transmitters δ cell receives measured absolute pressure signal, meanwhile, the other side is sealed to be base cell to measure absolute pressure of exhaust system, distillation tower, evaporator and crystallizer ect.
Measuring absolute 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 shift volume
Maximum positive shift volume: difference between shift volume upper range and measuring range.
No negative shift volume.
Lower range limit: 0%URL~+100%URL-Span
Upper range limit: Span~+100%URL
Measuring range and zero adjustment
HART manipulator, local button, communication software supported by HART protocol.
