Smart Pressure Transmitter 4-20mA HART Differential Pressure Transmitter China
Description of Smart Pressure Transmitter 4-20mA HART Differential Pressure Transmitter China
The Smart Pressure Transmitter 4-20mA HART Differential Pressure
Transmitter will cause changing of capacitance value, analog signal
convert to digital signal via AD and then being transfered to
microprocessor, processed by microprocessor then convertted to
4～20mA analog electricity signal via DA.
The differential pressure transmitter is suitable to measure
liquid, gas, or steam flow as well as liquid level, density and
pressure. Outputs a 4~20mADC signal corresponding to the measured
differential pressure. Its highly accurate and stable sensor can
also measure the static pressure which can be shown on the integral
indicator or remotely monitored via HART communications. Other key
features include quick response, remote set-up using
communications, self-diagnostics and optional status output for
pressure high/low alarm.
