HT3351 Differential Pressure TransmitterIntroduction:
HT3351 Capacitive Flange Differential Pressure Transmitter
Transmitter has the optional HART module. After the transmitter is
added the HART module, it has HART communication capacity, with the
conventional operation being controlled with the general manual
operator. The special communication equipment and software provided
by our company can operate the marking and temperature
supplementation actions.
HT3351 series digitalized Intelligent Pressure/ Differential
Pressure Transmitter can be widely sued in the sectors such as
petroleum,
chemical, iron & steel, power supply, light industry and
environmental protection, capable of realizing the measurement of
various pressures,
differential pressures, flows and fluids, adaptable for all kinds
of harsh and hazardous environment and corrosive agents.
Product Features:
1. The transmitter features a stainless steel structural design,
making it compact and easy to install
2. It undergoes strict temperature compensation and aging
screening, ensuring stable and reliable performances
3. The electrical interface can be selected as a plug-in or direct
wiring option.
Applications:
1. Suitable for measuring differential pressure of various gases or
liquids in pipelines of industries such as petroleum, chemical,
power, and hydrology.
2. Applied in industrial on-site processes such as petroleum,
chemica,metallurgy, power generation, and hydrology
3. Pressure measurement for pipelines and furnace chambers
Working Principle:
As indicated in the working principle, the outside pressure or
differential pressure will cause some change in the sensor
capacitance value. Through the digital signal conversion, it will
change into the frequency signal, which is sent to the
microprocessor. After the
calculation by microprocessor, a current control signal will be
output to the current control circuit, converted into analogue
4-20mA current
output. Meanwhile, the microprocessor is responsible for the
interactive and other actions (display and setting). The
communication port used for digital communication needs the special
port of our company. HART module will realize the transmitter HART
communication.
Measurement Ways:
Fluid Level Measurement:
In the measurement of fluid flow, the pressure taps should be
breached on the side of the process conduit to avoid the sediment
of dregs. Meanwhile, the transmitter should be mounted beside or
under the pressure taps, to prevent the air bubbles from being
discharged into the process conduit.
