PT1502 Transmitter for Wellkonix Differential Pressure Transmitter pressure, liquid level, and flow rate may all be precisely measured with high-performance single crystal silicon differential pressure technology. and sends off a 4–20 mA proportionate output signal. Full detection range: 1kPa–3MPa. ± 0.05% / 10MPa static pressure inaccuracy in a high-performance static pressure test design
Principle of Differential Pressure transmitter
The main unit functions as follows and has a sensor and process connection. The process medium is delivered to the measurable silicon pressure chip through a flexible, corrosion-resistant isolation diaphragm, and fill fluid pressure is applied. A chip termination that is either linked to vacuum (for an absolute pressure measurement) or the atmosphere (for a gauge pressure measurement). The output voltage of the detecting system varies as a result of the silicon chip of the sensor changing in resistance as the measured pressure passes through the measuring diaphragm and the filling liquid. The change in pressure is proportionate to this output voltage. The output is converted by the amplifier and adaptor unit into a standardized signal output.
