SWP-T51 series differential pressure transmitter using the world's advanced technology development and manufacturing of the superiority of the new differential pressure transmitter can be used as a completely sealed δ room sensor, no mechanical moving parts, thus increasing reliability. Differential pressure transmitter can accurately measure low gauge pressure, vacuum, liquid level, specific gravity and flow. Widely used in petroleum, chemical, textile, electricity, food, paper, pharmaceutical and other industries. Technical features high accuracy, good stability wire miniaturized, lightweight, strong vibration range, zero external continuously adjustable no mechanical moving parts, reliable, and easy way to safeguard the full range overload protection feature unified structure, components interaction In other strong proof structure, works around the clock to use low pressure were measured media into the high-pressure chamber measuring element, acting on the diaphragm, the two diaphragm liquid filled pressure signal is transmitted to the central measuring diaphragm, center of a measuring diaphragm is tensioned elastic element, an effect corresponding to the measuring diaphragm produces a pressure differential of deformation, displacement and deformation is proportional to the pressure difference in the measured pressure difference on both sides of the center on the displacement of the capacitor electrode plate produce a corresponding change in capacitance, the electronic circuit detects this change in capacitance and amplified and converted into a corresponding current signal. If the low-pressure chamber through the atmosphere, the high-pressure chamber connected to the measured medium can be measured at this time relative pressure medium. Similarly, if the low pressure vacuum chamber, hyperbaric chamber measured media then you can take the measured absolute pressure medium.
