Results As the name suggests differential pressure transmitter measures the pressure difference between the differential pressure transmitter that △ P = ρg △ h. And since the tank is often cylindrical, its cross-sectional area of ??a circle S is constant, then the smart differential pressure transmitter, gravity G = △ P · S = ρg △ h · S, S constant, G and △ P proportional relationship. As long as the accurate detection of △ P value, and inversely proportional to the differential pressure transmitter height △ h imports, changes in temperature, although the oil volume expansion or reduction, increase or decrease the actual level, the detected pressure is always It remains the same. If you need to display the actual level, temperature compensation can be introduced into the medium to be addressed. Transmitter Selection Rule 4, the temperature range of the transmitter: The transmitter is usually a two temperature calibration range, namely the normal operation temperature range and temperature range can be compensated. Normal operating temperature range is the transmitter in working condition will not be damaged when the temperature range, beyond the range of temperature correction may not reach performance of their applications. Temperature compensation range is smaller than the operating temperature range of a typical range. Working within this range differential pressure transmitter, the transmitter will certainly reach its proper performance. Temperature changes affect the output in two ways, one is zero drift; the second is the impact of full scale output. Such as: full scale +/- X% / ℃, reading +/- X% / ℃, when the temperature exceeds the range +/- X% of full scale, when the temperature compensation range of reading +/- X% Without these parameters it will lead to uncertainty in use. Changes to the degree of the transmitter output pressure changes caused by, or caused by temperature changes.
