1 DRS Monocrystalline silicon smart differential pressure transmitter DRS300 High stability Detailed Information application the flow of gas, vapor and liquid measurement with device (volume or mass flow) Measurement of level, volume and mass Differential pressure monitoring Through a number of international certifications, widely used DRS 300 smart differential pressure transmitter uses monocrystalline silicon sensor chip and world's original design of monocrystalline silicon suspension that made of advanced MEMS technology, so it achieves the world's leading overpressure performance and also ensures excellent signal stability. Built-in manometry capsule and signal processing module that are imported from Germany achieve the perfect combination of static pressure and temperature compensation, which provides high measurement accuracy and stability under a wide range of static pressure and temperature. DRS 300 smart differential pressure (flow) transmitter can measure differential pressure accurately and convert it into DC4 ~ 20mA output signal. This transmitter can be operated through three-button locally or through universal communicator or configuration software remotely. Without affecting the output signal of DC4 ~ 20mA, it can display and configurate at the same time. Benefits High accuracy Differential pressure (flow) transmitter can measure high accurately in the 0.5 ~ 500kPa measuring range. The accuracy of standard calibration range: ±0.05% Positive and negative zero shift, without adjusting linearity Excellent overvoltage performance within a small range overpressure of 1kPa nominal range chip: 1.5MPa overpressure of 4kPa nominal range chip: 2.5MPa Excellent suitability of environment The intelligent static pressure and temperature compensation protect transmitter from the effects of temperature, static pressure and overpressure, so that the consolidated measurement error will be kept to the minimum. Flexible range of compression M1,M2 Range ratio: 20:1 M3 Range ratio: 40:1 M4,M5,M6 Range ratio: 100:1 Excellent operability & convenient use Five-digit LCD with backlight View of units (Pa, kpa, MPa, bar, mbar, %, psi, mmh 2 o) Quickly adjusted through built-in three buttons A variety of corrosion-resistant materials Comprehensive self-diagnosis function
