Multi-parameter differential pressure transmitter Qingdao the Obo intelligent high precision multi-parameter transmitter for industrial pipe Fluid flow measurement, such as gas, liquid, vapor, and other media. The intelligent high-precision multi-parameter transmitter is characterized by a small pressure loss, range, high precision, almost from the impact of fluid density, pressure, temperature, viscosity and other parameters in the measurement of volume flow of the working conditions. No moving mechanical parts, so the intelligent high-precision multi-parameter transmitter and high reliability, low maintenance. The instrument parameters can be long-term stability. Intelligent high-precision multi-parameter transmitter piezoelectric stress sensors, high reliability, can work in the operating temperature range of -20 ℃ ~ +250 ℃. Analogue standard signals, digital pulse signal output, easily supporting the use of computers and other digital systems, is a more advanced and ideal flow meter ● For all differential pressure flow sensor ● battery-powered site without an external power supply ● isolated output Super anti-jamming design, shielding all interference ● output pulse, the current (4-20mA), 485 the (modbu Kaubamaja) signal (requires an external power supply) ● own temperature and pressure sensors ● gas, steam, automatic temperature pressure compensation ● range than 1:100 1:200 1:400 ● precision 0.1 0.2 0.5 ● gas temperature, pressure, flow of the working conditions, standard conditions, flow parameters ● steam temperature, pressure, density, mass flow can be displayed etc. parameter
