ОбзорThe SITRANS P300 is a digital pressure transmitter for gage and absolute pressure. All conventional thread versions are available as process connections. In addition, various hygiene-based connections and flange connections with front-flush diaphragms meet the requirements of a dead space free process connection. The output signal is a load-independent direct current from 4 t 20 mA or a PROFIBUS PA signal, which is linearly proportional to the input pressure. Communication is over HART protocol or over PROFIBUS PA interface. Convenient buttons for easy local operation of the basic settings of the pressure transmitter. The SITRANS P300 has a single-chamber stainless steel casing. The pressure transmitter is approved with "intrinsically safe" type of protection It can be used in zone 1 or zone 0. ;Область примененияThe pressure transmitter is available in versions for gauge pressure and for absolute pressure. The output signal is always a load-independent direct current from 4 to 20 mA or a PROFIBUS PA signal, which is linearly proportional to the input pressure. The pressure transmitter measures aggressive, non-aggressive and hazardous gases, as well as vapors and liquids. It can be used for the following measurement types:
With appropriate parameter settings, it can also be used for the following additional measurement types:
The "intrinsically-safe" EEx version of the transmitter can be installed in hazardous areas (zone 1). The transmitters are provided with an EC type examination certificate and comply with the respective harmonized European standards of ATEX. Gauge pressureThis variant measures aggressive, non-aggressive and hazardous gases, vapors and liquids. The smallest measuring span is 0.01 bar g, the largest 400 bar g (0.15 psi g, the largest 5802 psi g). LevelWith appropriate parameter settings, the gauge pressure variant measures the level of aggressive, non-aggressive and hazardous liquids. For measuring the level in an open container you require one device; for measuring the level in a closed container, you require two devices and a process control system. Absolute pressureThis variant measures the absolute pressure of aggressive, non-aggressive and hazardous gases, vapors and liquids. The smallest measuring span is 0.008 bar a, the largest 30 bar a (0.12 psi a, the largest 435 psi a). ;Заказные данные
