Absolute pressure transmitter , differential pressure transmitter

We special supply Siemens pressure,flow,temperature products , contact us to get better prices!

The 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 to 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.

SITRANS P300 Application

The pressure transmitter is available in versions for gage 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, nonaggressive and hazardous gases, as well as vapors and liquids.

It can be used for the following measurement types:
• Gage pressure
• Absolute pressure
With appropriate parameter settings, it can also be used for the following additional measurement types:
• Level
• Volume
• Mass
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.
Gage pressure
This variant measures aggressive, non-aggressive and hazardous gases, vapors and liquids.
The smallest measuring span is 10 mbar g, the largest 400 bar g.
Level
With appropriate parameter settings, the gage 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 pressure
This variant measures the absolute pressure of aggressive, nonaggressive and hazardous gases, vapors and liquids.
The smallest measuring span is 8 mbar a, the largest 30 bar a.
