Siemens is extending the Sitrans P family of its pressure transmitter portfolio. By adding the newly developed Sitrans P310 and P410 to the Basic and Advanced segments and the proven Sitrans P500 in the Premium segment, Siemens is now able to offer the right device class to address every conceivable measurement requirement. The proven Sitrans P DS III has also been technically innovated. The new developments deliver even more accurate measurement results across the whole pressure transmitter range.
The Sitrans family provides a high-precision product portfolio to cover any conceivable measurement need with its comprehensive range of device classes, from the Basic model, the P310, through the Advanced Sitrans P410 to the proven Premium Sitrans P500. The P310 pressure transmitter offers a measurement accuracy of 0.075 percent, making it ideal for applications in fields such as water supply and disposal.
With its extreme measurement accuracy of 0.04 percent, when used in combination with an orifice meter the Sitrans P410 is ideally suited for applications such as the flow measurements required when filling and emptying gas tanks. The same applies to pressure measurements for process gases or fluids in low and high pressure applications up to 700 bar. The Sitrans P500 rounds off the Sitrans P family in the Premium segment with standard measurement ranges from 50 mbar to 32 bar. In terms of performance, precision, long-term stability and diagnostic scope, the differential pressure transmitter is capable of coping with the most stringent demands. With a response time of 88 ms and an ability to operate in temperatures of -49°C to +125°C (-56.2 °F to 257 °F), the Sitrans P500 is ideally suited for the ultra-precise measurement of differential pressure, filling level and flow rate.
Still available is the tried and tested Sitrans P DS III. This product from the Advanced segment has been innovated to feature premium sensor technology, bringing about an improvement in both basic accuracy and temperature range, as well as optimizing measurement deviation to 0.065 percent with a turndown of 1:1 to 5:1. This allows plant efficiency to be further increased when performing processes such as level measurement, as the new technology enables better utilization of shut-off limits for tank filling levels. These improvements and the wider relative pressure range, which has been extended with a 250 mbar cell, make this the highest performing transmitter for flue gas measurements in power stations and incineration plants.
All of the transmitter series are simple to operate using just three push buttons, and offer a long-term stability of 0.125 percent over a period of five years, allowing calibration cycles to be extended and maintenance work reduced with all the associated cost savings. They are also certified to SIL 2/3 and dispose the commonly required Ex zone certifications.
