Product Exclusive: Faster, more accurate pressure transmitter

Siemens expands pressure transmitter portfolio with Sitrans p500 with response time of 88 ms and reference accuracy of 0.03% for quick, accurate responses to process changes.


Siemens expands pressure transmitter portfolio with Sitrans p500 with response time of 88 ms and reference accuracy of 0.03% for quick, accurate responses to process changes.Siemens Industry Process Instrumentation & Analytics Business Unit (PIABU) has expanded its portfolio of pressure transmitters with the introduction of the Sitrans P500 product line, combining a response time of 88ms and reference accuracy of 0.03%, the Sitrans P500 quickly and precisely responds to process changes.

“Our customers are using these products in more complex applications in process industries, thus requiring the development of the Sitrans P500, which features extended functionality and increased accuracy to set a new standard in measuring precision,” said Michael Cushing, product marketing manager for Siemens Industry PIABU.

With a reference accuracy of 0.03% and a turndown of 200:1, working close-coupled in rugged conditions with maximum process temperatures of 125 °C (257 °F) is not a problem for the P500. Temperature compensation and a separate static pressure sensor minimize temperature and pressure errors.

Using the P500 reduces the need to stock different transmitters, as the product features long-term stability of 0.05% over 5 years (0.08% over 10 years). With dimensions of (3.4-inch w x 7.4-in. h x 5.5-in. d), the new transmitter is compact in design and low in weight (7.3 lb). It is said to be well-suited for high demand applications of the chemical, petrochemical, oil and gas and power industries.

With the new Local User Interface (LUI), users can configure the device quickly and simply at the transmitter. User-friendly functions include local configuration using full-text-enabled and multilingual backlit display, including graphical representation of process variables using bar graphs, curves and trend diagrams. It can also be operated and configured using standard HART tools with the help of a fast start wizard.
