商品説明
The PX971 is no longer available. Please see the PX01 Series as a substitute or contact Pressure Engineering.
Omega’s PX971 smart pressure transducers combine the best features of analog and digital transducers into a high accuracy, competitively priced unit designed to meet the most demanding applications. All models have both a 0-5 volt dc analog output and bidirectional serial communications output, which can be used simultaneously. Serial outputs are available in either RS-232 or RS-485 format.
The bidirectional communications allows the user to read data from the PX971 as well as change the configuration. Some of the items the user can configure include zero and span, pressure units, sampling and update rates.
The PX971 combines a proven silicon piezoresistive sensor with a microprocessor for compensation. The result is a transducer with exceptional accuracy (0.05% full scale typical) over it’s full temperature range of -40 to 85°C (-40 to 185°F).
