The i2C interface provides complete integration flexibility, enabling localised bus configuration, which gives the user serial communications with the sensor. This synchronous master-slave interface enables communication between a master and up to 127 slave devices. As well as typical settings such as slave address and data format, units for pressure and other parameters can be set up.
Providing long term stability and thermal behaviour, the DCT 532 is a modularly designed pressure sensor, allowing the customisation of mechanical and electrical connections to suit specific customer applications. The sensor is also claimed to offer fast response times and a measuring rate of 500Hz, which means no lag or downtime on the digital bus network.
The DCT 532 is available in nominal pressure ranges from 0-100mbar up to 0-400bar. Accuracy is 0.35% FSO to IEC 60770 and so includes all setting errors, making this a high accuracy level-measuring instrument. The sensor provides a high level of electrical protection to prevent damage once the unit is installed in the field. Output signal is 3.5-5.5Vdc. The sensor is claimed to be accurate even in fluctuating temperatures from -25 to 125°C.
Optional versions of the sensor include a welded sensor and a G ½” flush pressure port up to 40bar.
