Relative pressure transmitter PAA35X series

absolute4-20 mA0-10 V

The high accuracy of these Pressure Transmitters can reach 0.01% FS. This series is equipped with an electronic evaluation system based on micro-controllers to ensure maximum accuracy. Each transmitter is calibrated along the entire range of pressure and temperature variations. This measurement data is used to develop a mathematical model that allows all systematic errors to be corrected. The interface consists of a robust semi-duplex RS485 for 9,600 and 115,200 baud. All products, with the exception of the version with the DIN 43650 socket, are equipped with an external pass-through plate for the interface. Communication protocol: KELLER bus and MODBUS RTU. With the CCS30 software it is possible to configure transmitters and save measurement values: Reading of the currently measured values ​​for pressure and temperature, with maximum resolution. Speed: at 115,200 baud, up to 330 measured values ​​per second (compatibly with the converter) Retrieving information and status (pressure and temperature ranges, serial code, software version, etc.) Reprogramming of the analog output (e.g. different units of measurement or pressure ranges) Calibration: you can adjust the zero point and amplification Special processing, such as the adaptation of a non-linear curve, or the calculation of the root for flows Ability to adjust the low pass filter and communication parameters.
