Barometric Pressure Transmitter, RS485 Interface
Atmospheric pressure transmitter. Outdoor, indoor use.
Barometric pressure transmitter for outdoor and indoor use. Display reading and pressure output is user selectable in these units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2.
Measured pressure values are converted to RS485 serial output. Transmitter circuitry is galvanically isolated from power circuitry to prevent collision in RS485 network.
Serial output RS485 - transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 1 to 255. Communication speed is 110 to 115200Bd.
