The Beka BR323 series consists of ATEX certified, explosion-proof (Ex d), loop-powered displays in aluminum or stainless steel housing. The configuration and calibration can be performed with a simple Windows software via a serial communication cable. Measurement units can be displayed on an alphanumeric five-digit display under the numeric display. The characters are entered via the configuration software and are memorized by the instrument when the 4-20 mA is disconnected.
