URX1 – Intrinsically safe process refractometer

The URX1 digital refractometer is designed specifically for hazardous areas up to Zone 0: the equipment certificate is ATEX II 1 G – EEx ia IIB T4. You may simply install the unit in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with high accuracy. It also features a user programmable scale for specific applications. The URX1 will signal to the process when concentration is outside of specifications or has reached its target end point by means of analogue and digital interfaces (Profibus DP is available as an option). The analyzer does not have any drift in the time so that it does not need any adjustment vs the laboratory: after the initial configuration during start up, the operators in the plant do not have to touch the system anymore. Due to the optical technology, the equipment is virtually no maintenance: the robust construction with stainless steel case and IP67 protection, allows the installation in any aggressive environment using various Maselli mounting adapters including weld ends, flanges and DIN 11851.
