Automatic process refractometer iPR – EX
The explosion protection version of the process refractometer consists of an intrinsically safe, single-certified sensor, which is installed in the hazardous area. The measuring signals are routed to the non-explosive area via a special cable (maximum length 500 m) and connected to 4 zener barriers. The connection to the central control system is realized with a RTU Modbus or serial RS 485 interface. Up to two measuring heads can be connected at the same time.
- Ex-protection version of the iPR-B3
- Suitable for all applications in explosion-proof areas
- Certified according to European Classification ATEX II 1 G Ex ia IIC T4 Ga
- Permanent inline real-time measurement of the concentration of dissolved solids
