The Ethernet system for temperature measurement MSX-E3211 has 16/8/4 differential inputs, 24 bit, for thermocouples or RTD (Pt100, Pt1000). Up to 8 channels can be acquired simultaneously. The system was developped for fast measurement directly at the sensor in the harsh industrial environment. It has a robust normed metal housing with the degree of protection IP 65 and an extended temperature range from -40°C to +85°C. The ARM®9 32-bit processor allows the calculation of the acquired values. The Development Mode allows to customise applications individually. Through synchro connection, several MSX-E systems can be daisy-chained and synchronised with one another in the µs range.
