The Ethernet system for length measurement MSX-E3701 / MSX-E3700 has 8/16 inputs for inductive transducers (Half-Bridge, LVDT, Mahr oder Knaebel) and 1 digital output, 24 V, with compare logic. The system was developped for the dynamic lenght measurement in the harsh industrial environment. It has a robust normed metal housing with the degree of protection IP 40 (MSX-E3700) or IP 65 (MSX-E3701) 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.
