Temperature Transmitter MTP 302-1

Failsafe High Speed Thermocouple Transmitter The MTP 302i has been specially developed for processes where safety and reaction speed are crucial. A typical example is high-pressure polymerization processes such as those used in the production of LDPE. A high degree of integration allows transmitting temperature values in less than 4 ms. The MTP 302i features an additional 4-20 mA output displaying three times the measurement range of output one. This way, the second output can still measure the temperature values, even if the measurement range of the first output is exceeded.
