Controller of thermocouple suspensions KTT-15
The controller of thermocouple KTT-15 enables automatic multi-channel temperature data acquisition from thermocouple suspensions based on analog thermocouple temperature sensors.
The controller of thermocouple spensions is part of the local unit (LU) and provides automatic measurement, fixation, memorization and output to external sources of temperature values at controlled points.
Measurement of thermocouple EMFs is performed by a precision 24-bit ADC. Channel switching is accomplished using high-quality electronic switches. The controller features galvanic isolation for both the power supply and RS-485 interface circuits.
