Valmet MBMT120 Temperature Transmitter Module
Valmet MBMT120 is a multi-channel temperature measurement transmitter module for Valmet DNA automation system. It receives RTD or thermocouple signals from field sensors, converts raw thermal signals into digital data and communicates with the DNA controller for pulp, paper and energy process temperature monitoring.
This module provides high noise immunity for harsh mill environments, supports sensor break detection and channel self-diagnosis. It adopts DIN rail rack mounting and hot-swap compatible design. Widely used in pulp & paper, power and chemical plant DCS maintenance, spare replacement and control system retrofit projects.
