PMT2 Series Particulate Transmitter
The PMT2 Series Particulate Transmitter is designed to measure particulate levels in dust collector emissions. Utilizing DC-coupled electrostatic induction sensing technology, it monitors the pA current generated as particulates pass the probe. The transmitter provides a 4-20 mA signal proportional to the particulate level and offers 6 sensitivity ranges for application-specific selection. Features include digital damping, a non-stick probe for accurate readings, and remote zero calibration for reduced maintenance. It is ideal for emission monitoring, bag leak detection in dust collectors, filter leak or wear detection, and bin vent monitoring.
