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 that varies with particulate levels and offers 6 sensitivity ranges for user selection. Features include digital damping, a non-stick probe for reliable readings, remote zero calibration, and adjustable averaging time to suppress signal fluctuations. It offers simple 2-wire installation for PLCs and control panels.
