Dwyer Instruments Series PMT2 Particulate Transmitter

Click2Contact

The Series PMT2 Particulate Transmitter, from Dwyer Instruments, is designed to measure particulate emission levels from dust collector discharge. Using DC-coupled, electrostatic, induction-sensing technology, the transmitter monitors a pA current that is generated as particulate passes near the probe and transmits a 4–20 mA signal that will vary based on the particulate level.

The product offers six sensitivity ranges, allowing the user to choose the range that will best fit the application. The range and test selector switch can also be set to output a 4 or 20 mA signal to assist with set-up or troubleshooting. Averaging time setting can be used to dampen the signal if desired.

Applications include emissions monitoring; broken bag detection in dust collectors; filter leak or wear detection; and bin vent monitoring.
