SERIES PMT2 | PARTICULATE TRANSMITTER
®
FEATURES/BENEFITS
• Simple 2-wire installation for PLC and control panels
• Non-stick PTFE coated probe to prevent false readings from moist and conductive dusts, condensate, and dust buildup
• Remote zero calibration helps to decrease maintenance time
DESCRIPTIONAPPLICATIONS
• Emissions monitoring
• Broken bag detection in dust collectors
• Filter leak or wear detection
• Bin vent monitoring
The Series PMT2 Particulate Transmitter 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; a 4-20 mA signal will
vary based on the particulate level. The PMT2 offers 6 sensitivity ranges allowing the user to choose
the range that will best t the application. The range and test selector switch can also be set to output
a 4 mA or 20 mA signal to assist with set up or trouble shooting. Averaging time setting can be used to
dampen the signal if desired.
