SERIES PMT2 | PARTICULATE TRANSMITTER dwyer-inst.com DWYER INSTRUMENTS, INC. ® T: 219-879-8000 | F: 219-872-9057 | info@dwyermail.com 800-872-9141 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 APPLICATIONS • Emissions monitoring • Broken bag detection in dust collectors • Filter leak or wear detection • Bin vent monitoring DESCRIPTION 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 to 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 fit 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.
