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.
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
