Dwyer Instruments PMT2 Serie Installation Und Betriebsanleitung

Series PMT2 Particulate Transmitter
The 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
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.
• 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
