PMT2 Series Particulate Transmitter
The PMT2 Series Particulate Transmitter is designed to measure particulate levels in emissions from dust collectors. Utilizing DC-coupled electrostatic induction sensing technology, it monitors the pA current generated by particulates passing near the probe. A 4-20 mA signal varies with particulate levels. The PMT2 offers 6 sensitivity ranges for user selection and features range and test selection switches for outputting 4 mA or 20 mA signals, aiding in setup and troubleshooting. An averaging time setting can suppress signals if needed.
Features & Benefits
- Simple 2-wire installation for PLCs and control panels.
- Non-stick PTFE coated probe prevents erroneous readings from moisture and conductive dust, condensation, and dust buildup.
- Remote zero calibration reduces maintenance time.
Applications
- Emissions monitoring
- Bag break detection in dust collectors
- Filter leak or wear detection
- Bin vent monitoring
