PMT2 Series Particulate Transmitter
The PMT2 Series Particulate Transmitter is designed to measure particulate levels in dust collector emissions. Utilizing DC-coupled electrostatic induction sensing technology, it monitors the pA current generated by particulates passing near the probe. The transmitter provides a 4-20 mA signal proportional to the particulate level and offers 6 sensitivity ranges for user selection. Features include digital damping, a non-stick probe for accurate readings in challenging environments, and remote zero calibration for reduced maintenance. It is suitable for PLC and control panel integration with a simple 2-wire installation.
Features & Benefits
- Simple 2-wire installation for PLC 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 leak detection in dust collectors
- Filter leak or wear detection
- Bin vent monitoring
