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 as particles pass near the probe. The transmitter provides a 4-20 mA signal that varies with particulate levels, offering 6 sensitivity ranges for user selection. Features include a non-stick PTFE coated probe to prevent erroneous readings from moisture and dust buildup, and remote zero calibration for reduced maintenance. It is ideal 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
- Emission monitoring
