Product Overview
PMDP Particulate Matter (PM) Sensors represent a technological breakthrough in optical PM sensors. This laser-scatter type sensor detects and counts particles using light scattering principles and features innovative contamination resistance technology to perform highly accurate and reliable PM measurements. The PMDP sensor is used for duct mount applications.
Over a ten-year lifetime, these sensors provide superior precision measurement of numerous PM types and higherresolution particle size binning, allowing for the detection of many types of environmental dust and other particles.
The PMDP detection concentration range is 0 to 1,000 μg/m³ and is intended for duct or outdoor mounting.
This versatile sensor offers selectable PM measurement options of PM1.0, PM2.5, PM4.0 and PM10.

NOTICE
PRODUCT DAMAGE DUE TO ELECTRO-STATIC DISCHARGE
Circuit boards and components can be damaged by static electricity or electro-static discharge (ESD). Observe the following electro-static precautions when handling this product and cables and components connected to the product.
- Keep static-producing material such as plastic, upholstery, carpeting, etc. out of the immediate work area
- Store the product in ESD-protective packaging when it is not installed in the panel
- When handling the product or a conductive cable/ESD-sensitive component connected to the product, wear a conductive wrist strap connected to ground through a minimum of 1 MΩ resistance
- Do not touch exposed conductors and component leads with skin or clothing
Failure to follow these instructions can result in equipment damage.
- Prepare the duct for installation by drilling holes to accommodate the probe tube. Ensure the gasket on the back is depressed to prevent leakage between the product and the duct. Do not over-tighten the screws.
- Ensure the probes are installed on the wall with no obstruction to airflow around the probe.
- Release the latch on the lid to access the DIP switches and terminal block.
- Wire the connections per the diagram in the Wiring section below. This device features spring terminals for screwless termination. Open the terminal point by inserting a screwdriver, then insert the wire above. Release the screwdriver to hold the wire in place. Details on wiring and configuration are contained in the next sections of this document.
- Secure the latch-on cover in the closed position and remove the clear protective mask on the front label of the device.

NOTICE
INACCURATE READINGS
- Do not run wiring in the same conduit as AC power wiring. Close proximity to AC power may inuence accuracy.
Failure to follow these instructions can result in reduced accuracy.
