PMX Particulate Monitor Overview

Monitor smoke and airborne particulates with the PMX particulate monitor. The device combines proven sensor technology with innovative hardware to provide an easy-to-use system for monitoring light transmission in a wide variety of applications. Ideal for industrial ventilation hoods and commercial kitchen ventilation applications.

OEM Particulate Monitor Integration or Standalone

Our particulate monitor is available in two styles: circuit boards for OEM applications and NEMA 4X housings to protect the components while providing a high-quality, durable window for light transmission measurement. The transmitter is mounted up to 10 meters from the receiver module, then aligned and adjusted to focus the light onto the receiver. The illumination level is adjusted for the optimum operation at the distance and light transmission range necessary for the specific application. An adjustable threshold level allows the operator to set the discrete output switching point.

Intuitive Setup

Featuring a 2-digit display that provides an indication of signal strength making set-up and integration quick and easy. The PMX sensor provides both a discrete PNP/NPN output and a 0-5V analog output. The analog output can be monitored allowing the external system to log variations and take action, such as activating exhaust fans.

Energy Saving Advantage

Currently, in the commercial kitchen hood market, ventilation is activated in the morning and stays active until the facility closes at night. The PMX sensor will enable the kitchen hood ventilation unit to be activated and adjust its speed based on the amount of smoke generated by the food being cooked. Overall, the PMX allows ventilation to be based on actual ventilation demand and not just be a static operation, which is a significant energy and cost savings.
