Series DPM Particulate Monitor

Brand: Dwyer Instruments, LLC

The DPM Particulate Monitor and PMS Particulate Sensor combine to provide a basic baghouse and cartridge filter leak detector designed for general maintenance planning and process protection.

It is easy to use and reliable. Leakage is gauged in real-time, on-the-spot, without prior baseline data and without signal tuning.

Simply apply power and the general condition of the filter is quickly determined. An alarm point is set by simply moving an indicator up and down the gauge with the convenient, lockable key pad. For more precise alarm setup the large display provides both a logarithmic analog bar graph and an absolute digital readout.

The log scale enables the user to observe both the baseline bleed through and the high peaks that are caused by filter cleaning cycles and developing leaks. Observation of both baseline and peaks is essential to setting proper alarms.

The digital readout in absolute units ensures correct interpretation of the readings and provides accurate historical comparisons.

The DPM Particulate Monitor is housed in a rugged cast aluminum enclosure. An LCD displays particulate levels in bar-graph and digital forms. A lockable membrane keypad is provided for setup and adjustment.
