Introduction
The TEOM 3600 Personal Dust Monitor (PDM), manufactured for
miners by Thermo Fisher Scientific, incorporates a real-time particulate
monitor that measures respirable coal dust mass concentration, shift
exposure, and accumulated exposure in real time. The TEOM 3600 PDM
(
Figure 1–1 ) has a cap-lamp assembly, power takeoff (PTO) connector and
two battery packs. The monitor is suitable for personal and area monitoring
in underground mines, or other occupational environments with elevated
particulate concentrations. The PDM is a wearable device that sets up
quickly, delivers accurate results, recharges quickly and is easily serviced.
The PDM contains all the hardware and software necessary to measure and
store ambient particulate mass concentration. The mass measurement is a
filter-based direct mass monitoring instrument using Thermo Scientific’s
patented TEOM and momentum compensation technologies. The flow
control system maintains a constant volumetric flow at 2.2 l/min and total
filter loading to 6 inches-Hg (20.32 kPa)
