Escort ELF® Sampling Pump

The Escort ELF Sampling Pump can be used for personal

and area sampling. The state-of-the-art electronic laminar

flow sensor, consisting of a laminar flow element and pressure

sensor, provides constant flow (volume) control, with

±2.5% regulation of flow rate (from 1 to 3 lpm) and automatic

compensation for changes in battery voltage, temperature,

altitude ,and sample load.

An internal secondary standard calibrates the pump

continuously and needs to be checked against a primary

standard only once a month (or every 200 hours for coal

mine dust sampling).U. S. Patent No.5,295,790.

Approvals

Escort ELF Sampling Pumps are NIOSH-certified for coal

mine dust sampling (TC-74-030).They are MSHA-certified

as intrinsically safe for underground use (Approval No.

2G-3924-1).The Escort ELF pump has been approved for

intrinsic safety by UL for use in Class 1,Groups A, B, C, D;

Class II, Groups E,F, and G; and Class III, Division I locations.

MSA Cassettes

Mining Detector Tube Set

Coal-Dust Sampling

MSA’s preweighed filter cassettes

consist of a sealed outer plastic

capsule and an inner preweighed

filter capsule. Each cassette is

supplied with a mine data card

for the weight of the filter

capsule to be recorded and

sent in a mailing carton

addressed to MSHA.

General-Purpose Cassette

The general-purpose cassette is a

sample cassette that can be used

for silica sampling. This cassette can

also be used for all airborne particulate

collection not limited to quartz

or silica.

This cassette is individually packaged

in a sealed plastic bag. Each

cassette is weighed by a robot to

.01 mg at 70°F +/- 5° and 455 RH

+/- 10%.Each cassette is attached

to a Dust Data Card which includes

the cassette serial number and

actual weight. The cassette inlet

contains a tamper-proof deflector

plate, and the outlet contains an                                           

anti-blow-back check valve.Both the

inlet and outlet openings are capped to ensure cleanness. The

perimeter of the cassette housing is sealed with tamper-proof

sealing tape.

Because of the extreme accuracy of the MSA weighing process,

users of this cassette can sample the atmosphere for dust particulate

and have the analytical analysis performed with complete

confidence in its accuracy.

General Purpose Cassette

For mine atmosphere sampling, the MSA preweighed

filter cassettes must be used with a Cyclone Assembly to collect the respirable dust fraction. The 10mm diameter assembly is used to separate respirable dust particles from non-respirable dust particles.
