Product Specifications Purchase of 4” Vane Anemometers

Justification:

MSHA inspectors are responsible for determining if sufficient quantities of air are being provided in active working areas of the mine environment. The assurance of sufficient air quantities is related to the prevention of the build-up of explosive gases and necessary to assure a sufficient air quantity to dilute and render harmless, the gases and dust present in the mine environment. The requirements for specific air quantities are stated in 30 CFR part 75 Subpart D. These instruments are subjected to the harsh mining environment which affects the instruments reliability. The inspectors must carry many instruments into the underground mine where at times space is very limited, so the compact size is very important. This requirement is for the purchase of 134 low speed 4” ball bearing vane anemometers and 40 high speed 4 inch vane anemometers.

Brand name products are as follows: Davis Low Speed – CSE part # 0141700024, Davis High Speed CSE part # 0141700034, ST-1000 High Speed, ST-1000 Low Speed Anemometers.

Products that meet all of the following salient characteristics (specifications) are considered equal:

Low Speed

· The unit and readout must not be affected by electromagnetic sources or radio frequency interference

· The unit should provide for display of the air velocity in feet

· The unit must be proven to provide reliable results in the harsh underground coal mine environment

· The unit must have a metal housing to withstand the underground coal mine environment

· The unit must be able, with proper calibration, to provide results that are traceable to NIST

· The unit must be MSHA approved as permissible for use in underground coal mines and/or MSHA certified as intrinsically safe

· Measurement range of 40 to 5,000 FPM

· Be delivered with NIST traceable calibration

High Speed

· 4” high speed vane anemometer

· The unit and readout must not be affected by electromagnetic sources or radio frequency interference

· The unit should provide for display of the air velocity in feet
