Monitoring Instruments

Provide the following monitoring instruments in addition to the monitor and

safety controls. Pressure gages shall conform to ASME B40.1, 115 mm 4 1/2

inch diameter, red marking pointer, single bourdon tube, brass case, black

enamel finish. Provide pressure gages with a pressure snubber and a

stainless steel barstock needle isolation valve. Thermometers shall be

extended stainless steel sheathed bimetallic stem, 90 mm 3 1/2 inch dial,

and separable 100 mm 4 inchstainless steel wells. Temperature measurements

at inaccessible locations shall be made with remote reading thermometers

conforming to MIL-T-19646, Class C separable well of Type 304 stainless

steel. Select pressure and temperature gage ranges to give a normal

operating reading near the midpoint of the scale range.

a.

Oil cooler outlet temperature gages for oil.

b.

Oil cooler inlet and outlet temperature gages for water.

c.

Lubrication oil pump discharge pressure gage.

d.

Inlet air filter differential pressure gage with 1992, zero, 1992

Pa 8, zero, 8 inch water gage. Provide selector valve, tubing,

and tap to measure static gage pressure downstream of each filter

stage.

e.

Total running time readout.

f.

Interstage air pressure gages for each interstage.

g.

Cooling water supply to compressor pressure gage.

h.

Cooling water return from compressor pressure gage.

i.

Compressed air pressure downstream of aftercooler pressure gage.
