nnnn

Test stands, compressor control,

nnnn

hydraulic systems, process automation,

nnnn

pump and pneumatic systems control

nnnn

nnnn

The Ashcroft® A2 pressure transmitter

nnnn

is ideal for a broad spectrum of pressure

nnnn

sensing requirements found in heavy

nnnn

industrial, and test and measurement

nnnn

applications. It offers the instrument speci-

nnnn

fier a wide choice of construction and per-

nnnn

formance variables.

nnnn

The Ashcroft® A2 is designed and manu-

nnnn

factured to provide the user with accurate,

nnnn

reliable, and stable output data. This is

nnnn

accomplished through the use of an on

nnnn

board microprocessor, that is programmed

nnnn

during a unique digital compensation

nnnn

process, to provide extremely linear and

nnnn

precise performance over the entire speci-

nnnn

fied pressure and temperature range .
