Media Isolated, Field Adjustable Pressure Sensor
OVERVIEW
The AST4310 is a media isolated, field adjustable pressure
transmitter suitable for use in hazardous areas. Protected
by a Viton O-ring, this transmitter’s two potentiometers have
the ability to adjust the zero and span output signals up to
± 5% [of the full scale pressure]. Additionally, the AST4310
offers access points through the housing of the transmitter in
order to simplify adjustments after installation. Complete with
a wide range of threads, pressure ranges and output signals,
the AST4310 is the solution for pressure measurement when
adjust ability is necessary.
