AW-P-20 series Microprocessor based digital pressure transmitter is a signal conditioned, media-isolated high             
precision device that can be used for wide variety of applications. It is a weter resistant, compact field case             
for complete protection from harsh environments.             
A compact field case and 4 digit LED local display make it easy to control process and adjust the value for             
measuring range, damping, zero & span.              
They are available as absolute and relative pressure types with either 2-wire current or 3-wire voltage output.             
The pressure to be measured acts through thin corrosion resistant stainless steel 316L diaphragm on a             
piezoresistive silicon measuring element. The transmitting meduim of pressure is oil. The measuring element             
contains diffused piezoresistive resistors which are connected into a Wheatstone bridge. The output signal of             
the bridge is temperature compensated and converted into a standardized current or voltage output signal.
