AW-P-70 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 even in explosive area. 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.
