INTERNALLY SWITCHED MULTIPLE RANGE TRANSDUCERS

摘要

Systems and methods for an internally switched multiple range transducer are provided. In one embodiment, a method comprises receiving, at a first sensor, a pressure, wherein the first sensor is associated with a first pressure range; measuring, at the first sensor, the pressure to generate a first pressure signal; in response to determining that the first pressure signal is not associated with the first pressure range, activating a second sensor, wherein the second sensor is associated with a second pressure range that is different from the first pressure range; and measuring, at the second sensor, the pressure to generate a second pressure signal.

1. A method, comprising:
receiving, at a first sensor and a second sensor, a pressure, wherein the first sensor is associated with a first pressure range and the second sensor is associated with a second pressure range that is different from the first pressure range; measuring, at the first sensor, the pressure to generate a first pressure signal; measuring, at the second sensor, the pressure to generate a second pressure signal; converting the first pressure signal to a first digital signal indicative of the first pressure signal; converting the second pressure signal to a second digital signal indicative of the second pressure signal; determining, based on the first digital signal and the second digital signal, whether the received pressure corresponds to the first pressure range or the second pressure range; responsive to determining that the received pressure corresponds to the first pressure range, selecting the first digital signal for coupling to a digital output; and responsive to determining that the received pressure corresponds to the second pressure range, selecting the second digital signal for coupling to the digital output.
