Disclosed herein are advantageous measuring devices, and systems of the present disclosure and adjustment methods/techniques thereof. The present disclosure provides improved measuring devices (e.g., pressure/temperature measuring devices), and improved systems/methods for adjusting one or more features (e.g., offset and/or span) associated with measuring devices. More particularly, the present disclosure provides sealed measuring devices (e.g., sealed signal conditioning devices, such as sealed pressure transducers or transmitters) having adjustment members (e.g., magnet members) that allow a user to adjust the offset and/or span of the sealed measuring devices. The measuring devices include an adjustment member that allows a user to make adjustments to one or more features of the measuring devices. For example, a sealed pressure transducer can include an magnet member that allows a user to make fine (precision) adjustments of output offset and/or span (e.g., in the field), without breaching the enclosure or housing of the measuring device.

Adjustment member for measuring devices

A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, pressure measurement may include a signal-converting circuit that includes a coupler, a signal biaser, and a signal span adjuster. The coupler is operable to receive a pressure-representative signal, and the signal biaser includes a thermally-insensitive voltage divider that facilitates biasing the pressure-representative signal. The signal span adjuster is coupled to the coupler and the signal biaser and includes a thermally-insensitive voltage divider that facilitates adjusting the span of the pressure-representative signal.
