Absolute Maximum Ratings
The extreme limits that a product can withstand without damage to the product. Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may de-grade product reliability
-
Absolute Pressure
A measure relative to perfect vacuum or zero pressure reference.
-
Absolute Pressure Sensor
Product whose output is proportional to the difference between the pressure applied in relation to relative zero pressure (a total vacuum on one side of the diaphragm) reference.
-
Accuracy
The maximum deviation of the actual output signal of a device to the true value of the input pressure measured over the compensated pressure range at reference temperature. The various errors such as (linearity, hysteresis, repeatability and temperature shift) attributing to the accuracy of a device are usually expressed as a % of span.
-
Analog Output
An electrical output from a transducer that changes proportionately, with any change in input pressure.
-
Atmospheric Pressure
The total outside air pressure measured with reference to absolute vacuum. The pressure varies depending on geographical location, altitude and local weather conditions.
-
Auto Zero
Typically, a zero pressure reference such as atmospheric pressure (or equal pressures on both pressure ports for a differential product) is employed to allow the external correction of Offset Error. Usually done by using a microprocessor to open a solenoid valve at a predetermined time interval. This references atmospheric pressure to both sides of the gauge pressure transducer. The microprocessor reads the output voltage and makes the new null point. This method is used to eliminate errors due
