Nowadays, we are witnessing technological advances in industrial processes and controls with the advent of microprocessors and electronic components, the Internet, etc., as everything facilitates operations and guarantees of process optimization and performance and operational safety.
This advance today allows pressure transmitters, as well as other variables, to be designed to guarantee high performance in measurements, where previously we only had analog technology.
The analog transmitters then in use were designed with discrete components susceptible to deviations due to temperature, process and local conditions, which required constant adjustments through potentiometers and switches. Digital technology also provided simplicity in use.
Pressure transmitters are widely used in processes and applications with numerous features and resources.
It is worth remembering that in the last decades a wide variety of equipment has reached the market in several applications. The accuracy of the pressure characterization was really valued when it could be translated into measurable values.
The entire pressure measurement system consists of the primary element that will directly or indirectly come into contact with the process where pressure changes occur and the secondary element (the pressure transmitter) that will translate this change into measurable values ??to be used in the process.
Static or accurate performance depends on how well the pressure transmitter is calibrated and for how long it can maintain its calibration. Accuracy is often confused with precision, where accuracy is associated with the proximity of the value and precision is related to the dispersion of the values ??resulting from a series of measurements.
Calibrating a pressure transmitter involves adjusting zero and span. Accuracy usually includes effects of non-linearity, hysteresis and repeatability.
