Installation requirements and calibration methods for wireless pressure sensors

Installation requirements and calibration methods for wireless pressure sensors

Wireless pressure sensors in the petrochemical, environmental protection, metallurgical and other industries have this irreplaceable role, we can see the importance of wireless pressure sensors in these areas. Therefore, the installation and calibration must meet the requirements. The following briefly describes its method.

Wireless pressure sensor installation precautions

First, before installation, check whether the accessories are complete and whether the fasteners are loose. Second, when installing, pay attention to gently, cut and knock, and drop. Finally, after installation, check that the wiring is reversed.

Wireless pressure sensors also need calibration. There are three main calibration methods:

1 One point calibration method: This calibration method compensates for offset error by eliminating drift at the zero point of the transfer function. This type of calibration method is often referred to as auto-zeroing. Offset calibration is usually performed at zero pressure, especially in differential sensors, because the differential pressure is normally zero under nominal conditions.

Sex errors usually have a uniform form, which can be obtained by calculating the average linearity error of a typical example and determining the parameters of the polynomial function (a×2+bx+c). The models obtained after determining a, b, and c are valid for the same type of sensor. This method can effectively compensate for linear errors without the need for a third calibration point.

It is very important for us to understand the installation considerations and calibration methods of wireless pressure sensors. Although wireless pressure sensors are not widely used today, wireless pressure sensors are bound to be widely used as people become more and more popular with wireless sensors. .
