在任何類型的水或廢水處理行業(yè)工作，可能需要一個(gè)投入式壓力變送器。這些投入式壓力變送器不僅非常且能夠連續(xù)讀取水平，而且?guī)缀蹩梢栽谌魏纬叽绲墓藁蛉萜髦惺褂?，與許多側(cè)面或其他安裝的流體開關(guān)相比具有明顯的優(yōu)勢(shì)。

Working in any type of water or wastewater treatment industry may require an input pressure transmitter. These input pressure transmitters are not only highly accurate and capable of continuously reading levels, but can be used in almost any size tank or container, providing significant advantages over many lateral or other mounted fluid switches.

accuracy level
Pressure gauges come in many different accuracy grades. The accuracy classes are specified in the ASME B40.100 (accuracy classes ranging from 0.1% to 5%) and EN 837 (accuracy classes ranging from 0.1% to 4%) standards. The accuracy grade specification is usually "percentage of the range" meaning that if the accuracy grade is 1% and the range is 0 to 100 psi, the accuracy is ± 1p.
Make sure you know the accuracy level of the instrument to be calibrated, as this will naturally specify an acceptable accuracy level, but it will also have other effects on the calibration process.
