衬塑压力变送器|压力变送器部件-华恒变送器 厂家

 在任何类型的水或废水处理行业工作，可能需要一个投入式压力变送器。这些投入式压力变送器不仅非常且能够连续读取水平，而且几乎可以在任何尺寸的罐或容器中使用，与许多侧面或其他安装的流体开关相比具有明显的优势。

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.
