1.产品描述：

MX-YL-188-05差压压力变送器是为流体工业应用所设计，可以测量液体、蒸汽和气体的压力。采用高精度单晶硅硅技术，保证传感器的高稳定性和高可靠性。

 Product Description:

Mx-yl-188-05 Differential pressure transmitters are designed for fluid industry applications to measure the pressure of liquids, vapors and gases. Adopt the world's leading high precision monocrystalline silicon technology to ensure the high stability and high reliability of the sensor.

本是一款外部供电、具有远传通讯功能的高精度智能变送器。应用领域是针对野外，露天场所等恶劣环境，如输油，输汽，供暖等输送能源管道等地方进行压力监测，实现信号有线远传，同时又加配HART协议，可以配合手操器使用，能够和国际仪表通用。配合无线通讯接收模块使用，上位机可直接使用组态实时监测采集数据，现场又带有高清LCD液晶显示，可以有效使工作人员直观观察到液位高度，并且可以根据被测介质密度的不同，随时更改测量范围和标定系数。

This is a high precision intelligent transmitter with external power supply and remote communication function. The application field is to carry out pressure monitoring in wild and open places, such as oil, steam transportation, heating and other transportation energy pipelines, so as to realize remote signal transmission by wire. Meanwhile, HART protocol is also added, which can be used with manual operator, and can be used perfectly in international instrument. With the use of wireless communication receiving module, the upper computer can directly use configuration real-time monitoring and data collection, and the field is equipped with high-definition LCD liquid crystal display, which can effectively make the staff visually observe the liquid level height, and can change the measurement range and calibration coefficient at any time according to the different density of the measured medium.

清零按键功能说明：：

本产品采用进口的单晶硅芯体，清零功能方面。在无压力的情况下，按M键5秒钟，显示屏左下面出现ZIRM字母时松手，然后连续按Z键三次，出现PV=0时，再连续按M键3次，显示屏左下方没有字母时候已经清零完毕。

This product adopts imported monocrystalline silicon core, with zero clearing function. Under no pressure, press M for 5 seconds, release when the ZIRM letter appears on the bottom left side of the display, then press Z three times in a row, PV=0, press M three times in a row, zero is cleared when there are no letters on the bottom left side of the display
