However, devices with a valve plug can be fitted with the optional local display PHX20. A 1-line liquid crystal display (LCD) is used. The local display shows measured values, fault messages and information messages. The device display can be turned in 90° steps. Depending on the orientation of the device, it is therefore easy to read the measured values. ## 7.1.1 Storage conditions - Use original packaging. - Storage temperature range: –30 to +80 °C (–22 to +176 °F) ## 7.1.2 Installation **==> picture [387 x 88] intentionally omitted <==** **----- Start of picture text -----**<br> 1 2 3 4<br> A0022208<br>**----- End of picture text -----**<br> 1.

Internal temperature compensation is faster the smaller the change in temperature and the longer the time interval. For further information please contact your local Endress+Hauser Sales Center. ## 12.5.2 Pressure specifications ## L[WARNING] The maximum pressure for the measuring device depends on the lowest-rated element with regard to pressure. - ‣ For pressure specifications, see the "Measuring range" section and "Mechanical construction" section in the Technical Information. - ‣ The Pressure Equipment Directive (2014/68/EU) uses the abbreviation "PS". The abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring device. - ‣ MWP (maximum working pressure): The MWP (maximum working pressure) is specified on the nameplate. This value is based on a reference temperature of +20 °C (+68 °F) and may be applied to the device for an unlimited period of time. Observe the temperature dependency of the MWP. - ‣ OPL (over pressure limit): The test pressure corresponds to the over pressure limit of the sensor and may only be applied temporarily to ensure that the measurement is within the specifications and no permanent damage develops. In the case of sensor range and process connections where the over pressure limit (OPL) of the process connection is smaller than the nominal value of the sensor, the device is set at the factory, at the very maximum, to the OPL value of the process connection. If you want to use the entire sensor range, select a process connection with a higher OPL value.
