8.1 PM700E
8.1.1 Overview
The PM700E external remote sensors extend the pressure measurement capability of a
DPI 610E unit. These sensors provide pressure measuring capability from 25 mbar up to
1400 bar, with ranges available in absolute, gauge and differential models. PM700E sensors are
available for both commercial and hazardous area environments. Any number of remote sensors
can be individually used with a single DPI 610E, because all sensors hold their own calibration
data.
8.1.2 Media Compatibility
Care must be taken to observe media compatibility when using the PM700E. Sensor variants up
to and including 3.5 bar, have exposed diaphragms, while 7 to 1400 bar variants are diaphragm
isolated.
