Differential pressure regulator with measuring line cleaning
The HE 5422 MR is a differential pressure regulator for differential pressure ranges of 0…35 mbar, 0…90 mbar or 0…450 mbar. As a highlight, the 2-in-1 solution also comes with integrated measuring line cleaning. This permanently prevents possible incorrect measurements. Temperature fluctuations at the place of use often cause condensation in the measuring lines.
The internal test lead cleaner reliably flushes the test leads at specific intervals. The compact “2-in-1” device facilitates installation and eliminates the need to coordinate between the differential pressure regulator and a separate measuring line cleaner.
The wide range power supply for 100 – 240 V AC, as well as for 24 V DC allows the differential pressure controller to be used worldwide. The controller is set either via the membrane keypad directly on the device or via service PC using the USB/TTL adapter (option) and the ” EasyTool Controls” software.
The cleaning range of the compact controller is defined by a lower and an upper threshold. For automatic measuring line cleaning, a time interval can be freely defined in which the measuring lines are blown free by means of compressed air with a predefined blowing and recovery time. For both the operation of the controller and the display of the measured values, the HE 5422 MR is equipped with a three-digit 7-segment display, five keys and LEDs.
