Difmanometra with a class of accuracy 1 are delivered in coordination with manufacturer.
Devices have adjustment of range of measurement which allows to recustomize them on any limit nominal pressure differences given for this modification.
Sensitive element is the rezinotkanevy membrane.
Material of flanges — cast iron, details of measuring knot — steel 45 and Steel 12X18H10T , alloy 36NHTYu.
Under the influence of a difference of pressure on a sensitive element of the measuring block there is an effort which is transmitted through system of levers and drafts to the pneumoconverter gate.
As a result the gap between a nozzle and the gate changes that leads to change of pressure in a pneumatic amplifier chamber.
This pressure comes on an exit of the device and to the feedback bellow valve which creates the moment counterbalancing the moment from pressure difference.
Food air consumption in the set mode to 3 l/min.
Devices are intended for work at a temperature of air of 5 — 50 °C and relative humidity to 80%.
Execution is ordinary, export, tropical.Technical characteristics of difmanometr of the DM-P type
