Used to measure the pressure of liquids and gases if it is not possible for the measured medium to penetrate into the gauge or transmitter measuring device.
This need arises where they occur:
The solution consists in using a separating membrane and an inert liquid, that transfers pressure to the gauge or transducer measuring device.
We produce and repair many types of separators, different types of flanges and dimensions.
Selection of membrane size
Small measuring range, greater operating temperature differences, higher accuracy requirements, longer capillary length, low damping requirement - all these are factors that lead to a larger diaphragm demand.
Filling the separators with the working fluid
The filling is carried out in a vacuum because the filled compartment has to be completely degassed. Similarly, the working fluid must be free of dissolved gases before filling. With regard to the conditions in which the system is to operate, we use the following working fluids:
Ordering information
The accurate and reliable function of the diaphragm separator system depends primarily on the choice of the type of separator and its size.It is also important to set the initial parameters, including adjusting the stiffness of the diaphragm and determining the optimum amount of working fluid. In the order it is advisable to specify the following parameters:Type and size of the required separator; Range of measured pressure and required measurement accuracy; The temperature of the measured substance (permanently, short-term in measurement, short-term without measurement); Ambient temperature; Working position (horizontal, vertical, oblique, top / bottom diaphragm axis); Type of liquid to be measured, resp. With any warning about its aggressive effects; The type of barometer or converter to be used with the separator, including the specification of its attachment dimension.
Application of protective foils
PTFE films increase the resistance of the stainless steel membrane against the effects of some aggressive chemicals.
Against the abrasive effect of solid particles entrained by the flow of measured fluid, the membrane is protected by a layer of soft rubber.
