? Description
    Model 700.01 is particularly intended for the monitoring of differential pressures even in the case of high working pressures in gas and air preparation and supply systems.
    Model 700.02, the version with a separation diaphragm, is suitable for liquid media and therefore also for water treatment and supply systems.
    This piston-type differential pressure gauge offers special advantages due to its compact modular design. For instance an on-the-spot replacement of measuring system and case of indication is possible in retrospect and the
    Reed contacts can also be retrofitted and adjusted locally.

    A front surface mounting flange may be retrofitted on model 700.01.
    Although these models have a high overload capacity either side up to the maximum working pressure, the weight of the standard versions, i.e. approx. 220 g in the case of model 700.01 and approx. 500 g in the case of model 700.02, is extremely low. Therefore, these gauges provide an economical and flexible solution to your measuring task.
    This compact design with a measuring system of stainless steel enables an optimal price/performance ratio.

   Design and operating principle
    Pressure p1 and p2 are given in the j and i measuring medium chambers separated by magnetic piston under pressure or magnetic piston and separation diaphragm for Model 700.02.
    The difference in pressure causes axial movement (measuring travel) of the piston supported by a measuring range spring.

    A magnetic ring mounted on the instrument pointer follows the magnet‘s movement in the piston so that each piston position is appropriated to a defined pointer position.
    This design ensures complete mechanical separation of the measuring system and the case and eliminates external leakage.
    The stream of volume from the measuring chamber to the measuring chamber is minimised by the constructive design and will not intefere with the process (only for Model 700.01).
    For applications where liquids or dirty and heavily contaminated media are to be measured the version with a separation diaphragm Model 700.02, is suitable (no volume flow from j and i media chamber).

   Installation
