Grünewald SMALL-Ex Series Level Measuring For Open Tanks With Pressure Equalization

The level measuring instrument is used for level measuring of fluid mediums in tanks or receptacles without inner pressure. The measuring instrument also can be equipped with integrated temperature measuring. They are designed for use in filled systems with fluid medium.  The gauge accuracy depends on the temperature of the medium and the viscosity. These parameters are each compensated.t the bottom end of the instrument with or without tube, a piezo-resistive pressure transducer is mounted. Using this construction, any tank or receptacle of any size or depth can be checked and measured. The level measuring can be carried out either by a probe tube, which is inserted into the tank or receptacle from the top or from the side or as screw-in instrument without probe tube to measure at the bottom of the tank or receptacle. Customized  to the application, variants are available with a straight probe tube as well as a 75 ° or 90 ° bent probe tube.A variety of mechanical connections are available, such as different threads or flange.he measuring instrument can optional be equipped with an illuminated LCD-display. For more comfortable use the measuring instrument can be designed with a stepped sensor. The sensor is in a separate housing and is connected with a cable to the evaluting unit which can be equipped with a display. Level measuring instruments with a flange connection can be designed with a display turned 90° to the front.If the level measuring instrument is equipped with an integrated temperature measuring, both values can be displayed alternately in a time interval where both measurement signals are continuously transmitted to the control system.Marking:Certifications:       Env.
