Level measurements - Import export

The optical level switches of this series are ideal for the detection of fluids with low DK value, such as lubrication oil or hydrocarbons. Optical level sensors detect the change of the refractive index at medium contact with the transparent tip from polyethersulphone (PES) or glass. The sensors with stainless steel housing and glass tip are also suited for the detection of aggressive media, such as solvents. Also available with Ex certification according to ATEX and IECEx.

EGE microwave filling level monitors monitor the filling level of fluids, powders and granulate with a low DK value and are particularly resistant to adhesion. The MFC sensors are also suited for separation layer detection. The sensitivity is adjustable. The sensors are based on a special variant of microwave frequency shift technology. EGE supplies the sensors in varying lengths up to 1000 mm. The stainless steel and PTFE sensor tip is suited for use in aggressive media.

The P-Log3021-MMC was specifically developed for applications demanding an increased memory capacity and high sampling rates. The measurement of the water level is carried out based on a piezoresistive pressure sensor and the measurement of the temperature is achieved by a high-precision measuring resistor. Its exceptionally high resolution and accuracy allow for water level and wave movements to be measured accurately to the very last millimetre.

P-Sense transducers for pressure and temperature can be used both in air and in water or other fluids. Devices come with analog, digital or switching output and can be configured for absolute pressure or gauge pressure measurements. Potential fields of application are water level monitoring or fluid level measurements, e. g. in bodies of water, sewage treatment plants, storage tanks etc. The p-Sense320 probe can be fitted with an RS485 interface instead of an analog output which can optionally be connected to a computer using a RS232 adapter. Connection and data transfer to a PC/notebook can established with the Windows terminal.

The models P-Log3020 PA (=absolute pressure) and P-Log3020 PR (=gauge pressure) are data loggers capable of measuring water level with an accuracy of a few millimeters and also water temperature. Highlights of these data loggers are their high resolution as well as large memory. They offer a high long-term stability and provide reliable measurements over many years without a battery change thanks to an optimised energy consumption.
