                    • submersible probes | level probes

                    • BD|SENSORS offers a wide range of submersible probes designed for the measurement of fill levels of fluid or paste-like media or for levels of water and waste-water. The sensors are based on hydrostatic pressure, i.e. the fill level is found by measuring pressure.

                      The submersible probes are available with many types of enclosure materials, pressure sensors and diameters and will thus in their standard version already offer perfect solutions to predominant installation conditions. 
                      The detachable submersible probes are noteworthy. These designs allow very simple detachment of probe and cable, requiring no tools. This is a decisive advantage during maintenance or servicing, since only part of the submersible probe will require attention, not the entire installation.

                      • with stainless steel sensor LMP 308 | LMP 808
                      • with ceramics sensor LMK 358 | LMK 808 | LMK 858

                      The range also includes other designs such as submersible probes with integrated overvoltage protection, temperature sensors or data loggers, also types communicating via RS 485 interface or HART® protocol.


                    • Detachable submersible probes

                    • Our detachable submersible probes boast easy maintenance, debugging and repairs. Sensor heads are in this case separable from the instrument without touching the remaining cabling. You may now examine, clean or replace the probe head and then simply screw it on again. Simple, fast and at the drop of a hat.

                        • Evaluation devices and displays

                        • In order to correctly interpret analogue signals, display and evaluation devices are indispensable.

                          Besides the classic version with display and analogue outputs (PA430, ASM430), BD|SENSORS offers with the process display of CIT-series an evaluation device that can be combined with our pressure measuring devices and hydrostatic submersible probes and is furthermore also suitable for acquiring for example temperature and potentiometer signals.

                        • Data logger

                        • The data logger can record up to 2 million measurement values with a maximum measuring rate of 1 Hz in internal memory (8 MB).

                          By connecting a USB stick, the capacity can be enlarged to several GB. The LoogySoft software (CIT 600 / CIT 650 ) or DAQ-Manager (CIT 700 / CIT 750) helps the user displaying (table, graphic), saving, evaluating and exporting the recorded data.

                      • CALIBRATIONS

                        • Since the BD|SENSORS GmbH calibration laboratory is accredited to the DIN EN ISO/IEC 17025 Standard it is authorized to perform calibrations according to DakkS [German Accreditation Body] and issue calibration certificates that are nationally and internationally recognized based on the multi-lateral ILAC agreement. Calibrations are carried out compliant with DKD-R 6-1.

                          The accreditation includes relative and absolute pressures up to 800 bar with measurement uncertainties down to 1.1 ppm. This measurement uncertainty allows calibrations of all pressure measuring instruments such as electronic pressure measuring instruments (measurement transducers, transmitters and pressure sensors), pressure switches and digital pressure gauges with accuracies ≤ 0.1% FSO.

                          The calibration laboratory uses highly accurate reference standards (piston manometer) and standard instruments (accurate electrical pressure measuring instruments) that, together with our many years of experience, allow us to offer competent calibrations delivered on time.

                                  • Plant and equipment used on ships and yachts are exposed to the harshest of climatic conditions, to rough environments and extremely high mechanical stress. BD|SENSORS pressure and fill level measuring instruments will remain reliable and durable for many years under such conditions of stress. The many certifications for shipping worldwide document that the functionality and design of our equipment is eminently suited for deployment on ships.

                                    Examples of applications include:
                                    • Fill level measurements in tanks on container ships containing a diversity of media(potable water, ballast/industrial and waste water, fuels, liquid chemicals and more)
                                    • Control of anti-heeling systems, measurements of draught

                                  • Chemistry / Petrochemistry

                                  • Chemical processes make very high demands on electronic pressure measuring instruments and hydrostatic fill level probes in two respects:

                                    • processes may be complex with high dynamic pressures and fast changing temperatures
                                    • the media are diverse and may be chemically aggressive, explosive, toxic, abrasive and sometimes also dirty and viscous.

                                    Add to this top safety requirements, especially in explosion hazardous plant and equipment and the absolute demand for top operational reliability.

                                  • water/waste water/recycling

                                    The acquisition of fill and gauge height is a central requirement in this field. BD|SENSORS here deploys the highly reliable method of hydrostatic fill level measurement. In practice this is implemented in different variations -  be it in the form of level probes for surface and ground water applications, submersible probes for wastewater treatment plants and storm water overflow tanks, or down to fill level probes for tank farms and in container construction. 
                                    In addition to probes of any imaginable type required for water processing, we also offer solutions designed for aggressive media such as acids and lyes.


                                    The combination of a diversity of materials for enclosures with sensors made of metal and ceramics is a perfect basis for innovative customer solutions. BD|SENSORS in this way ensures that the hydrostatic water and fill level concept will remain superior to any other method of measurement, both in terms of technology and price and in terms of accuracy, service life, reliability, simple fitment and commissioning.

                                  • Oil and Gas industry

                                  • Scientists these days believe that the natural resources of oil and gas are not quite as finite as thus far assumed. These resources are likely to remain available considerably longer than hitherto predicted.
                                    This is the reason why BD|SENSORS is one of only a few global companies that recognized a need for the development of accurate and robust instruments for the measurement of pressures in the field of oil and gas production - including traditional onshore and offshore drilling for and extraction of oil and also fracking.

                                    • Measuring pressures in pumps, drilling heads and sludge recirculation lines
