摘要： The present invention relates to a self-cleaning probe for performing optical measurements in a gas or liquid flow. The probe comprises a measuring cell defining a passage for the gas or liquid to be measured to pass through, and includes minimum a first and second optical interface on opposite sides of the passage. The probe further comprises at least one optical light source emitting an optical signal and a detector for receiving an optical signal having propagated partly or fully through the gas or liquid flow from the first to the second interface. All optical interfaces are acoustically coupled to one acoustic transducer connected to a power source, adapted to produce vibrations in the frequency range of 5 kHz-1 MHz, the vibrations being substantially perpendicular to the plane of the interfaces and the acoustic energy exceeding the cavitation threshold in a liquid, so as to remove deposits on the optical interfaces.

摘要： The present invention refers to an online monitoring system for the gravitational separation of oil emulsions, more specifically, a monitoring system for the properties related to the emulsions, such as the drop size distribution (DSD) and the water content (WC), simultaneously, in pressurized and heated systems at high pressures and temperatures, respectively, using near-infrared region (NIR) spectroscopy coupled with optical microscopy.
The online monitoring system is innovative as it overcomes the current need of the oil industry to remove aliquots from emulsified systems under high pressure and temperature, preferably up to 70 bar (7 MPa) and 150° C., respectively, for determination of the properties of emulsions, which causes disturbances and affects the physicochemical characteristics of emulsions. Thus, the invention makes it possible to infer about the stability of the emulsions under real operating conditions by monitoring the gravitational settling of water drops dispersed in a continuous phase of oil.

摘要： Disclosed is a method for measuring the absorbance of light of a substance in a solution in a measuring cell (23; 223′), said method comprising the steps of: transmitting (S1) a first light beam (27; 27′) from a light source (25; 25′) towards a beam splitter (29; 29′); dividing (S3) the first light beam (27; 27′) into a signal light ray (31; 31′) and a reference light ray (33; 33′) by the beam splitter (29; 29′); modulating (S5) the signal light ray (31; 31′); modulating the reference light ray (33; 33′); providing (S9) the measuring cell (23; 23′) such that the signal light ray (31; 31′) passes through the measuring cell; detecting (S11) a signal in a detector (39; 39′), which signal is the combined signal intensity of the signal light ray (31; 31′) and the reference light ray (33; 33′) detected by the detector (39; 39′); performing synchronous detection (S15) of the detected signal in order to reconstruct the intensities of the signal light ray (31; 31′) and the reference light ray (33; 33′) from the combined signal detected by the detector (39; 39′), said synchronous detection being based on the modulation performed to the signal light ray and the reference light ray. Disclosed also is a measuring device for carrying out said method.

摘要： A remote sampling sensor for determining characteristics of a sample includes measurement optics and an insertion probe. The measurement optics are configured to emit light and detect returned light. The insertion probe includes a chamber, the chamber being configured to permit the sample to enter the chamber, an insertion tip at a distal end of the insertion probe, and a retro-reflective optic adjacent the insertion tip. The retro-reflective optic is configured to return the light from the measurement optics through the chamber to the measurement optics. The insertion probe is configured to be remotely located from the measurement optics.

摘要： The present invention is directed toward the early detection of harmful algal blooms. The system employs the ability of whole cell non-contact micro Raman spectroscopy to detect cell pigmentation in such a way that distinct patterns or fingerprints can be assembled. Light field microscopy will provide a fundamentally innovative increase in image and sample volume. Furthermore, darkfield microscopy is employed to capture high-resolution, color images of the detected plankton to increase the accuracy of species identification and classification. Together, this new instrument will provide a powerful yet elegantly simple solution to detection of HAB cells and characterization of environmental conditions.

摘要： Rolling bearings include a plurality of rolling bodies which during operation roll on raceways. In order to reduce friction during rolling, it is customary to supply the rolling bearings with a lubricant. However, the quality of the lubricant can deteriorate during operation due to long-term stress, aging, or thermal influences, or get lost in gaps etc. The objective addressed by the invention is that of providing a sensor device, which can be operated in a functionally reliable manner. This objective is achieved by a sensor device for monitoring the state of a lubricant in a lubricant chamber, including a transmitter platform, wherein on the transmitter platform, a plurality of diode devices are arranged, having a measurement window device, wherein the measurement window device is arranged between a measuring chamber and the lubricant chamber, having a receiving device, wherein at least one of the diode devices comprises a die and a plastic dome. The plastic dome and the die are connected by way of a contact surface, wherein the contact surface is arranged on an upper side of the die.
