20150362429 | METHOD AND ARRANGEMENT IN CONNECTION WITH SEPARATE SAMPLE TAKEN FROM PROCESS LIQUID - A method and an arrangement are disclosed in connection with a measurement arrangement of optical parameters of a separate sample taken from a process liquid, in which method a sample is taken from the process liquid. The sample can be arranged into a sample vessel provided with at least one measurement window, and optical parameters of the sample in the sample vessel are measured through the measurement window. In the sample in the sample vessel, a flow is produced which can be used to mitigate (e.g., prevent) the measurement window surface in contact with the sample from getting dirty. A back-and-forth flow can be produced in the sample residing in the sample vessel by means of pressure variation focused on the sample, and the back-and-forth flow can be focused on the surface of the optical measurement window. | 12-17-2015 |
20140268115 | METHOD FOR MEASURING REFRACTIVE INDEX, AND REFRACTOMETER - An exemplary method for measuring a refractive index of a substance being measured through an optical window, includes arranging the optical window in contact with the substance being measured, directing light to the interface of the optical window and substance being measured, where part of the light is absorbed by the substance being measured and part of it is reflected from the substance being measured to form an image, in which the location of the boundary of light and dark areas expresses a critical angle of the total reflection dependent on the refractive index of the substance being measured, and examining the formed image. Light is directed on a first structure and to desired angles on an interface between the optical window and substance being measured. Light reflected from the interface of the optical window and substance being measured is directed on a second structure. | 09-18-2014 |
20130239678 | MEASURING SENSOR - A measuring sensor includes an elongated shell part, manufactured from a synthetic gemstone material or ceramic material, is provided with a first end and a second end, the first end being arranged in a process medium to be measured. A housing structure is manufactured from a material softer than the synthetic gemstone material or the ceramic material and arranged to surround the measuring electronics. The second end of the elongated shell part is arranged to be supported against the housing structure. The elongated shell part is fastened to the housing structure by a connecting piece manufactured from a material having a hardness property between hardness properties of the material of manufacture of the elongated shell part and the material of manufacture of the housing structure. | 09-19-2013 |
20130057675 | METHOD AND ARRANGEMENT FOR MEASURING FLOW RATE OF OPTICALLY NON-HOMOGENEOUS MATERIAL - A method and arrangement are disclosed for measuring a flow rate of optically non-homogeneous material in a process pipe. The non-homogeneous material can be illuminated through a window. Images are taken with a camera, through a window, of illuminated non-homogeneous material. Correlation between temporally successive images determines travel performed by the non-homogeneous material in the process pipe between capture of temporally successive images. Velocity of the non-homogeneous material is determined by the time difference between the successive images and the travel. | 03-07-2013 |
20120128029 | MEASURING SENSOR FOR TEMPERATURE MEASUREMENT - The invention relates to a measuring sensor for measuring temperature in a chemical process, the measuring sensor comprising a measuring element supported on the frame of the measuring sensor and arranged in thermal contact with the process being measured, and measuring conductors connected to the measuring element for directing a measuring signal onward. The frame of the measuring sensor is made of mineral material. | 05-24-2012 |
20120093192 | METHOD AND MEASURING SENSOR FOR TEMPERATURE MEASUREMENT - A method and measuring sensor are disclosed for measuring temperature, the method including arranging a measuring element of the sensor into thermal contact with a process being measured, and directing a measuring signal received from the measuring element onward by measuring conductors connected to the measuring element. Close to the measuring element, terminal areas are established which are arranged in unrestricted thermal contact with the process being measured, and the measuring conductors are connected to the measuring element through the terminal areas. | 04-19-2012 |
20110075141 | STRUCTURE OF MEASUREMENT WINDOW - A measurement window structure is disclosed for an optical process measurement device. The measurement window structure can include a measurement window made of an optical material and having a measurement surface that is arranged to be placed into a process solution, a sealing surface formed to a frame structure of the optical process measurement device and facing the process solution, the measurement window made of an optical material being arranged to press against the sealing surface, and an attaching device or mechanism for pressing the measurement window made of an optical material against the sealing surface and for attaching it to the frame structure. The sealing surface formed to the frame structure can be a rotationally symmetrical surface and the surface pressing against the sealing surface formed to the frame structure of the measurement window made of an optical material can be a rotationally symmetrical surface. | 03-31-2011 |
20100025374 | METHOD FOR MEASURING THE ACTIVE KOH CONCENTRATION IN A KOH ETCHING PROCESS - The invention relates to a method for in-line measuring the active KOH concentration in a KOH etching process in which process silicon hydroxide is produced by a reduction reaction according to the formula: 2K | 02-04-2010 |
20080227215 | Method and arrangement of measuring acidity for other chemical or physical property of a gas - A method and an arrangement of measuring acidity or other chemical or physical property of a gas. The invention comprises a membrane having optical indicator molecules bound to a microporous matrix arranged to be placed into contact with the gas to be measured, the optical indicator molecules changing their colour in response to the acidity or other chemical or physical property of the gas, a light source, and a detector. The light source is arranged to emit and direct light to the membrane, the light being transmitted through the membrane, whereby a part of the light is absorbed into the optical indicator molecules, and the rest of the light emitted is guided to the detector, where it is measured. | 09-18-2008 |
