Embodiment
Online chromascope is by photoelectric detective box 1 and show that controlling cabinet 2 two parts forms, as shown in Figure 1, photoelectric detective box 1 is installed near the field instrument case of detected solution, shows that control cabinet 2 is installed on the panel board of pulpit, and both connect with lead 3.Photoelectric detective box 1 is a flat rectangular parallelepiped, as shown in Figure 2, central interior is established a cell 18, light source 16 and monochromator 17 are fixed on the left side of cell 18, photoelectric conversion component 5 is fixed on the outside of cell 18 the right dividing plates, the right side of photoelectric conversion component 5 connects an electronics amplifying unit 6, is connected to lead 7 on the electronics amplifying unit 6.
Show that controlling cabinet 2 is made up of digital display unit, temperature control unit, voltage regulation unit, connection terminal and metal shell.Electronics amplifying unit, voltage regulation unit and temperature control unit are fixed in the metal shell, and digital display unit also is fixed in the metal shell, but manifest digital display screen, and connection terminal is fixed on the outside of metal shell.
As shown in Figure 3, cell 18 is rustless steel containers of a column type, and housing 19 is fixed on the interior negative of photoelectric detective box 1, and top is the cover plate of photoelectric detective box 1 housing, separates with metal partion (metp) 4 and other element all around.The left side of cell 18 is light source 16 and monochromator 17, and the right is a photoelectric conversion component 5, and the centre separates with sealing gasket 15.Feed tube 9 and drain pipe 8 are arranged at the top of cell, so that the part solution in the production procedure can flow to and flow out, there are windowpane 20 and 21 in two ends, so that monochromatic luminous energy injects and penetrates.During use, solution flows to and drain pipe 8 flows out from feed tube 9, and the monochromatic light that produces from light source 16 and monochromator 17 injects from the windowpane 20 on the left side, and the windowpane 21 from the right behind the solution in the irradiation cell penetrates.Because solution to the absorption of light, penetrates light intensity from windowpane and just weakens to some extent, the colourity difference of solution is also different from the light intensity that the windowpane of cell penetrates.
As shown in Figure 3, the structure of photoelectric conversion component 5 is semi-cylindrical closed containers, and its shell is fixed on the metal partion (metp) 4 with screw 6, and is tightly adjacent with cell.A circular hole is opened in the left side in the photoelectric conversion component, so that the luminous energy that penetrates from cell enters photoelectric conversion component, adorns a photoelectric cell 13 on the circular hole, adorns a Temperature Detector 10 on the photoelectric cell 13, and a well heater 11 is established on Temperature Detector 10 right sides.After the irradiate light that penetrates from cell is to the photoelectric cell, photoelectric cell is according to light intensity, send proportional electric signal, this signal is transferred to the electronics amplifying unit by the lead on the photoelectric cell 25, finally by showing that the digital display unit in the control cabinet 2 demonstrates the chromatic value of solution.Because photoelectric cell is relatively more responsive to the variation of environment temperature and humidity, in airtight photoelectric conversion component, put into drying agent, the photronic ambient humidity of may command＜60%, variation of ambient temperature＜± 0.1 by Temperature Detector 10, well heater 11 and the temperature control unit may command photoelectric cell 13 in showing control cabinet 2 ℃.Like this, can be converted to proportional, electromotive force stably with guaranteeing to be radiated at light intensity on the photoelectric cell.Owing to the solution in the cell that is shone by monochromatic light flows, the electric signal that obtains from photoelectric conversion component also is continuous, variation, thereby the on-line continuous that has realized solution colourity detects.
