Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement, in particular to a wide-temperature dropping point photoelectric detection device. Background Technique

[0002] The wide-temperature dropping point photoelectric detection device is a device used to detect the dropping point of grease in a wide temperature range. The device includes a heating chamber that can precisely control the temperature, and the grease sample to be tested is placed therein. The temperature control system gradually increases the temperature according to the set program. As the temperature rises, the grease gradually softens and begins to drip. The photoelectric detection part usually consists of a light source and a photosensitive element. The light emitted by the light source irradiates the area where the sample is located. When the grease begins to drip, it will block or change the propagation path of the light. The photosensitive element can sensitively capture this change in the light signal. Once a sudden change in the light signal is detected, it means that the grease has reached the dropping point state. At this time, the relevant circuits and control systems will record the temperature at this time, and this temperature value is the dropping point temperature of the sample.

[0003] In the existing wide-temperature dropping point photoelectric detection device, the light emitted by the light source is relatively diffused during use, which is likely to lead to insufficient sensitivity in detecting the moment when the grease drips, resulting in low accuracy of the detection results.

The other ends of the L-shaped rods 206 are fixedly connected to form a mounting rack 207. The dust suction device 208 is fixedly installed at the bottom of the mounting rack 207. Electromagnets 209 are fixedly installed at the card slots 205 on both sides of the placement rack 201;

[0040] The setting of the arc-shaped groove 203 in the placement rack 201 provides a guarantee for the placement and fixation of the condenser sheet 204. The setting of the light-transmitting groove 202 can avoid blocking the light. The condenser sheet 204 plays a role in concentrating the light. The cooperation between the card slot 205 and the L-shaped rod 206 provides a guarantee for the sliding of the dust suction device 208. The dust suction device 208 can absorb dust. The cooperation between the electromagnet 209 and the L-shaped rod 206 provides kinetic energy for the sliding of the dust suction device 208;
