WDL-31 photoelectric thermometer Product description
WDL-31 photoelectric thermometer is a non-contact infrared temperature measuring instrument, which uses the balance comparison method to measure the radiant energy of the object to determine the temperature value. It is suitable for quickly measuring the surface temperature of stationary or moving objects in the industrial production process, such as iron melting in metallurgy, machinery industry, thermoforming processing, heat treatment, glass product industry, textile industry fabric heat setting, rubber industry rotating, roller surface , Temperature measurement of semiconductor material single crystal, polycrystalline connection system, etc. Output a unified linear signal, which can be used in conjunction with various recorders, regulators and electronic computers for automatic recording and adjustment control.
Because the photoelectric thermometer has a fast reaction time, it should usually be used in conjunction with the XWZK speed automatic balance recording bottom, which can keep the reaction time still less than 1 second. Specifications

Product selection information
The Liandan cable is composed of a two-core shielded wire for the output of Xincheng and a three-core wire for the transmitter power supply. The end with the connecting plug is connected to the detector, the plug wiring is shown in the figure
The water-cooling jacket is a shell with a water-cooled interlayer. It is used when the ambient temperature is higher than 35°C or in places with strong radiation and dust to protect the detector from working normally.
The protective lens tube is a tubular long simple, which is installed on the water cooling jacket to protect the objective lens from pollution or damage by smoke, dust, water vapor, etc. in the environment.
The mounting bracket is composed of a mounting base, a gimbal, bracket, and fastening screws. The bracket is fixed and installed on the gimbal with screws. The detector does not have a water cooling jacket. The bottom of the detector is inserted into the plate pin when using it. On the pallet, the bottom of the fastening screw is installed between the bracket and the gimbal and fixed with screws. Then fix the upper and lower inserts on the bottom of the detector with fastening screws before use.
