Summary of the invention
The purpose of this utility model is the technical matters existed for prior art, provides a kind of formaldehyde Calibration Box, can realize the calibration of formaldehyde pick-up transducers by mass simultaneous, can improve its production efficiency, and structure be simple, safe and reliable.
In order to solve problem set forth above, the technical solution adopted in the utility model is:
A kind of formaldehyde Calibration Box, forms inclined-plane between the end face of this Calibration Box and a side, and this inclined-plane adopts transparent material and as visual window; Described side is at least installed a gland bonnet, its opposite flank is at least installed a fan; The inside of Calibration Box is at least provided with two pieces of location-plates, and formaldehyde pick-up transducers is stuck between two location-plates, and the inside of Calibration Box is also provided with the formaldehyde acquisition process circuit be connected with formaldehyde pick-up transducers;
Described formaldehyde pick-up transducers gathers the formaldehyde gas concentration of Calibration Box inside, and outputs it to formaldehyde acquisition process circuit; The formaldehyde gas concentration received is converted into magnitude of voltage by formaldehyde acquisition process circuit, and outputs it to outside human-computer interaction interface.
Adopt 48 pieces of location-plates vertically and bottom the inwall being set in parallel in Calibration Box on, 48 formaldehyde pick-up transducers and 3 formaldehyde acquisition process circuit are provided with at most in Calibration Box, 3 formaldehyde acquisition process circuit connect successively, and each formaldehyde acquisition process circuit connects 16 formaldehyde pick-up transducers respectively.
Angle between described inclined-plane and surface level is 30 ° ~ 60 °.
Described Calibration Box is rectangular box.
Described Calibration Box is arranged two gland bonnets and three fans.
Compared with prior art, the beneficial effects of the utility model are:
1, in the utility model, Calibration Box forms inclined-plane as visual window, be convenient to the installation of observation and formaldehyde pick-up transducers; The inwall of Calibration Box arranges location-plate, and for installing formaldehyde pick-up transducers, its structure is simple and be easy to realize; Be provided with at most 48 formaldehyde pick-up transducers and 3 formaldehyde acquisition process circuit in Calibration Box, namely can realize the calibration of formaldehyde pick-up transducers by mass simultaneous, its production efficiency can be improved.
2, Calibration Box PARA FORMALDEHYDE PRILLS(91,95) pick-up transducers is adopted to demarcate in the utility model, namely complete formaldehyde pick-up transducers in a sealed meter environment to demarcate, toxic gas (formaldehyde) can be prevented in timing signal contaminated environment and operating personnel, its structure is simple, safe and reliable.
