4. keyboard, display circuit: wherein keyboard is used for carrying out the selection of fibrous material to be measured, the parameter settings such as setting value of temperature; Display circuit adopts LCD to be used for the regain of display fibers material, the real-time detected value of humidity and the real time temperature value in the baking oven, can also show the real-time change curve of humidity, temperature;
5. sound light alarming circuit, when recognizing that by the humidity that detects air in the baking oven fibrous material to be measured has reached drying regime, system sends signal with the mode of sound and optical flare, points out the experimenter to take by weighing the operation of dry weight.
6. the interface circuit of host computer communication: detected value can be sent to upper PC and store or print, be beneficial to network management and resource sharing.
Compared with prior art, the utility model has following beneficial effect:
1. simplify the experimental implementation process: this testing apparatus be " the drying state of understanding fiber by the humidity of air in the test oven " thus finish the test of fiber regain, can solve the problem of existing Oven Method complex operation from test philosophy.When existing Oven Method is tested the fibrous material regain, in order to confirm that material has reached dry mass, behind the drying certain hour, (be generally 1 hour) at regular intervals (10 minutes) carry out claiming in the case or outside the case weighing apparatus to material, and the title when twice title weighing apparatus of poor quality is lower than certain proportion (0.5%) before and after taking sees that quality is the dry mass of material.This process can reach 10 times and repeat to claim the weighing apparatus operation.After adopting the utility model, can will claim the weighing apparatus process to shorten to for the last time.
2. shortening experimental period: the each title weighing apparatus operation when existing Oven Method is tested the fibrous material regain all will influence the subenvironment humiture in the baking oven, thereby make experimental period prolong.After adopting the utility model,, can shorten experimental period, enhance productivity owing to claiming the weighing apparatus number of times to reduce the fluctuation that has reduced ambient temperature and humidity in the baking oven.
3. reduce the additional experiments error: existing Oven Method is requisite introducing manual operation error in each title weighing apparatus.After adopting the utility model, make human intervention reduce owing to claiming the weighing apparatus number of times to reduce, error reduces.
4. reduction power consumption: this testing apparatus adopts computing machine that test data is calculated, handled, and cooperates sound and light alarm to notify the fiber oven-dried condition at once, is beneficial to energy-conservation.Owing to shortened the experiment criteria thus the drying time, also can reduce power consumption greatly simultaneously, meet energy conservation and environment protection.
5. be easy to promote the use of: the utility model can be used by transformation on existing homemade Y802 series constant temperature oven.Enterprise's only use expense input (about 500 yuan) seldom can be finished the upgrading of baking oven.
