causing imbalance of the bridge. The sensor signal is amplified, detected, and fed to a measuring instrument showing a 9 and a comma device 7. The command device is computed with such an oupajo.vi that with small, safe, H2 concentrations in the control system, and also the warning signals are not issued. In the event of terror, the permissible content of the commander will give the appropriate signals. The setting of the comaid device is made to issue passwords at 2.5 vol. % H2 and. The appearance in the ambient atmosphere, and c, consistently, and in the controlled volume of the explosive –project shell of CH4 will lead to an increase in the output signal of the bridge measurement circuit and will cause the comaid device to generate a sigtal in the presence of H2.

The signals for the CHR to change the content of CH4 are provided to the NPA concentrates HZ, which is determined by a certain ratio of the sensitivity of the sensor to P2 and CH4. In order for the device to work, it should be equal to 7.2.

This is ensured by the choice of the temperature mode of the sensing elements, as well as the combination of the parameters of the sensory parameters 11 Tel. ulemept and block, as well as the size1, by bringing together an insulating sheath with a thermal conductivity coefficient that is close to the heat conductivity coefficient B – B, reducing the channel diameter reduces the effect of the convective component on the signals from Il2 and SRC.

Relationship The coefficients of TNC conductor H2 to CH4 are 5.11-4.11, with a changed temperature from 330 to 480 ° K. Temperature regime; The elements in the proposed device are limited to 370–400 ° K danazop to exclude the possibility of an H2I sensitive element on the surface of a catalytic effect on the surface of Tatiola.

Experiment: it is established that the diameter of the i.v. of the shear is irradiated, as well as the thickness of the insulating sleeve, which is obtained from the pressurized asbestos, and the diameter of the channel in the brass block equal to
