DEVICE FOR CONTROLLING DEPLETION OF REGENERATIVE CARTRIDGE OF SELF-CONTAINED BREATHING APPARATUS WITH CHEMICALLY BOUND OXYGEN

摘要

A device for controlling the depletion of the regenerative cartridge of the self-contained breathing apparatus with the chemically bound oxygen contains the thermal detector and the power supply for the indicator appliance. The latter consists of the differential amplifier, the high-pass filter, the integrator, Schmidt trigger, and microprocessor that are interconnected in an electrical circuit. The power supply represents one or several accumulators and the spark-protecting elements with stand-by conductors and the electronic elements of the electrical circuits embedded in compound. Microprocessor is equipped with the autonomous battery.
