Abstract
A monitoring device for portable breathing apparatuses having a manometer by means of which the pressure in the pressure container of the breathing apparatus is detected, and having a transmitter by means of which a signal corresponding to the pressure is transmitted at regular intervals. The transmitter also has a signal generating device which generates an identification signal which is characteristic of the transmitter. The pressure signal and identification signal are received and tested by a receiver. If the identification signal matches an identification comparison signal stored in the receiving device, the measured pressure value is displayed on a display device.
