The main features of the construction of gas analytical leak detection systems are noted, from the point of view of the sensitive element and the test substance (gas) used in the leak tightness control. It is shown that when checking the tightness of functioning systems, the standard leak detection equipment is of little use because it is impossible, in most cases, to use the specific test gases necessary for its operation. The use of solid-state gas analytical sensors for the construction of leak detection systems for operating process equipment is proposed. It is shown that one of the most suitable is the optical chemical sensor because of its low sensitivity to the humidity of the carrier gas, which, in such a process of leak detection, is atmospheric air. The properties of the proposed sensor are investigated, which are most important when used in leak detection systems. These parameters are the dynamic characteristics of the sensor, which are determined depending on the operating temperature and pressure of the sensor. The obtained data showed the prospects of using the investigated sensor and also allowed to outline ways of improving and optimizing its design.
