Omówiono budowę i funkcje układu pomiarowego robota górniczego przeznaczonego do pracy w strefie zagrożonej wybuchem. Opisano zasadę działania poszczególnych rodzajów czujników zastosowanych do detekcji gazów trujących i wybuchowych.

In the paper, build and functions of the measuring system of the mining robot for working in explosive hazardous zones were described. Moreover the principle of operations of the applied sensors for detection of explosive and toxic gases were discussed.

Pressure Sensitive Mats as Safety Devices in Danger Zones

Dąbrowski S., Brański Z.

International Journal of Occupational Safety and Ergonomics

1998

Vol. 4, No. 4

Developing prototypes of pressure sensitive mats and testing their practical application were the aims of this study. Two contact plate mats were designed and constructed: rubber-rubber (R) and metal-metal (M). A recipe for rubber mixes and the production technology were prepared. Two laboratory test stands for measuring the actuating force, response time, static pressure resistance, and the durability of the mats were constructed. Computer software was written to control the operation of those test stands. Methods of testing pressure sensitive mats were based on PrDIN 31 006 (Deutsches Institut fur Normung [DIN], 1990) and EN 1760-1 (Comite Europeen de Normalisation [CEN], 1997). Both prototypes of contact plate mats were tested under laboratory and industrial conditions. The test results proved that the design was correct, the setup requirements were fulfilled, and the mats were efficient and reliable in the industrial environment.
