PORTABLE CALIBRATION MODULE FOR CALIBRATION AND INSPECTION OF SIGNALS OF COMBUSTIBLE GASES STM-30-50 Russian patent published in 2018 - IPC H01L29/00 G01L9/00 

FIELD: security systems.

SUBSTANCE: invention relates to industrial safety in control systems for contamination of hazardous industrial facilities. Essence of claimed technical solution lies in fact that easily removable portable calibration module comprises dismountable body with internal voltage supply lines to combustible gas alarm and milliammeter installed in circuit of analog output from said signaling device, while outer part of case is equipped with indicator of displaying milliammeter readings and connectors, one of which is designed to be connected to indicator sensor unit, and other connector is configured to be connected to signaling and signaling module.

EFFECT: technical result observed in implementation of claimed solution is creation of instrument that provides ability to calibrate and verify combustible gas detector STM-30-50 at place of installation, without dismantling, which increases reliability and quality of calibration and verification of signaling devices, operational reliability, facilitates control of working capacity and settings, reduces material costs for acquisition of calibration gas mixtures used in carrying out these works.
