Document Type and Number:
Japanese Patent JP2909096
Kind Code:
B2
Abstract:
In a gas detection system for detecting the content of inflammable, explosive and/or toxic or other gases an arrangement is proposed according to which a central electronic evaluation system is connected to a plurality of measuring heads, which are installed at the points of measurement, by a single common two-wire line and each measuring head is provided, at its place of installation, with its own intelligence (microprocessor) for processing at least partly the values supplied by the sensor, each measuring head being equipped with at least two sensors of different types or measuring ranges and with an additional temperature sensor and each sensor having an identification which is indicative of the type and measuring range of the sensor and which is picked up by the measuring head. The electronic evaluation system and the measuring heads communicate with each other by bidirectional digital communication, after the measuring heads have been addressed, and the measuring head is supplied with current via the two-wire line.
