TAM-K-type wide-range air tritium monitors - China Institute for Radiation Protection -

TAM-K-type air tritium monitors the products produced by China Institute for Radiation Protection. [Introduction] TAM-K-type wide-range tritium monitor for tritium monitors were one continuous real-time online tritium glove box air. Its detector consists of an inner and outer volume of 2 liters each, can compensate for coaxial γ ionization chamber constitute compensation. Hollow cylindrical electrode detector for γ compensation chamber, outside the gas-flow measuring tritium silk wall ionization chamber. Host is a single-chip system 8031 ??as the core component, with automatic control, auto-zero, the data show a variety of parameters, data monitoring and processing, storage, alarm communications and other functions. Technical index ● measuring range: 100Bq / L --- 4.0 × 109Bq / L. Each range expanded multiple of 33.3 times, from the most to resist to the most high-end conversion time of less than 20s. ● Accuracy: relative error of less than 5%, the coefficient of variation of less than 2%. ● Response time: Adjustable, automatic adjustment. ● Working temperature: 0 ℃ to + 50 ℃, additional error is less than 2%. ● Operating Humidity: less than 95% Rh, no condensation, additional error is less than 10%. ● Storage capacity: 32K bytes, can store 5000 data. ● alarm threshold: any setting. ● Power supply: ~ 220V, the rectifier + 12V, the measurement ≤6W. ● Communication Interface: RS-485 standard interface, transfer rate 19200bps. ● Machine size: Detectors: φ200mm × 350mm (H); the second instrument 220mm × 120mm × 250mm can be installed separately. ● Total Weight: 20kg ● Working time: continuous operation all year round. ● Working protection: In the case of a sudden power failure, the data memory power-down protection battery, ensure that data is not lost. ● detectors: wire wall ionization chamber, the effective volume of 1.2 L / each ionization chamber. ● Clock: American DALLAS company DS12887日历时钟芯片, real-time recording the measurement time, the monthly timing error is less than 1 minute. [Features] has a high sensitivity, low memory effect of the advantages that can automatically switch across 8 ranges, each range expanded multiple of 33.3 times. From the resist to the most high-end conversion time of less than 20s. [Applications] applies high radon environment tritium CEMS.
