GB 4716 Point-Type Heat Detectors Closed Loop Chamber

GB 4716 point type heat detectors closed loop chamber is used to detect the reaction time of a standard oven. This oven is a closed loop wind tunnel, temperature sensors, wind turbine wheel, guiding device, heater, heating The main part of the slope of the temperature control system consisting of turbines, control cabinet, using computer control system for a wide range of the temperature sensitive motion detector alarm, the temperature sensitive response time tests.

GB4716 point-type heat detectors closed loop chamber is fully consistent with GB 4716, EN 54-5, ISO 7240-5 and other standards. This equipment taking into account the latest point type heat detectors latest product features, which makes the GB 4716 point type heat detectors with a wide range of closed-loop chambers very practical, not only can meet the technical specifications required by GB or both European and American standards, it can be widely applied to quality control unit, production companies, foreign companies and international inspection agencies and so on.

GB 4716 point-type heat detectors closed loop test chamber Technical requirements: a control duct airflow velocity in the testing process is always 0.8m / s (measured at 25 ℃), and can be respectively 0.2 / min, 1 heating rate 3,5,10,20,30 warming, measurement error is +2, response time measurement error + 1s. During the test to ensure that the probe accessory duct airflow from bottom and side walls of the impact, the probe heater is not subject to direct heat radiation.
