O instrumento mede: Qualidade do Ar - VOC
O Sensor mede: VOC

O sensor de gás misto AO-RL2 / A (VOC) com display de LED mede a qualidade do ar na faixa de 0 ... 100 referente ao gás de calibração. Para transformação posterior, ele fornece um 0-10 V linear, o sinal de saída 0-20 mA, 4-20 mA e um contato. A qualidade do ar ambiente normal pode ser definida para o padrão de calibração manual no dispositivo (ajuste do ponto zero). O sensor de qualidade do ar executa um procedimento de calibração automática em intervalos regulares, portanto, desvios de longo prazo e deterioração da operação podem ser totalmente eliminados.

Initial operation After switch-on of the device follows a self-test and the tempering, which takes ca. 1 h depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value.
Automatic calibration The automatic re-calibration of the output signal is started in the interval of 4 weeks and can be disabled. The device must be supply within this interval at least 10 minutes with fresh air.
Manual calibration The manual calibration of the output signal to 1V (zero point) will be started by pushing the button on the circuit board (push ca. 5 s until LED is blinking). Before this it is to ensure a non-stop operating of min. 2 h on air quality which is defined as normal. After successful calibration the LED will be deactivated.
Installation on-wall or on flush-mounted box
Approvals CE-conformity, EAC, RoHS
