Notes:
1. Sensing resistance in air R
0
is measured under controlled ambient conditions, i.e. synthetic air at 23
?5?C and 50 ? 10% RH for RED sensor and synthetic air at 23 ?5?C and ≤ 5% RH for OX sensor.
Sampling test.
2. Sensitivity factor is defined as Rs in air divided by Rs at 60 ppm CO. Test conditions are 23 ? 5?C and
50 ? 10% RH. Indicative values only. Sampling test.
3. Sensitivity factor is defined as Rs at 0.25 ppm NO
2
, divided by Rs in air. Test conditions are 23 ? 5?C
and ≤ 5% RH . Indicative values only. Sampling test.
IMPORTANT PRECAUTIONS:
Read the following instructions carefully before using the MiCS-4514 described here to avoid erroneous
readings and to prevent the device from permanent damage.
? The sensor must be reflow soldered in a neutral atmosphere, without soldering flux vapours.
? The sensor must not be exposed to high concentrations of organic solvents, silicone vapours or
cigarette-smoke in order to avoid poisoning the sensitive layer.
? Heater voltage above the specified maximum rating will destroy the sensor due to overheating.
? This sensor is to be placed in a filtered package that protects it against water and dust projections.
? SGX sensortech strongly recommends using ESD protection equipment to handle the sensor.
附注：
1. 空气中的感应电阻R
0
是在受控的环境条件下测量的，即合成空气在23
RED传感器为?5?C和50?10%相对湿度，OX传感器为23?5?C和≤5%相对湿度的合成空气。
抽样试验。
2. 敏感系数定义为空气中的Rs除以60 ppm CO时的Rs。试验条件为23?5℃和
相对湿度为50?10%仅为指示性数值。抽样试验。
3. 灵敏度因子定义为0.25 ppm NO时的Rs
2
，除以空气中的Rs。测试条件为23?5℃
且相对湿度≤5%。仅为指示性数值。抽样试验。
重要的预防措施:
在使用这里描述的MiCS-4514之前，请仔细阅读以下说明，以避免错误的
读数，并防止设备的yong久性损坏。
?传感器必须在中性气氛中回流焊接，无助焊剂蒸汽。
?传感器不能暴露在高浓度的有机溶剂、硅蒸气或
香烟烟雾，以避免中毒的敏感层。
?加热器电压超过规定的zui大额定值将由于过热而损坏传感器。
?该传感器被放置在一个过滤包中，以防止水和灰尘的喷射。
?SGX sensortech强烈建议使用静电防护设备来处理传感器。
