铂丝缠绕电阻式温度探测器(RTD)采用非常精细的高纯度的铂线缠绕在陶瓷芯上，采用玻璃涂层密封。
Platinum wire wound Resistance Temperature Detectors (RTD) construction consists of very fine high purity Platinum wire wound onto a ceramic core and then hermetically sealed with a glassed coating.
为了确定探测器周围环境中的背景分布，一个空的密封烧杯计算以同样的方式，在相同的几何形状的样品。
In order to determine the background distribution in the environment around the detector, an empty sealed beaker was counted in the same manner and in the same geometry as the samples.
探头为声光探测器，使用密封的空气室和压力传感器。
The head is a photo-acoustic detector using a closed air-cell and a pressure transducer.
