The unit is intended a) to purge the preamplifier in potentially explosive situations, and b) to cool the unit in situations where the electronics of the preamplifier may get too hot.
该单位打算 a) 在潜在的爆炸性情况下清除前置放大器, b) 在前置放大器的电子设备可能变得太热的情况下冷却该单元。
Tyne tritium monitors can be safely used in explosive environments provided adaptation is made for a purging unit. This will permit access of a dry inert gas (nitrogen, argon or helium), to flow through the preamplifier thereby excluding air, and hence eliminating the opportunity for the formation of explosive mixtures. The preamplifier can be sealed sufficiently well to maintain a slight positive pressure inside the preamplifier. The purging unit is also recommended to cool the preamplifier if it operates in an environment of more than 50°C. 在爆炸环境中, 可以安全地使用Tyne氚监测器, 并对净化装置进行适应性改造。这将允许使用干惰性气体 (氮气、氩气或氦), 通过前置放大器, 从而排除空气, 从而消除了形成爆炸性混合物的机会。前置放大器可以很好地密封, 以保持前置放大器内部的轻微正压。如果在超过50°c 的环境中运行, 则建议清除单元冷却前置放大器。
