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.

該單位打算 a) 在潛在的爆炸性情況下清除前置放大器, b) 在前置放大器的電子設(shè)備可能變得太熱的情況下冷卻該單元。

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.?在爆炸環(huán)境中, 可以安全地使用Tyne氚監(jiān)測器, 并對凈化裝置進(jìn)行適應(yīng)性改造。這將允許使用干惰性氣體 (氮?dú)狻鍤饣蚝?, 通過前置放大器, 從而排除空氣, 從而消除了形成爆炸性混合物的機(jī)會。前置放大器可以很好地密封, 以保持前置放大器內(nèi)部的輕微正壓。如果在超過50°c 的環(huán)境中運(yùn)行, 則建議清除單元冷卻前置放大器。

特征

可安裝在手套箱外。
可以調(diào)整以控制前置放大器的流量或壓力。
