LL3液氮指示器/控制器的主要用途是测量和控制开口或封闭容器内的液氮高度,工作压强高达20Psi。敏感元件探头可放在距指示器数百英尺远的地方而不会损失测量精度。其工作原理是测量液体底部与顶部之间的压差。敏感元件探头由一个灵敏的压力传
The main purpose of the LL3 liquid nitrogen indicator / controller is to measure and control the height of liquid nitrogen in open or closed vessels up to 20 psi. Sensing element probes can be placed hundreds of feet away from the indicator without loss of measurement accuracy. It works by measuring the pressure difference between the bottom and top of the liquid. Sensitive element probe by a sensitive pressure transmission
