该装置采用红外传感器作为机电转换装置,通过远距离传输,由智能化仪表显示被测液面的高度,并可实现高低位报警。该装置是用于室外“0”区危险环境的本安型仪表,它由红外线机电变送器、智能显示器(一)、装在控制室内的电源安全栅和智能化仪表(二)配套,构成本质安全型防爆系统(已取得防爆合格证)。其性能特点为:①采用钢丝传动,避免了使用钢带传动时的扭曲、旋转或卡死等弊端。②采用
The device uses infrared sensors as mechanical and electrical conversion device, through the long-distance transmission, by the intelligent instrument shows the measured level of the liquid, and can achieve high and low alarm. The device is an intrinsically safe instrument for outdoor dangerous environment “0” area, which consists of infrared electromechanical transmitters, intelligent display (A), installed in the control room power supply safety barrier and intelligent instrument (B), constitute Intrinsically safe explosion-proof system (explosion-proof certification has been made). Its performance characteristics: ① using steel wire transmission, to avoid the use of steel belt drive distortion, rotation or stuck and other drawbacks. ② adopted
