Ashcroft 45-2274-SD-02L-XAO-XU1-XEN-VAC/100# 数字卫生计
压力表有三种独立的供电模式，分别为电池供电，4至20 mA回路供电，以及12至36 V线路供电
线路供电单元为压力表，换能器，和继电器提供能源
仪器外部采用IP65外壳，保证了安全性
面板采用易于阅读的5个数字显示器
数码工业压力表完美的应用于制药和生物技术领域，终点精度为.25％。多功能压力表在化工，纸浆，造纸，废水和过滤过程中都得到广泛的应用，使用本地的4至20 mA输出和开关选项指示。开关的额定电压为125伏，0.5安培。因为本机是数字式的，则开关在量程范围内，具有无限的死区。并使得设定点在量程内具有卓越的灵活性。回路模式和线路模式的压力表的输出信号，能够远距离监控和控制被测信号，如控制室和机柜。压力表的测量范围为真空至20,000 psi。
0.25％的精度包括线性，滞后，重复性和端接
Operate with battery, 4 to 20 mA, or in- line 12 to 36 VDC
In-line powered unit acts as gauge, transducer, and switch
Intrinsically- safe IP65 case
Easy to read five digit display
Digital industrial gauge is perfect for pharmaceutical and biotech with its .25% terminal point accuracy. The multi-functionality of the gauge is great for chemical, pulp and paper, wastewater, and filtration processes, using local indication with the 4 to 20 mA output and switching options. Switch is rated for 125 VAC, 0.5 amp. Because the unit is digital, the switching option has unlimited deadband throughout the range of the gauge, and gives the unit superior set point flexability. Loop and in-line gauges have output signals that enable monitoring and control from remote areas such as control rooms or enclosures. Gauge range is vacuum to 20,000 psi.
Quarter percent accuracy includes linearity, hysteresis, repeatability, and termina
