PT-400 Heavy Duty Pressure Transducers from Automation Products Group, Inc. have received ATEX and IECEx certification, rated EX II 1G Ex ia IIB T4 Ga, for use in hazardous locations throughout the world. With all stainless steel laser welded construction, these pressure transducers deliver reliable high pressure sensing in harsh environments that are prone to high shock and vibration and high pressure spikes throughout a wide range of operating temperatures. A larger size (5.3 in. tall by 1.5 in. wide) PT-400 pressure transducer, ideal for oil and gas applications, is also now available.
PT-400 pressure transmitters provide a minimum of 10 million operating cycles with high accuracy up to ±0.1% F.S. (B.F.S.L.), in operating temperatures from -40 to 180°F. They cover pressures ranging from 0 up to 20,000 psi, along with high burst pressure to 3x full scale (limited by the process connection) and overpressure to 2x full scale for in-process reliability. The PT-400 is designed for demanding applications in oil drilling, water and wastewater industries as well as for general use in other industries.
PT-400压力传感器提供标准的4-20mA，0-5 VDC和0-10 VDC输出，具有1/4-18 NPTM工艺连接。即使使用坚固的不锈钢外壳，用户仍然可以访问零并调整跨度以校准特定的应用程序要求。它们坚固的结构和性能属性使它们非常适合需要放大输出信号的静态和动态压力测量。许多选项，包括延长的温度补偿，更高的准确性评级和替代过程配件等。
发射器也cCSAus注册使用in hazardous locations throughout North America. Units with 0-5 VDC, 0-10 VDC and 4-20 mA outputs are rated for Class I, Div. 2, Groups C and D, and Class I, Zone 2, Group IIB hazardous locations. In addition, units with 4-20 mA output are rated for cCSAus certified for use in Class I, Div. 1, Groups C and D, and Class I, Zone 0, Group IIB hazardous locations. The ATEX and IECEx certification applies only to 4-20ma units.
