HD6993
柴油机车和轨道汽车罐仪表
Application
Model HD6993 gauges are designed for extended life and accurate readings of fuel levels in tanks aboard diesel locomotives and rail cars.
General Information & Features
Model HD6993 gauges are for side or angle mounting. Tank drawings and strapping tables should be submitted with all inquiries.
这些仪表具有易于阅读的 4 "[100mm] 分数表盘, 或以加仑为选项校准, 精度为±2.5%。对每个仪表进行特殊的校准和功能检查。包括一个特殊的近距离小齿轮齿轮, 以实现最小齿轮的夹紧。
为许多部件选择了不锈钢材料, 以确保可靠的服务和最大的强度。硬质镀镍齿轮和轴承最大限度地减少了振动引起的磨损, 特殊结构减少了必要的维护, 以防止在装运、安装和服务过程中更改校准。
可选的支撑衣领可用于具有异常长的支撑和支撑管道延伸到罐内的仪表。
