一、结构与用途 Sturcture and Use | | | 精密压力表主要用来校验工业用普通压力表,也可用于精密测量对铜合金和合金结构等无腐蚀性、非结晶、非凝固的各种介质的压力。仪表由测量系统、指示部分和表壳等组成。仪表有较好的密封性并设有检封装置,能保护其内部测量机构免受机械损伤和污秽浸入; 仪表的作用原理是基于弹性元件形变。在被测介质的压力作用下,迫使弹簧之未端产生相应弹性形变-位移,借助于拉杆经齿轮转动机构的传动并予放人,由固定于齿轮轴上的指针逐将被测值在刻度盘上指示出来。 Precision pressure meter is to use check the industrial normal pressure meter,and can be measure some medium pressure like have no corruption for copper, no crystal, no-concretion. The meter composed by test system,note parts and body. The meter has a better airproof feature,and have seaI check system, and can protect the detect depart be dirt or machine broken . | | | 二、技术参数 Technique parameter | | | 名 称 Name | 型 号 Model | 准确等级 Precision grade | 使用环境条件 Work environment | 温度影响 Temperature influence | 连接螺纹 Joint screw | 弹簧管材料 Spring pipe material | 测量范围(MPa) Test range | 精密压力表 Precision pressure meter | YB-150 YB-150A | 0.4/0.25 | 5℃-40℃,相对湿度不大于80%,且震动和压力源的波动应对仪表的精确度读数无影响 5℃-40℃,the humid is Not pass 80%,and the vibration and pressure source is not effect the meter precision | 使用温度如偏离(20±3)℃(A型)或(20±2)℃(B型)时,则须考虑温度附加误差(0.4%10℃) If the temperature departure(20±3)℃(A style)or(20±2)℃(B style),must to conceder the temperatue append error.(0.4%10℃) | M20×1.5 | 锡磷青铜铬钒钢 Tin-phoshor-bronze-chrome-vanadium steel | -0.1~0 0~0.1 0~0.16 0~0.25 0~0.4 0~0.6 0~1 0~1.6 0~2.5 0~4 0~6 0~10 0~25 0~40 0~60 | 轴向带边精密压力表 Axis direction pressure meter with the margin | YB-150ZT | 不锈钢精密压力表 Stainless precision pressure meter | YB-150BH | | 注:1.括号内型表示可选,可参照型表示图 | 2.量程除MPa,可以Psi/bar,mmHg…… | Note:1.In the bracket (the model should be selected),can be refer to the table of model | 2.The measuring range except MPa,also to use Psi/bar,mmHg…… | 三、型号表示及外形尺寸 Model express and figure dimension | | | | 代号 code name | 说明 Illusion | YB | 精密压力表 Precision pressure | 150 | 表盘直径 150mm Table diameter 150mm | A | 表示0.4级 Express 0.4 grade | B | 表示0.25级带调零装置 Note 0.25 grade with the back zero set | H | 全不锈钢 Full stainless steel | ZT | 轴向带边 Axis and with border | | 注:如有其它要求须我厂技术确认澄清后可定制。 | Note:If you need other need,please clarify by engineer and to order. | |
