精密压力表又称标准压力表,它具有很高的准确性,是一种高标准的量测组件。仪表的作用原理是基于被测介质的压力通过接头进入弹簧管时,在介质压力的作用下,弹簧管自由端产生位移,此位移通过拉杆传至齿轮传动机构放大,并带动指标逐将被测压力在表盘上指示出来。此仪表特采用由德国进口的高灵敏,低磨擦力的巴登管和刀锋状指针,能有效降低因为磨擦和读数误差而造成精度损失,从而提高仪表的准确率,此表广泛用于工矿企业、计量检定室、科研单位实验室的部门,作为压力计量标准使用来调校、校验、检定工业用一般压力表,同时也用于工业流程、科学实验环节中的高准确度要求的压力测量和监控。一般情况,用于测量对铜合金,不锈钢等无腐蚀性、非结晶、非凝固的各种介质的压力及真空。同时适用于检验一般压力表,作为压力测量的传递标准,也可用来精密测量对铜和不锈钢及其合金不起腐蚀作用的液体、气体和蒸汽的压力。可选全不锈钢精密压力表,因其对工作环境要求较低,抗腐蚀,耐高温(温度影响较小),耐压力脉冲可有效延长仪表的使用寿命;也可选用带调零装置的精密压力表,此型表可以避免零位漂移的错觉;还可选带镜面精密压力表,此型表读数直观,可以减少视觉引起的误差。可依客户要求订做,并可以做客户指定商标(*须提供商标使用授权书)。
Description
These test pressure gauges are manufactured to the very highest standards and are used to test Pressures of tanks, pipes fittings and in laboratories. The precision test pressure gauges have a high-grade measuring element. The pressure proportional elastic deformation of the Bourdon tube is transmitted through a low friction movement to the knife edge pointer. The gauges can be used with non aggressive gaseous or liquid, but not with highly viscous or crystallizing media. The measuring accuracy can be certified by the manufacturer in accordance with PION. 11 250 part 18 at additional cost. Features
*High reliability and durability by use of modular system
*Accuracy class 0.25~1.0
*Over range capability up to 1.3 times *Window of instrument glass
