美国SETRA西特 www.setra.com
Setra Systems, Inc. 成立于1967 年，以电容技术闻名于世界。由Setra 的创始人Dr. Y.T. Li 和 Dr. S.Y. Lee 发明的革命性的高精度可变电容变换原理，已取得了30 多项专利，并作为Setra 压力、加速度、称重产品的技术核心，广泛应用于各种尖端设备中。作为美国阿波罗登月计划中精密传感器产品供应商之一，Setra微差 压传感器在全球范围内享有盛誉。在经过40多年的研究、开发和持续改进，Setra 产品广泛应用于HVAC/R，工业过程控制、测量测试、环境参数测量和半导体超纯测量等领域。其在华业务由丹纳赫西特传感工业控制（天津）有限公司全权负责。
从1982年开始，Setra（西特）将其高超的电容技术应用于电子天平，设计出极具竞争力的电子天平和各种称重系统。除了可以选择不同量程和精度的天平之外，您还可以选择带有记数功能、通讯功能和打印功能的天平，构成称重/计数系统解决方案。
产品包括：实验室分析天平，精密电子天平，计数秤重系统，油漆程，气瓶称等。
 
Setra 公司总部设在美国马萨诸塞州的Boxborough，在那里有140 名员工从事开发设计、生产管理；在中国的工厂位于天津西青微电子园区，有18600m2 厂房和250 名员工。Setra 公司通过了ISO9001 ：2000 认证，我们将坚持持续质量改进、按时交货、完善的客户服务为客户提供优质的产品，满意的服务。

丹纳赫西特传感工业控制（天津）有限公司拥有众多传感器品牌，生产并销售Setra西特（压力传感器、温湿度传感器和变送器、电流传感器、压力计等）、Anderson-Negele安德森耐格（卫生型温度、压力、液位、流量传感器）、Joslyn Clark强士林克拉克（真空接触器、FM认证消防泵控制器）、WEST（温度控制解决方案）、必测（固体物料测量）、NAMCO（核级限位开关）、Nyliner（塑料轴承和紧固件）等多个世界知名品牌。

美国SETRA西特精密电子天平是美国Setra Systems,Inc.公司将其拥有的国际专利技术陶瓷镀金电容传感技术在精密称重领域中成功应用的结果。1987年美国SETRA西特公司总裁 Dr.S.Y.Lee因此项发明，而荣获ISWM（International society for weighing and measurement)颁发的技术杰出奖。美国SETRA西特精密电子天平系列是为了满足用户对高精度、低价格和功能的要求而设计的，它们均采用了陶瓷电容称重传感器，由于陶瓷电容称重传感器需要的部件很少，所以使天平的结构得以精简并保持很低的外形。陶瓷材料优良的物理性能保证了美国SETRA西特系列电子天平具有很高的稳定性，很小的迟滞。
