希而科火热销售WIKA BWX 系列 压力开关

WIKA公司是德国乃至大的生产压力和温度测量仪表及设备的专业厂家之一，总部位于德国法兰克福克林根堡，子公司遍布全球七十多个国家。

带有波登管，膜片或膜盒测量系统的一般压力表，绝大压表和差压表已经接受无数次检验。 这些仪表的测量范围从0...2.5mbar至0...7000bar，精度等级可达0.1%并且可以配备机械的或电子的附件，也可以结合不同结构的化学密封来实现不同的测量目的。

DescriptionThese high-quality pressure switches have been developed especially for safety-critical applications. The high quality of the products and manufacturing in accordance with ISO 9001 ensure reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. All wetted materials are from stainless steel as a standard.In order to ensure as flexible operation as possible, the pressure switches are fitted with microswitches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled microswitches with gold-plated contacts can be selected.Depending on the application, the appropriate variant for the contact version and the electrical connection can be selected; e.g. adjustable dead band instead of fixed dead band is often a feature necessary for control processes.For applications with special requirements on the wetted parts, a version with Monel is available.By using a Bourdon tube measuring system, the model BWX pressure switch is extremely robust and guarantees optimal operating characteristics and the highest measuring performances, with repeatability lower than 0.5 % of span.For safety applications, the pressure switch is optionally available in a SIL 2-qualified or a SIL 3-qualified version
