客户希望在一个设备中获取切换能力，局部压力指示和4-20 mA输出信号。我们有产品要提供它们吗？

回答

是。DH，DHII或DH3具有高/低设定点，数字计量显示器和空气和兼容气体的4-20 mA全尺度输出信号。EDA，DPG-200，DPT和MDPC具有高/低设定点，数字计量显示器和4-20 mA全尺度输出信号，用于兼容的流体。

您的磁力仪不带校准证书，您是否有任何文档来满足这些需求？

回答

We have 3 options: (1) We can supply a Certificate of Conformance at no charge if you request that certificate at the time of order. The Certificate of conformance would state that each Magnehelic gauge is calibrated to meet the specifications stated on the spec sheet. (2) We offer a factory calibration “-FC” as an option that is a certificate of the standard calibration points at the time of manufacture, for a small fee. (3) We can also provide a NIST-traceable calibration for an extra charge per gage if that is required. To get the NIST-traceable calibration, you would simply add a “-NIST” to the end of your part number. NIST-traceable calibrations will come with the 6 point calibration certificate. We recommend “periodic calibration” for our Magnehelic, though we leave the specific time-frame up to the end user, since different organizations have different requirements (i.e. government groups often require more frequent calibrations.) If you choose to have the NIST traceable calib

我正在使用DH3 Digihelic差压控制器，用于我的应用程序。该指令表示“可以通过前面板上的复位键或外部复位开关重置警报”。对于第二种情况（由外部复位开关复位），您能让我知道如何做到吗？该指令没有提供任何相关的细节。提前致谢。

回答

Unfortunately, contrary to what was printed in the instruction manual, the DH3 does not have the ability for the alarm to be reset via an external reset switch, mainly due to the limited number of pins available in the electrical connector. This feature is only available in the DH and DHII series Digihelics.
