校准压力变送器中,要求必须准确测量输入输出值并求取误差率。
CA700 不但可以高精度测量压力和电流的输入输出值,还内置了校准步骤,只要按照既定步骤操作,就可以顺利完成精确的校准作业。
在压力开关测试中打开触点时,可以测量关闭时的压力、死区和电阻值。
由于内置了校准步骤,只要按照既定步骤操作,就可以顺利完成精确的校准作业。
调整电空转换器的输入输出时,可以将电流上调或下调25/50/75/100%,逐步检查并确认。
CA700拥有4-20mA信号步进发生功能,也可以高精度测量发生压力,因此可以用于高可靠性测试。
CA700可以从仪器仪表的外部电压发生源(配电器)吸入(SINK)设定好的电流,作为变送器模拟器进行环路测试。
输出4-20mA电流时,其输出精度高达读数的0.015%。
CA700可以一边给变送器供电(DC24V),一边测量DCmA信号。
包括归零点确认等在内,可以精确测量DCmA信号,精度可达读数的0.015%。另外,由于内置了250Ω的通信电阻(支持HART/BRAIN通信),在连接手持终端时无须外接250Ω的电阻。
CA700可以输出DC1-5V、4-20mA的模拟仪表信号,输出精度高达读数的0.015%,可以用于仪表环路测试和机器动作和指令确认。
有线性扫描和步进扫描两种发生模式可供选择(扫描时间可以设为15/30/45/60秒)。

压力校准器CA700产品介绍
FieldMate is PC and tablet based software for adjusting, setting and managing devices. It systematizes a series of work from field calibration of a pressure / differential pressure transmitter to report generation in combination with the Pressure Calibrator CA700. They achieve speedy, highly efficient field calibration by offering calculation of relative error, pass/fail determination and report generation as well as automatic recording of device information and calibration data. Recorded calibration data can be registered in FieldMate' s database (device maintenance information) along with other maintenance information. CA700 and FieldMate, "Smart Calibration" significantly reduce the man-hours for calibration.
