电器连接方法（ GDM3009 接插件）
使用与校准
1、安装与接线（见图）
各种类型的压力变送器均可直接接在检测系统的接口上，标准螺纹为M20 × 1.5 阳螺纹。
24VDC 电源通过屏蔽电缆给变送器供电（请注意防水），“＋”接24VDC 正极，“－”输出4 － 20mA 电流给取样电阻
2、使用
变送器接线如图所示，联线正确即可使用。
Electrical connetion (GDM3009 plug-in package)
No.1 Using and calibration
All kinds of pressure tran***itter will be connected directly to test system,with standard male thread M20×1.5.
Tran***itter is supplied Power 24VDC by shielding cable(water-proof),with anode 24VDC connected and 4-20mA for resistance.
No.2 Application
As is shown in wiring diapram, using in correct connection.
注意事项
1、变送器是使用带膜片的传感器，切勿用任何物体接触膜片，以免造成***性损伤而损坏传感器。在介质温度太高(＞ 80℃)时，应加装散热器以保证测量精度．
2、安装时请***人员用***工具进行安装、
3、变关器的校准应在加电5分钟后进行.并注意当时的环境温度．变送器不要随意开盖以免受潮，且变送器壳体及导线屏蔽层应牢固接地避免干扰及雷击。
4、电源应当使用带有隔离的仪表电源避免工业电源串扰，特别慎用开关电源容易自激损坏变送器。电源及信号输出应采用屏蔽电缆传输并压紧进线螺母，以保证气密性。依***标准变送器每6个月应校准一次。
5、外配雷击管只能抗3A 冲击电流，应并联在＋、- 极之间。如果打穿，请更换该无件。
备注
用户选型时请告知使用环境和安装方式，如对型号命名不清楚时可用文字说明，接口螺纹可根据要求单独设计。
Note:
No.1 Tran***itter is the sensor with diaphragm ease note that anything is prohibited to touch diaphragm,protecting against destroying for ever.Add the radiator when temperature is over 80℃.
No.2 Installation under the instruction of skilled worker.
No.3 Calibrate the tran***itter should be five minutes later when power is supplied and be aware of environment temperature. It can not be opened case so as to keep se and leads will be connected to earth ***oiding disturbing and lightning strike.
No.4 Using gauge power with isolation to ***oid industrial power disturbing,not using switch power at discretion,which can destroy tram***itter.Power and output signal will shield cable tran***itting and press nuts firmly. According to national standard ,it will be calibrated once six months
No.5 lighting-strike pipe can stand 3A current between anode and cathode .If it is broken,please instead .
Remark
Please inform working environment and mounting on type selection. We could help select model and design the thread for clients.
