使用前检测
Pre-use inspection
在运输或仓储过程中，可能使SF6-气体密度继电器/远传密度继电器变冷或变热。当温度不等于参考温度(20℃)时指针会动。这种现象是正常的，因为温度补偿系统在工作。
During transportation or warehousing, SF6- gas density monitor/ remote gas density monitor may become cold or hot. When the temperature is not equal to reference temperature (20℃), the pointer will move, which shows the temperature compensation system is working.
为确定SF6-气体密度继电器/远传密度继电器与周围温度是否适应,必须在温度20±2℃环境下,恒温至少 2小时.指针才能指示到允许的误差范围内。
In order to determine whether SF6- gas density monitor /remote gas density monitor adapts to ambient temperature, the temperature of 20±2℃ must be maintained for at least 2 hours so that the pointer can work within the allowable error range.
投诉/更换/修理
Complaint/replacement/repair
售后服务时请给出生产编号和产品型号,生产编号印在表盘上,产品型号印在标牌上。
At customer service, please provide with the production number and product model. The production number is printed on the dial, while the product model is printed on the nameplate.
SF6-气体密度继电器/远传密度继电器必须长时间恒温才能达到温度补偿作用(至少两小时) 。
偿作用(至少两小时) 。
SF6- gas density monitor/ remote gas density monitor must be kept in constant temperature for a long time (at least two hours) so as to achieve temperature compensation.
只有厂家可以进行维修,不允许开仪表,否则会使显示和开关点产生误差。
No one other than the manufacturer is allowed to disassemble the instrument for fear that any error may occur to the display and switch point.
使用和维护
Use and maintenance
密度继电器/远传密度继电器应垂直安装，用在室外的密度继电器/远传密度继电器应避免阳光直射到仪表上，好在仪表上加装防护罩。
Gas density monitor/remote gas density monitor shall be installed upright. For a gas density monitor used outdoors, direct exposure to sunlight is not allowed, and it is advisable to use a shield.
密度继电器/远传密度继电器安装部位应能较真实地反映设备内气体的温度。
Gas density monitor/remote gas density monitor shall be erected at a proper position to reflect the temperature of gas in relevant equipment.
用肥皂水浸湿的擦布清洁仪表，要清洁接线盒或插头时要先把电源断开，再接通电源前确保所有部件不潮湿。
Clean the instrument with a wiping cloth soaked in soap water. Cut off the power supply before cleaning the terminal box or plugs. Make sure that all components are dry before turning on the power again.
安装
Installation
A．机械接口
Mechanical interface
一般仪表常用的技术性规范这里也使用 (如:En837-2),旋转安装时所用的力不允许直接作用到表壳或接线盒上,而是通过合适的工具作用到扳手面上.
Technical codes (e.g., En837-2) applicable to ordinary instrumentation also apply here. The force applied for rotation installation shall not directly act upon the instrument housing or terminal box but act upon the wrenching face through a suitable tool.
数据处理：
温度：Temperature = ( Temperature High | Temperature Low)/100 ℃
例：Temperature High=0xF6；Temperature Low=0x05
Temperature = 0xF605/100 = -25.55 ℃
压力：Pressure = ( Pressure High | Pressure Low)/1000 MPa
例：Pressure High = 0x12，Pressure Low = 0x34
Pressure = 0x1234/10000 = 0.4660 MPa
密度：Density = ( Density High | Density Low)/1000 MPa
例：Density High=0x56；Density Low=0x78
Density = 0x5678/10000 = 2.2136MPa
返回的温度、压力、密度数据为2字节有符号整数。
密度以对应20℃下的压力P20表示，单位MPa.
压力和密度用压力表示，若转化为相对压力，减去当地大气压。
