称重传感器

品牌：美国 OSI

 

型号：CTF&CTFB

 

类型：电流传感器

 

 

产品描述DESCRIPTION

CTF和CTFB电流传感器为closedloop，是专为交流、直流、脉冲和变频驱动器设计的高精度电子传感器。输出与输入成正比，输出波形与“通过窗口”电流相同。

The CTF and CTFB current sensors are closedloop, highly-precise electronic sensors designed for ac, dc, pulse and variable-frequency drives. The output is directly proportional to the input and the output waveform is identical to the “through-window”current.

CTF和CTFB提供0.1%的线性。坚固的结构和较低的温度灵敏度确保在广泛的温度范围内进行可靠的测量。型号在外壳或电路板布置中提供。

使用CTA800-*进行仪器电源和输出信号调节。

The CTF and CTFB provide 0.1% linearity. Rugged construction and reduced temperature sensitivity ensure reliable measurements over a wide range of temperatures.

Models are provided in enclosures or circuit board arrangement.

Use CTA800-* for instrument power source and output signal conditioning.

安装说明/INSTALLATION INSTRUCTIONS

1.只能由合格的电工进行安装！

2.在进行任何电气连接之前，确保电气服务已断开。

3.支路保护按国家和地方规范要求设置检查机构的报告。

4.按要求布线，并按照本表和装置上的接线图固定到端子上。

5.传感器适合安装在600Vac线路上。

6.为防止与带电电路接触，当安装在裸母线上时，要求传感器安装在需要使用工具进入的外壳中。当安装在绝缘电缆上时不需要第二个外壳的电缆。

1. Installation should be performed by qualifi ed electricians only!

2. Make sure electrical service is disconnected before making any electrical connections.

3. Branch circuit protection is required to be provided in accordance with the National and Local codes of the inspection authority.

4. Route wires as required and secure to terminals per connection diagram on this sheet and on the unit.

5. Transducers are suitable for installation on 600Vac lines.

6. To prevent contact with live circuits, when installed on a bare bus bar, the transducer is required to be mounted in an enclosure that requires the use of a tool for access. When installed on an insulated cable this second enclosure is not required.

 

 

操作说明/OPERATING INSTRUCTIONS

1.本装置适用于海拔2000米以下的室内使用。

2.根据安装类别（过电压）II，污染等级2的瞬态过电压。

3.如果需要清洁外表面，则应断电所有供应服务（两个测量和仪表电源电路），并用软刷刷洗或用低压空气吹扫。使用适当的眼部保护。不适合清洗软管。

4.最高相对湿度80%，温度最高31ºC，线性下降至50% 40℃时的相对湿度。

5.最大工作温度范围为-20°C至60°C。

1. This unit is intended for indoor use at altitudes up to 2000 meters.

2. Transient overvoltages according to Installation Category (overvoltage) II, Pollution Degree 2.

3. If cleaning of the exterior surface is necessary, de-energize all services of supply (both measuring and instrument power circuits) and brush with a soft brush or blow off with low-pressure air. Use appropriate eye protection. Not suitable for hose-down cleaning.

4. Maximum relative humidity 80 percent for temperatures up to 31ºC decreasing linearly to 50 percent relative humidity at 40ºC.

5. Maximum operating temperature range is -20°C to 60°C.
