2 产品介绍
TT-PWM60数字式温度传送器是设计用来测量变压器及其系统的温度的，并将结果转换成信号，用于远距离传输。
为了测量温度，要用双螺纹接头（图1/3）和锁紧螺母（图1/2）将温度传送器（图1/4）拧进温度计封套内（符合DIN42554）。

Description of the product
The digital temperature transmitter TT-PWM60 is designed for the measuring of temperatures on transformers and their systems and for the conversion of the results into signals for the purpose of remote transmission.
To measure the temperature the temperature transmitter (Fig. 1/4) is screwed into a thermometer pocket
(according to DIN 42554) by means of a double threaded union (Fig. 1/3)

温度传送器的温度由半导体元件（PTAT ）测量。传送器传输数字量输出信号，它的脉冲占空因素与绝对温度（脉宽调制）成正比。
测量值输出可以是模拟信号(0...1mA, 0...20mA 或 4...20mA) 也可选择RS485接口。仪表和电源通过一个插头（图1/6）连接到装置上。第2个电缆输出端（图1/1）将其它装置连接到RS485上。
其他设定和接线可以在装置的内部进行。为此，必须松开凹头螺丝，以打开壳盖（图1/5）。特定型号的参数就刻在铭牌上。图1/7）
传送器信号沿长长的导线传输时，大部分传送器（通常只有几个毫伏）的输出信号可能非常接近临界点。微弱的输出电压极易受到强供电设施、机器或高频传送器的电磁干扰，使得信号无法再用。
就是因为这个原因，今天，借助测量点上的传送器，传送器的模拟信号通常被转换成抗干扰的直流模拟信号（比如4...20mA ）。应当注意的是，数字信号要优于模拟信号传输，因为数字信号/噪音的传输距离要长得多。TT-PWM60配有抗干扰数字传送器，其数字量信号转换成抗干扰的直流模拟信号，还可选择使用RS485接口来传输。因此，TT-PWM60最适合长距离传输传送器信号。

安装
and a lock nut (Fig. 1/2). The temperature in the temperature transmitter is measured by a semiconductor element (PTAT). The transmitter transmits a digital output signal, the pulse duty factor of which is directly proportional to the absolute temperature (pulse-wide modulation).
The measurement output is provided by an analog signal
(0...20mA 20mA) and an RS485 interface which is available as an option. The instrument leads and the power supply are connected to the device by a plug (Fig. 1/6). A second cable outlet (Fig.1/1) is provided for the connection of additional devices to the RS485 interface.
Additional settings can be made and wiring provided inside the device. To do this, the lid of the housing (Fig. 1/5) must be opened by unscrewing the recessed head screws. The type-specific temperature transmitter data is shown on the name plate (Fig.1/7).
When the transmitter signal is transmitted along lengthy leads the output signals of most transmitters (often just millivolts) can be highly critical. The low output voltages can be interfered with to the point of unusability by electromagnetic interference from power installations, machines or high-frequency transmitters.
It is for this reason that analog transmitter signals are generally converted these days into relatively interference-immune current signals (e.g. 4...20mA) at the measuring point with the aid of transmitters. It should be noted that digital signal transmission is preferable to analog transmission because of its much better signal/noise distance. The TT-PWM60 comes with an interference-immune digital transmitter, the digital signal of which is converted to an interference-immune current signal and is optionally available via an RS485 interface. The TT-PWM60 is therefore ideally suitable for the transmission of transmitter signals along lengthy leads.
3 Installation
重要说明
必须严格遵循该说明中规定的操作和安装条件。
IMPORTANT
It is imperative that the installation and operating instructions specified in these Terms and Conditions of Operation and Installation are strictly complied with.
按照DIN42554标准，该温度传送器安装在一个温度计封套内。
安装步骤如下：
向温度计封套内灌2/3的油。如灌的油太多，温度传送器被拧进封套时油会溢出。
从温度传送器处松开双螺纹接头G1"（图1/3，扳手尺寸32毫米），确保整个过程密封圈未脱落。 将双螺纹接头拧到温度计封套内。
The temperature transmitter is designed for use in a thermometer pocket according to DIN 42554. Install as follows:
Fill the thermometer pocket to 2/3 with oil. If filled any higher the oil will spill over when the temperature transmitter is being screwed into place.
Unscrew the double threaded union G1" (Fig. 1/3; wrench size32 mm) from the temperature transmitter, making sure the seal does not drop out in the process. Screw the double threaded union into the thermometer pocket.
