INTRODUCTION1.1 Safety InformationThis manual contains information that must be observed in the interest of your own safety and to avoid damage to assets. Please read this manual before installing and commissioning the device and keep the manual in an accessible location for all users.To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance operation at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.1.2 Hardware FeaturesThe IWTT range of Wireless Temperature Transmitters has been designed to measure the Temperature of the medium connected and transmit the value to one of the IWR range of receivers where the value can be outputted as either a 4-20mA or 1-5Vdc signal.The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be linked to an IWTT transmitter.The IWTT temperature transmitter works on the licence-free 2.4 GHz band.Ranges of up to 500m are possible using the standard transmitter and receiver unit with the optional 3dBi antenna giving a range of up to 750m.The transmitter is powered by a 3.6V lithium cell and care must be taken to insert the battery in the correct polarity.2. UNPACKINGThe instrument should be carefully inspected for signs of damage which may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.3. PRODUCT IDENTIFICATION LABELThe unit delivered should be carefully inspected to ensure it is suitable for the application required. Detailed information on the product is included in the identification label and the user manual.Please ensure in particular, that the temperature range of the IWTT is suitable for the intended application and that the IWTT unit will not be subjected to temperatures and/or temperatures greater than those specified in this manual.4. INSTALLING/CHANGING THE BATTERYA Lithium 3.6V battery is included inside the IWTT transmitter. The battery may be changed at any time but the correct polarity must be observed at all times! After the battery has been changed, the unit should be switched on using SW3 pushbutton and then SW1 should be pushed for 5s.This is to ensure the battery life count is reset correctly when a new battery is installed.The internal LED will flash 5 times to indicate this procedure has been carried out successfully.The battery life is determined by the rate the transmitter sends the Temperature value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s.Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.5. SETTING UP THE IWTT WIRELESS TEMPERATURE TRANSMITTERThe IWTT instrument is shipped in a default configuration which allows the unit to connect with any default IWR receiver unit and transmit the measured temperature every10s simply by switching the unit on using SW3 on the internal circuit board.If a different update rate is required, or a different network frequency channel is required these parameters can be selected using DIP Switch 1 as detailed below:Switches 1, 2, 3 & 4 select the RF Network the IWTT will transmit on. The defaultnetwork for both the IWTT transmitter and IWR receiver is network 1.RF NETWORK 1 2 3 41 0 0 0 02 0 0 0 13 0 0 1 04 0 0 1 15 0 1 0 06 0 1 0 17 0 1 1 08 0 1 1 19 1 0 0 010 1 0 0 111 1 0 1 012 1 0 1 113 1 1 0 014 1 1 0 115 1 1 1 016 1 1 1 1Switches 5, 6 & 7 select the Transmission rate of the unit.

This is used with the 5 channel receiver unit (IWR-5) to select which Temperature transmitter is linked to which 4-20mA or 1-5Vdc output channel.Tx Channel Number 8 9 101 0 0 02 0 0 13 0 1 04 0 1 15 1 0 0The IWTT transmitter is now set up and ready to be used. Install the unit into the pipework as required and switch the unit ON using SW3. Pushbutton switch SW1 can be pushed to force the unit to transmit its current temperature and LED 1 will flash twice if the transmission has been received and acknowledged by an IWR receiver unit.If the unit has transmitted successfully the 4-20mA or 1-5Vdc output of the connected receiver unit will output a value reflecting the temperature level being measured.6. TROUBLE-SHOOTINGGUIDEProblem encountered Possible CausesLED1 doesn’t flash when pushbutton SW1 is pressed Unit not switched on, switch on using SW3. Battery not installed correctly.Battery needs replacing.LED1 only flashes once when SW1 is pressed IWR receiver not switched on.IWR receiver not set up for the same RF network.IWR receiver not within range of transmitter.If IWR-1 receiver is used, ensure that the transmitter is set to Tx Channel 1Output from IWR receiver isn’t equivalent to the Temperature being monitored IWR receiver set up incorrectly, see IWR user manual for further details.Check that the green external LED on the receiver is flashing when the transmitter pushbutton is pressed as receiver may be out of range.7.

指示仪表、记录仪表,调节器等能够与电源串联在输出回路,输出电流正比于温度的变化,但独立于电源的变化,其应用原理如下图所示:NHR-XTRM温度远传监测仪自热电阻传感器的测量信号通过前置放大器放大,然后被比较输入电路(选择高温信号)或选点输入电路选中某一路信号,该信号通过电流(V/I)转换单元将放大器的输出电压变为4-20A恒定电流输出,原理方框图如下图所示:七、仪表使用说明开机后需预热10分钟,仪表的安装应该尽量靠近测量点,这样可以充分利用二线制的如下优点:1.高的抗干扰能力,因为信号是在高电平情况下传送,达到抑止噪声和干扰的作用。
2.简单的布线,即仪表从现场控制室采用双绞导线连接就可以了,降低了布线的成本。
输入采用热电阻时,为了避免测量误差,传感器的引线电阻必须保证一定的数值,这里对于每也可以取任何截面积的导线,但引线总电阻必须确保为0.35Ω。

山东派瑞光电科技有限公司开发了无线测温系统。
它是工业的神经,它延长我们的视线,它十分接近隐患点。
由此,我们可以提前感知,采取措施,降低避免事故。
电气设备的触点在长期运行过程中,因老化、松动或污染易造成间隙或接触电阻增大,在通流时引起持续发热,严重时将造成设备烧损甚至引发更大的事故。
近年来,类似的事故已发生多起,已造成火灾和大面积的停电事故。
开关柜触头的温度很难实时监测,这是因为开关柜空间有限,但柜内元件较多,且高压带电元件大多裸露,常规的温度测量方法无法使用。
无线测温系统已成为测温领域的趋势。
一、产品应用具体应用在电气设备的各种触点、连接点,如开关触点、电缆接头、母线联接点、发电机和变压器引接线接头、电动机接线盒接头等,通过分布式安装在各个测温点上的传感器及时掌控易发热点的温度变化,在事故隐患产生时提前预警,避免事故的发生。
无线测温装置的应用和原理
无线测温装置的应用和原理前言:无线测温系统是一种无线测量、安装简便的温度测量系统。
它采用无线通讯技术进行高压隔离和信号传输,利用其固有的绝缘性和抗电磁场干扰性能,解决高压开关柜内触点运行温度不易监测的难题。
适用于各种类型的高压设备的温度在线监测,具有可靠的高压隔离、抗强电场、磁场干扰及良好的热稳定等特性。
10kV高压柜是电力系统中不可或缺的部分,其安全运行是用户负荷的重要保证。
高压柜的特点是负荷电流较大、容易发热,需要定期测温。
从结构形式上看10kV高压柜分为旋转刀闸式和小车式两种,小车式高压柜由于触头完全密封,在柜外无法观察测温,因此巡视人员只能通过对柜测温来间接推算内部是否发热、温度的传导损耗导致精度十分低,而且无法观察细微的变化,不满足安全运行的要求。
无线测温装置系统通过即时监测开关触头等发热点温度,可发现异常发热故障苗头,从而防止故障的发生,并且通过温度历史记录,对开关柜“状态维修”提供科学数据依据。
对开关柜等电器设备的安全运行具有重要的意义。
二、高压开关柜无线测温系统设计原理2.1系统的主要组成无线测温系统主要由无线温度传感器、无线测温装置、监控中心上位机、通信链路构成,其中无线测温装置主要安装在开关柜面板上,用来收集各子无线温度传感器的数据,并进行处理和储存,所有的无线测温装置都利用RS485总线和监控中心上位机进行通信,从而组成分布式监测系统。
2.2无线温度传感器无线温度传感器主要用来测量带电物体表面温度,如对高压开关柜中的母排接头和裸露触点的运行温度进行监测。
无线温度传感器主要包括测量电路、温度传感器、无线调制接口、逻辑控制电路、供电电路。
通过无线网络将温度信号传送到无线温度监测仪。
无线温度传感器由于体积比较小,适合用来测量开关柜中的温度热接点,可以对开关柜中引出电缆接头,触头、母线连接点的运行温度进行测量。
