What is the advantage of temperature transmitter?

In the product of temperature instrument most would use the temperature transmitter. In the industrial field, the temperature transducer is applied to the most simple measurement of costs is not higher than wiring cost directly, and the use of such a transmitter can save time, avoid a series of maintenance headaches. Especially when the measurement point is quite a long way from the control room, this kind of connection with transmitter has more features and advantages. Here is to introduce the advantages of measuring temperature transmitter: one, reduce the cost of wiring using direct wiring to need remote control system of the sensor wiring, wiring over a long distance, not only wire itself is very easy to damage, cost and the cost is quite high. Second, protect the signal from the interference at present in many industrial environments, wireless radio frequency interference and electromagnetic interference will seriously affect the process of measuring signals, and the temperature transmitter first converting sensor signals into analog signals ( For 4 - commonly Ma, or 0 to 20 10 v) , and then transfer, which can effectively improve the influence. Three, to reduce hardware and storage costs when using direct wiring, sensor types and DCS/PLC and controller input interface card matching is very necessary. Than 4 - sensor input interface card 20 ma every electrical input interface card you lot, when a factory in a large number of using different types of sensors, you need to buy a lot of different types of kanban CARDS do backup, it isn't just a matter of cost consumption, and artificial. Fourth, to strengthen the accuracy and stability using temperature transmitter can strengthen the accuracy of measurement. The reading of DCS and PLC system in a wider range of sensors. As is known to all, small measuring range can obtain higher measurement precision, so the temperature transmitter can be calibrated in all sensors measuring ability of any interval, the measuring accuracy is higher than the precision of the measurement strategy layout should be directly. Five, the simplified engineering to prevent false wiring use temperature transmitter can replace various sensor wire connection channel and DCS/PLC controller, can greatly simplify the engineering design drawings, simply indicate the type (when the design Twisted-pair 4 - 20mA） Can, such as a conductor and a tablet system means that the future maintenance operations have become simple and easy, and those four wire resistance three wire resistance, high - — Low end from now on is not considered, and also reduces the possibility of eliminating circuit wiring error. 温度计温度发射机主要用于产品。 在工业领域,将温度传感器应用于最简单的测量的成本不高于直接连接,并使用这样的发射机可以节省时间和避免一系列头疼引起的维护。 特别是当测点远离控制室,连接发射机有更多的特色和优势。 下面是介绍温度传感器测量的优点:我。 减少布线costsSensors使用直接连接控制系统需要长期 布线的距离。 当线路长, 距离,不仅线本身很容易断,而且成本很高。 2. ——保护信号 网站interferenceAt存在,在许多工业环境中,射频干扰和电磁干扰将严重影响测量信号,首先和温度传感器将传感器信号转换成模拟信号( 通常4 - 20 mA或0 - 10 v) ,然后传输,可有效改善的影响。 减少硬件和存储costsWhen使用直接连接,需要匹配的传感器类型与DCS和控制器的输入卡/ PLC。 传感器输入比4 -董事会更贵 20 ma输入董事会。 当不同类型的传感器广泛应用于工厂,大量的不同类型的董事会需要购买备份。 这不仅是一个成本的问题,但也是一个手册的问题。 4 加强准确性和stabilityThe测量精度可以提高使用温度传感器。 DCS和PLC系统的测量读数范围广泛的传感器。 我们都知道,一个较小的测量范围可以达到更高的测量精度,因此,温度传感器可以在任何范围的传感器的校准测量能力,测量精度远高于直接连接的测量策略。 V。 简化的项目,以防止MisconnectionThe使用温度传感器可以取代许多传感器电线的连接通道和DCS /控制器。 它可以极大地简化工程设计图纸。 它只需要注明类型( 双绞线4 - 20mA) 在设计。 这样一个导体和一个输入系统意味着维护操作在未来将变得简单和容易的。 这四个, 线电阻、3 - 线电阻,高- 结束- - - 低收入 电阻是永远也不可能从现在开始结束。 还在考虑,减少的可能性,消除电路误接
