IS230SNRTH2A GE 温度变送器

品牌: GE

型号: IS230SNRTH2A

产品描述

温度变送器一般由基准源、冷端补偿、放大单元、线性化处理、V/转换、断偶处理、反接保护、限流保护等电路单元组成。它是将热电阳产生的电阳经冷端补偿放大后，再帽由线性电路消除电阳与温度的非线性误差，后放大转换为420mA电流输出信号、为防止热电阳测量中由于断丝而使按温失效造成事故，变送器中还设有断电保护电路。当热电阳断丝或接解不良时，变送器会输出大值(28mA) 以使仪表切断电源、温度变送器模块为24V供电、二线制或三线制的一体化热电阻。产品采用进口集成电路，将热电阳的信号放大，并转换成4-20mA的输出电流 05V的输出电压，其中铠装变送器可以直接测量气体或液体的温度特别适用于低温范围测量，克服了冷凝水对测温所带来的影响.

又如，用软件实现信号滤波，如快速傅立叶变换、短时傅立叶变换、小波变换等技术，是简化硬件，提高信噪比，改善传感器动态特性的有效途径。

还如，充分利用人工神经网络技术强有力的自学习、自适应、自组织能力，联想、记忆功能以及对非线性复杂关系的输入、输出间的黑箱映射特性等。

当前，我国智能化领域最薄弱、最需要发展的是仪器、仪表、传感器等基础产业。随着科学技术的飞速发展和自动化程度的不断提高，我国仪器仪表行业也将发生新的变化并获得新的发展。仪器仪表产品的高科技化，特别是智能化，将成为日后仪器仪表科技与产业的发展主流。

IS230SNRTH2A GE temperature transmitter

Brand: GE

Model: IS230SNRTH2A

Product description

Temperature transmitter is generally composed of reference source, cold end compensation, amplification unit, linearization processing, V/ conversion, break pair processing, reverse protection, current limiting protection and other circuit units. It is the thermoelectric positive generated by the cold end compensation amplification, and then the cap by the linear circuit to eliminate the positive and temperature nonlinear error, after amplification into 420mA current output signal, in order to prevent the thermoelectric positive measurement due to broken wire and temperature failure caused by the accident, the transmitter is also equipped with a power off protection circuit. When the thermoelectric positive is broken or poorly connected, the transmitter outputs a maximum value (28mA) to enable the meter to disconnect, the temperature transmitter module to supply 24V, and the integrated thermal resistance of two or three wire systems. The product adopts imported integrated circuit to amplify the signal of the thermoelectric positive and convert it into 4-20mA output current 05V output voltage, in which the armoury transmitter can directly measure the temperature of gas or liquid, especially suitable for low temperature range measurement, overcoming the influence of condensate water on temperature measurement.

For another example, using software to realize signal filtering, such as fast Fourier transform, short-time Fourier transform, wavelet transform and other technologies, is an effective way to simplify hardware, improve signal-to-noise ratio, and improve the dynamic characteristics of sensors.

For example, make full use of artificial neural network technology powerful self-learning, self-adaptation, self-organization ability, association, memory function and black-box mapping characteristics between input and output of non-linear complex relations.

At present, China's intelligent field is the weakest, the most need to develop instruments, meters, sensors and other basic industries. With the rapid development of science and technology and the continuous improvement of the degree of automation, China's instrument industry will also undergo new changes and obtain new development. The high-tech and especially intelligent instrumentation products will become the mainstream of the development of instrumentation technology and industry in the future.
