在合信的方案中，热辊的温度测量采用无线输电载波通讯（CTS5 TIT测温系统）方式，即热辊上的传感器信号是通过无线传输的方式传送到上位控制系统，完全省却通过滑环传递温度信号的环节，避免了集电环和电刷接触造成的温度测量不准，也节省了定期更换集电环和电刷的维护成本。同时在测温环节采用16Bit精度的模拟量模块EM231-7HC32,温度测量精度为0.1度。EM231-7HC测量模块采用先进的硬件滤波，稳定性高于标准PLC温度测量模块。
CTS5 TIT无线测温系统使用热电阻温度传感器，测量的真实温度。而传统热辊采用热电偶的温度检测方式，其测量的温度是相对于冷端（一般是温控器内部）的温度，即测量的是相对温度，这个值相对于真实温度会有一定偏差

In the Hexin scheme, wireless transmission carrier communication (cts5 tit temperature measurement system) is adopted for the temperature measurement of the hot roll, that is, the sensor signal on the hot roll is transmitted to the upper control system through wireless transmission, completely eliminating the link of transmitting temperature signal through the slip ring, avoiding the inaccurate temperature measurement caused by the contact between the collector ring and the brush, and saving the maintenance cost of regularly replacing the collector ring and the brush. At the same time, the analog quantity module em231-7hc32 with 16bit accuracy is used in the temperature measurement link, and the temperature measurement accuracy is 0.1 degree. Em231-7hc measurement module adopts advanced hardware filtering, and its stability is higher than that of standard PLC temperature measurement module.
Cts5 tit wireless temperature measurement system uses thermal resistance temperature sensor to measure the absolute real temperature. The traditional hot roller adopts the temperature detection method of thermocouple, and the measured temperature is relative to the temperature of the cold end (usually inside the thermostat), that is, the measured temperature is the relative temperature, which will have a certain deviation from the real temperature
