Agilent HP 5517B Thermostatic Control

HP 5517B control system adopts fx2n-64mr plc, with programmable controller as the core, to form a closed-loop control system integrating acquisition, processing, display and automatic control of temperature. The level value in the tank, its analog converted to switching for control, temperature control through the RTD and RTD module and then pid adjustment, get the deviation to control the efficacy of the heating device. When a heating device is used for heating, the RTD is selected as the temperature sensor.

HP 5517B through the plc analog expansion module RTD on the collected temperature data, the module itself will linearize the processing, cold end compensation, without any external transmitter or external circuit, you can complete all the data acquisition and data processing functions. After the operation by pid, a difference value is obtained to regulate the power of the thyristor. Using led display tube to show the collected temperature value, in order to facilitate the control of water temperature in various tanks, can be put through a dial dial input data to plc, the given temperature value for modification.
