Introduce: In a lot of equipment need undertakes temperature measure, when using thermocouple to undertake metrical, those who reduce interference to assure to collect temperature is accurate be with stability in majority application is indispensible. Grind China ADAM-4118 is solid model the automatic filter function that thermocouple collects module (Auto-detecting Noise Frequency Function) can the frequency according to noise is wide come frequency of self-correcting filter wave, can filter effectively thereby interference. It is ADAM-4118 below the application of function of automatic when the temperature in extruder detects interference rejection. Systematic configuration: In extruder, each temperature test point receives ADAM-4118 to undertake metrical through thermocouple, in PLC conveying temperature data in the meantime, undertake the system is monitored with control. In the meantime, PLC sends HMI to feel the real time in screen to show temperature temperature data again. Extruder: Problem description: The client has used ADAM-4018+ to have period of time, when the electric machinery on the extruder that start, the temperature value that through HMI feeling screen sees always is in happen jump change, and actual temperature did not produce rapid change; Analysing a reason is the electromagnetism that electric machinery starts interference brings about ADAM-4018+ temperature to collect insufficient stability. Means of settlement: Solid model ADAM-4118 increased " automatic filter wave " new function, this function can monitor the highest frequency that disturbs signal automatically to filter its effectively. Accordingly, the temperature value that gets is more exact with stability. Grind China the engineer changes ADAM-4018+ to spot hind for ADAM-4118, after the simple configuration that undertakes as follows, the temperature when solving electric machinery to start is collected jump the problem that change. The hardware interface means because of ADAM-4118 and ADAM-4018+ and software communication agreement are completely compatible, so the installation means of user hardware system, program need not make any changes etc, solve this problem easily already. Install measure: Measure 1: ADAM-4118 lateral setting switch is put in " Init " the position, new electrify, ADAM-4118 enters initialization mode. Nextpage measure 2: Open Adam. NET Utility searchs ADAM-4118. In " Integration Time " change in the project for " User Defined " .
Mode. Click " Apply Change " in order to decide a setting. Measure 3: In ADAM.
The choice in Net Utility " Advanced Setup " click " Scan " the highest frequency that violates a source in order to scan, should start interference source continuously in scanning process (wait like electric machinery or transducer) measure 4: After the setting is finished, put switch of ADAM-4118 lateral setting in again " Normal " the position, new electrify, examine result, temperature value did not happen jump changed. Summary: In industrial spot or equipment, voltage / electric current / of temperature signal all round often accompanying interference source to wait like power source of high-power electric machinery, starter, transducer, high-power, these interference sources can affect the performance that collects to signal. Grind the function of automatic filter wave that Hua Jiang solid imitate measures data to collect module ADAM-4117 and temperature to collect module ADAM-4118 needs to be installed simply only, can avoid effectively to disturb a source to collect brought worry to signal, enhanced the interference rejection ability that data collects greatly, those who made sure data is collected is accurate with stability.
