, Summary
XTWKseries of digital electronic temperature switch using PT100 sensor. Reliable quality, advanced technology, small volume, light weight, directinstallation, output, lower two relay switch signal and 4-20mA for subsequentinterlocking control or alarm. Can be used in industrial process control and scientific research and other key places, and may provide for the followingplaces:
* require current telemetering and alarm, place.
* can be used for a long time in the open air.
* the intrinsically safe type can be used in hazardous locations.
* can be directly installed in the pipeline, equipment, without mounting bracket.
* can not open the lid of the case, the external key continuous adjustment, alarmand alarm hysteresis value.
