The digitized temperature data is then formatted into ASCII characters and transmitted via the RS232 interface to a host system. The galvanic isolation between the thermocouple input and the communication/power circuits ensures that electrical noise, ground potential differences, or transient voltages do not affect the measurement accuracy or damage connected devices.
