DALLAS®-sensors of the DS1820 type are used as temperature probes and which can be connected up to 60 m. Between PC and sensors a microcontroller module for the RS232 interface is plugged in. The sensors are identificated by their serial number. The "in the adapter" integrated microcontroller drives the RS232 bus, manages the serial numbers and captures the temperatures of the connected sensors cyclically. The current measuring values are displayed as ASCII string via the RS232 interface to the connected PC. The recording of the measured values happens online with the PC. With the software extensive monitoring and controlling functions are possible.
The temperature sensor is not included in the package.
