Transcription

1 SINEAX VK 66 for RTD and TC inputs, with HART procol for installation in the terminal head of a temperature sensor DIN 79, shape B Application II () G SINEAX VK 66 is a two-wire head-mounted transmitter. It is designed for measuring temperature in combination with thermocouples or resistance thermometers. Thermocouple non-linearities are aumatically compensated. The output signal is a current in the range ma. Measured variable and measuring range are programmed using a PC with a suitable interface and running the programming software. The sensor circuit is monired for open and short-circuits and the output responds in a defined manner if one is detected. The power supply of ( V DC) is connected gether with the signal by the two leads connected the measurement output (loop powered).
