Technical specification:

Transmitter 6746 is exceptionally versatile accepting almost all the most common temperature sensor inputs and process inputs as well. The transmitter has frequency output 02.5 kHz. The use of counters provides an economical means of transmitting measuring data to instruments where an analog input is not possible or when a more cost-effective solution is sought after. The programming of the transmitter is simple by the MekuWin configuration software or with the hand held programmer 6790, which is especially practical in field conditions. Emissivity can be set according to the measuring target. A high measuring accuracy is reached by a 16-bit analog converter, the linearity of which is < 0,005%. Conversion accuracy of the output is 0,05% wihout linearization error of the sensor. Inputs and outputs are galvanically isolated from each other and the power supply. The transmitter is an excellent choice when one wants to reduce the number of instruments in storage by replacing several models with one transmitter.		Thermocouples: Sensor Range	Linearity
