Nokeval 6841 Transmitter for Strain Gauge Sensors
6841 is a DIN rail mounted strain gauge / weighing transmitter. It is equipped with a small display and push buttons to allow configuration without a separate programming device. There is also two alarm relays, analog output, and RS-485 serial output with Nokeval SCL and Modbus protocols. The sensor can be connected using 6-wire measurement to eliminate wire resistance effect. Sensor excitation is about 10 V DC.
The device can be calibrated / teached in up to six points.
