DIN Rail Mountable Strain Gauge Sensor Transmitter
Novekal 6841 is a DIN rail mounted strain gauge sensor / weighing transmitter. It is equipped with a small display and push buttons to allow configuration without a separate programming device. The transmitter has two alarm relays, analogue output, and RS-485 serial output with Nokeval SCL and Modbus protocols.
The strain indicator can be linked using either a 4-wire or 6-wire connection, providing high-precision measurements. The transmitter provides a 10 V bridge voltage and directly measures it at the sensor pins with the 6-wire connection. This approach eradicates voltage drop caused by sensor wire resistance, enabling the use of slender sensor cables without sacrificing accuracy.
The device can be calibrated/taught in up to six points.

What is a DIN Rail Mountable Transmitter?
A DIN rail mountable transmitter is an electronic device designed to be conveniently mounted on a standard DIN rail in industrial environments. It receives input signals from sensors and converts them into suitable output signals for control and monitoring purposes.What is a Strain Gauge Sensor?
A strain gauge sensor, is a device used to measure mechanical strain or deformation in objects. It consists of a thin wire or foil that changes resistance when subjected to strain.What is a Strain Gauge Transmitter?
A strain gauge transmitter is an electronic device that receives signals from strain gauge sensors, amplifies and converts them into standard output signals like 4-20mA, facilitating remote monitoring and control.What is a Strain Gauge Used For?
Strain gauges, sometimes referred to as a gage sensor, are utilised for measuring mechanical strain or deformation in objects. They find applications in stress analysis, load measurement in bridges and buildings, structural health monitoring, and various engineering and industrial fields requiring accurate strain measurements.How Do Strain Gauges Work?
Strain gauges work by converting applied force, pressure, tension, or weight into a change in electrical resistance. As the material being measured changes shape under force, the strain gauge also changes shape, allowing the measurement of the strain or force experienced by the object.Related products
