New torque sensor harvests data in agriculture
PTO Sensor 7300 is more compact and easier to install
Munich/Oberhaching, March 16, 2023: NCTE is launching a new non-contact torque sensor for tractor power take-off (PTO) drives, completing its portfolio in the agricultural sector. The compact sensor is equipped with the 1 3/8″ 6-piece spline standard for immediate use and can be mounted between the tractor and attached agricultural machine without tools.
The PTO Sensor 7300 features high accuracy up to ± 0.5% and a torque range up to 3000 Nm. In addition, the new sensor has integrated speed detection and IP65 protection for the robust environmental conditions in agriculture.
Using magnetostriction, the sensor measures loads and load changes on the drive shaft of water pumps, mowers, loader wagons and many other agricultural attachments without contact. With a laptop via plug & play (only one USB cable) or via analog output signals, users set up a control loop and adjust their cultivation machines in a demand-optimized and efficient way.

Digitalization in agriculture
For the ecological use of an agricultural machine, operation at the optimum load point is essential. The torque signal is used as a control variable, for example, to optimize the discharge rate of a fertilizer spreader or to adjust the baler for a maximum throughput of the material to be baled (hay or straw). The sensor technology also monitors the operating status or wear in real-time for predictive maintenance. For agricultural machinery manufacturers, the sensor technology provides important data for development work in field tests.
“Data is the crop of the future in digital agriculture. With our sensor technology, agricultural companies reduce raw material costs and meet the needs of an increasingly green industry,” says Jürgen Uebbing, CEO of NCTE AG.
Torque measurement defies harvest juices and stone chips
The greatest challenge for sensor technology in agriculture is the working environment: The non-contact measurement based on elastic magnetostriction with protection class IP65 makes the PTO Sensor 7300 extremely robust against external influences. Even vibrations, dirt, oil, aggressive crop juices or falling rocks do not affect the magnetic field measurement.
The new agricultural sensor achieves all this in a very compact form, 12 cm smaller and 9 kg lighter than the predecessor model PTO 7000 with the same couplings.
The data of the PTO 7300 agricultural sensor at a glance:
- Torque: 0-3,000 Nm
- Speed measurement: up to 1,100 rpm
- Direction of rotation: CW and CCW
- Accuracy: ± 0.5%
- Temperature range: -40°C to + 85°C
- Protection class: IP 65
- Output signals: 0-10 V, 4-20 mA, CAN bus or USB
