CVT/APS transmission

CVT/APS transmission in agriculture hydraulic applications - Danfoss

Control transmission to improve performance

In the transmission system temperature control of the oil is vital to maximize efficiency and prevent down time. MBT 3270 temperature sensor controls the temperature to avoid damages to the transmission.

Pressure control in transmission systems improves performance, MBS 1250 pressure transmitter ensures clutch engagement and that the line pressure is controlled to balance the torque in the transmission and avoid power loss. Exact pressure and temperature control ensures maximum performance and reduces down-time.

CVT - Continuously Variable Transmission, is an automatic transmission commonly used in agricultural applications. APS - Automatic Power Shift, is typically used in construction and material handling applications.
