Industry standard torque transducer with rotary shaft and static body.
The latest technology Datum Electronics Series M420 non-contact rotary torque transducers have been designed to fit with most applications and solutions requiring rotary torque measurement. The torque transducer fits inline with the drive train or test bed, using standard keyway shafts. A non-contact transmission system provides a digital USB output directly proportional to torque, in this variant it is supplied as a complete transducer with bearings to support the stator unit on the rotating shaft. It is suitable for most general test rig applications.
The M420 torque transducer utilises a strain gauged shaft for accurate and reliable torque measurement and a set of rotating on shaft conditioning electronics, the digital signals are transmitted to the non-rotating part of the system or stator providing a reliable and highly accurate torque measurement solution.

The Competitive Edge
The Series FF420 transmits calibrated digital data as this is a cleaner and more defined method of transmitting data. The on-shaft signal from the strain gauge is converted to a digital signal and amplified on shaft. It is this signal that is taken off the shaft and processed by either an indicator or by TorqueView, providing the end user with clean and definitive data transmission.
Instrumentation
The Series M420 transducer is compatible with Datum’s full range of torque indicators (Type 300 torque indicator, Type 310TSP portable torque, speed & power indicator, Type 370 (torque, speed and power indicator) via a serial port connection between the transducer and indicator.

A popular option is to view data from the transducer on a PC or laptop for torque data analysis. Our TorqueLog software has been developed to allow the user to view the torque data in real time with optional data analysis for performance monitoring and control. Using a simple USB interface, the transducer data can be displayed and logged at the touch of a button with TorqueLog.
Analogue Options
If an analogue signal is required, our Series 420 torque transducers are able to provide either 4-20mA or 0-10VDC output by converting the digital data signal from the torque transducer to an analogue signal. However, the effect of external or electrical noise can impact upon signal strength and definition in this instance. Other commercial applications may use slip rings or analogue signals to transmit data, but the Datum Electronics series 420 outputs digital as standard.
If your requirements dictate anything above our standard torque transducer range of 10,000Nm we can and have engineered torque transducers up to 500,000Nm.
