Preventing Breakdowns on Mixer Production Lines

stork preventing breakdowns with a highly accurate torque measurement solution 1

clientsThe Client

 Datum Electronics was approached by a gypsum manufacturer, who was looking for options, which would allow them to monitor the viscosity of gypsum fluid in their mixing tanks, during the production process. The company had been experiencing significant damage to their motors, due to the high pressure applied to the rotors, by the thickening gypsum fluid, a process which happens extremely quickly. These breakdowns were proving to be extremely costly, not only to fix the motors, but also in the downtime of the mixers.

eyeThe Challenge

  With an addition of a torque sensor, the company was hoping to observe the torque being applied to the motors, allowing them to extrapolate the viscosity of gypsum fluid. However, it would need to be a very special torque sensor to do this job. Apart from the high speed and torque to be measured, the mixing shaft was situated in an extremely harsh environment, being subjected to large amounts of fine dust and liquid splashes. Hence, the customer wanted a transducer, which would be able to withstand the harsh environment and become an extension of their current motor/mixer shaft.

puzzleThe Solution

Datum’s solution to this challenge, was to design a bespoke RS425 torque sensor, with a TDX shaft matching the customer’s own driveline. This torque measurement solution enabled the customer to connect directly into their existing drive line, without the need for additional couplings, saving both time and money from an unnecessary production stoppage.

bullseyeThe Impact

Although being custom built, the RS425 torque sensor used the same strain gauge technology as Datum’s standard torque sensing products, providing a high accuracy of 0.1%, ability to withstand high speeds and operate in the harshest of conditions.

Having the Datum torque sensor installed not only helped protect the mixers’ motors, but also enabled the customer to improve batch consistency by matching the same viscosity with every consignment.

Contactless Torque Transducer

RS425 250Nm

These contactless Torque Transducers are not limited by operational speeds, can fit any shaft and capable of measuring torque from 1nm and up to 500knm, providing highly accurate and reliable torque measurement in many applications.

The Datum Electronics Series RS425 contactless torque transducer has been designed to fit easily in line with any drive-train or test rig, using either a spline or key-way shaft. This type of torque sensor has many advantages over other torque measurement systems, including zero bearing friction, high speed and high torque applications.
