Viscosity & Flow Measurement
Viscosity is perceived as ‘thickness’ or resistance to pouring, but there is more to viscosity than this. All fluids have an internal friction between molecules, which determines how well fluid flows. Due to this internal friction, energy is required to move the liquid and viscosity is the measure of the resistance to flow. Elcometer manufactures and supplies a wide range of viscosity gauges from flow cups to dip cups to rotational viscometers.

Production Test Stands for Electric Motors
Electric drives such as DC and EC motors are more and more extensively deployed in the automotive industry. At the same time there is an increasing requirement for a 100% analysis of motors for fault detection and error analysis as well as statistics on quality, without increasing production cycles times. The model-based Parameter Identification method (PI method) from imc allows testing to be performed under load, yet without an “explicit” separate load machine. Instead, the motor is loaded dynamically by exploiting its own inherent inertia. This allows motor parameters such as resistance, inductivity and friction to be determined within a few seconds. A mathematical model and its parameters reflect motor behaviour in its completeness and make it possible to monitor motor production based on limit values and trend statistics. The identified parameters of the model equation can then be used to calculate derived key performance indicators of the motor characteristic curve.

Washability & Abrasion
Improved mechanical resistance to wear is a key requirement of a wide range of products. From coatings to clothing, leather to upholstery, keypads to plastic toys, a product’s ability to resist wear is an important characteristic.
