Turbine Flowmeters
-
Titan’s small turbine flowmeter range use a radial flow principle based on the Pelton wheel technique. This well proven method is the ideal way of measuring low rates of flow of low viscosity liquids. For these mini flowmeters, a jet of fluid is directed at a turbine that is mounted on robust low friction sapphire bearings. The geometry of the turbine and the fluid chamber ensures that the rotational speed of the rotor is proportional to the flow rate through the device. The use of this radial arrangement allows more energy to be imparted into the turbine, so the bearing drag is far less important. Furthermore, because more energy is available the bearings themselves can be a lot stronger so increasing the life of the flowmeter. For larger flows, some of the liquid can bypass the turbine chamber, which then behaves as a “shunt” to the metered fluid. Accuracy is still maintained and the output remains linear.

Linear Slide
M-011
-
Physik Instrumente GmbH & Co. KG
M-011 ultra-high-precision magnetically-coupled stages use the force of integrated magnets to preload the bearing. This magnetic preload results in extremely uniform and smooth motion with minimum friction. Unlike conventional stages, where two bearings with limited parallelism guide the carriage (inducing runout and rotational errors) in M-011 stages, only one of the two linear bearings has a guiding function (V-groove) while the second bearing is for support only (U-groove).

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.

Hydrogeology
SID
-
SID calculates hydraulic sections of any form and of any geometrical and hydraulic characteristics. The program determines, for a given section, the height and speed values reached by the water, assuming that the channel has a prismatic form of infinite length. The formula used by the program utilises the average velocity as a function of the mean radius of the section, that is equal to the ratio between the area of the hydraulic section and the wet boundary, of the loss of load and of the friction coefficient.

Powder Brake Dynamometers
PB Series
-
The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of 0.3% to 0.5% full scale ( 2% for PB 2.7), depending on size and system configuration. Additional mounting possibilities include speed pickup and OEM version IS.
