Slip-Ring Motor Starting Panels
Rotor Starter
The Slip-Ring Motor Starters are based on the series of resistors that are applied to the rotor circuit to control the speed/torque characteristics of the motor. Rotor starters are mainly used for the motor starting applications requiring high-starting torque like loaded belt conveyors in mining industry. By external resistors, it is possible to shift the motor maximum (break-down) torque up to starting torque point for motors under heavy loads during start-up. The resistors are splitted into some steps and controlled via contactors by motor starting control system. As the motor speed increases, the external rotor resistors are eliminated by shorting contactors until all external resistors are shorted out.

Slip Rings Separates
Separates are typically rings and insulation material assembled on an axis along with separate contact brushes. They are usually designed with flying leads. Once integrated, they provide electrical contact between stationary and rotating parts of a slip ring assembly. They use bearings from the host system and provide a more compact and economical solution than self-contained Slip Rings. The coupling of these items requires technical skills from the OEM and is suitable for applications that have tight mechanical requirements.

Displacement Transducers
Procter & Chester Measurements Ltd
Pressure: Measures gas or liquid pressure. Pressure is an expression of the force required to stop a fluid from expanding. The transducer generates a signal from the pressure imposed upon it. Torque: Measures the torque (or twisting motion) on a static or rotating system. The static torque element has little movement and therefore more economic to manufacture and purchase. Rotary or dynamic torque is more complicated as the signal needs to be transferred using slip rings, wireless telemetry or rotary transformers/inductance technology so that the strain gauged shaft can continuously rotate. Displacement: Measures distance. The displacement transducers that PCM offer are slightly different to standard units. They have a strain gauge/wheatstone bridge. The benefit here is that if the customer has existing electronics that uses strain gauge/load cell technology, they can use them with these sensors.

Slip Table Assembly
CSTA Series
Unholtz-Dickie introduced the Combined Slip Table Assembly (CSTA) in the late 1960''s to meet the demand for positive mechanical alignment between the shaker and its companion horizontal slip table. The challenge was to achieve this positive, permanent alignment feature without requiring an expensive seismic mass in the vibration lab floor. The original CSTA design has been continuously improved over the years and has now become the industry standard for permanently aligned, integral reaction mass slip tables.

3-Component Quartz Force Rings
260 Series
Three-component quartz force ring sensors are capable of simultaneously measuring dynamic force in three orthogonal directions (X, Y, and Z). They contain three sets of quartz plates that are stacked in a preloaded arrangement. Each set responds to the vector component of an applied force acting along its sensitive axis. 3-component ring force sensors must be statically preloaded for optimum performance. Preloading provides the sensing elements with the compressive loading required to allow the proper transmission of shear forces. Versions are available with ranges up to 10k lb (45k N) in the z-axis (perpendicular to the top surface), and up to 4000 lb (18k N) in the x-and y (shear) axes. Both ICP® and charge output styles are available.
