June 23, 2011, Newell, West Virginia, USA – Servo-Tek Products, Inc. (Servo-Tek), today announced the global market introduction of its D-Series, a highly rugged industrial tachometer generator family, designed to offer high-reliability support for a variety of instrument-grade velocity sensing applications where high-output voltages (45 VDC / 1000 RPM) are required, such as precision integrators and velocity servo systems.
Combining high-accuracy with low driving torque, Servo-Tek tachometers provide a convenient and economical means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and feedback control. The distinguishing feature of the D-series is its low-rippled output, for which the ripple RMS value will not exceed less than 3% of the DC value at any speeds in excess of 40 RPM on standard units. Linearity at any speed is better than 0.1% of the total output at that RPM. In addition, the rugged design and construction of the D-series features commutators manufactured from an alloy containing at least 90% silver; armature laminations, which are wound with ISOMID insulated wire over Teflon® slot insulation; and a fully baked armature, resulting in a NEMA Class H insulation system rating, for reliable performance to an internal operating temperature of +180°C (+356°F). In addition, the units feature Mil-C-5541and Mil-A-8625 chemical film coatings for maximum corrosion protection, facilitating their use within harsh industrial environments.

About Servo-Tek Products Inc.
Servo-Tek Products, Inc., is a world renowned manufacturer of instrument-grade tachometers and low-cost encoders. Servo-Tek tachometers provide a convenient and economical means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and feedback control. Combining high-accuracy with low driving torque, Servo-Tek tachometers are ideal for use in servo systems. They are particularly well-suited to precision integrator and velocity servo applications, both of which require a high linear speed and voltage relationship with minimum ripple of <3% of the DC value at any speed in excess of 40 RPM. Servo-Tek encoders are designed to adapt to DC motors and meet typical industry requirements for a low-cost, easy mount digital feedback device. Their simplistic design incorporates both housing and hub into a single assembly, alleviating the need for tedious coupling or alignment procedures. The company’s recent acquisition by the Bellofram Group of Companies has moved its headquarters to Newell, West Virginia, USA, where customers can benefit from increased technical sales and customer service support.
