Proven heavy-duty tacho generator TDP

TDP Tacho generators are analog transducers for instrumentation and control technology. The permanently excited tacho generators form the speed with which they are driven to a voltage proportional to that speed. Thanks to their robust design and construction TDP tacho generators are suitable for larger industrial drives. Depending on the requirements the tachogenerators are produced in customized sizes and connections as well as in a variety of voltage versions. TDP tacho generators are available with IP rating IP55 to IP67.
