- The TWS™ -200 is an individually sold temperature sensor that is field-assembled in a series to create a measuring chain designed for monitoring and mapping the temperature of a stator core and/or windings on large machines. Once assembled, a typical measuring chain is composed of a maximum of 100 sensors and one HAVSM™-100 communication interface. The chain is then connected to a ZPU™-5000 acquisition unit or a server through an RS-485 network.
