SEW‑EURODRIVE will soon offer its customers the opportunity to use modern PT1000 temperature sensors for winding temperature analysis. The PT1000 temperature sensors serve as a replacement for the KTY sensors, which were discontinued by the manufacturer, and will be available for selection in numerous SEW‑EURODRIVE products under the option designation "PK."

The KTY84 – 130 temperature sensors have been used since 2004 in numerous motors from SEW‑EURODRIVE to ensure thermal protection of the motor winding. The temperature sensor's measurement values are processed in a frequency inverter or in a separate evaluation unit. In February 2015, NXP officially announced that the KTY temperature sensors would be discontinued. As a replacement, the PK temperature sensor (PT1000) for thermal monitoring of the motor is available immediately from SEW‑EURODRIVE for multiple motor series. Many inverters from SEW‑EURODRIVE are already able to interpret the new temperature sensor's measurement signals.

Information

Drives with the PK (PT1000) temperature sensor can only be operated on inverters that have appropriate evaluation electronics. SEW-EURODRIVE guarantees the supply availability and serviceability of the discontinued KTY temperature sensors for the next several years; if service is needed, we can offer you a solution.
