SEW-EURODRIVE: Introduction of a New PK Temperature Sensor (PT1000) to Replace the KTY Temperature Sensors

DCS SEW EURODRIVE New PK Temperature Sensor 1 400

February 15, 2022

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.

 

Advantages of a PT1000 Temperature Sensor

  • Component with standardized characteristic curve in accordance with IEC 60751 
  • Characteristic curve is comparable to that of the KTY temperature sensors
  • Available worldwide from different manufacturers
  • The function that allows signals to be evaluated in the inverter is integrated+++

 

Your Benefits:

  • •Easy integration of the temperature sensor into the system concept 
  • using the standardized characteristic curve in accordance with IEC 60751.
  • A smooth switch from KTY to PK (PT1000) is possible

    since the integration takes place simply by modifying the inverter firmware.

  • Worldwide availability of component parts and guaranteed serviceability

    since the sensor can be ordered from multiple manufacturers.

  • The function that allows signals to be evaluated in the inverter

    is integrated by modifying the firmware, thus making hardware changes unnecessary.

Conserving Power and CO2 Emissions with Premium Efficiency Motors

The process of converting electrical energy to mechanical energy is never perfect. As much as we would like to have a 100% efficient motor, it is impossible to build a machine that will take 746 watts of electricity (the equivalent of 1 Hp) and convert it to 1 Hp of mechanical output. It always takes somewhat more than 746 watts to yield 1 Hp’s worth of output.

Motors are continuously being pushed to be more efficient and reduce these losses. Over the years the guiding regulations of motor manufacturing have pushed us to improve efficiencies to new levels to reduce the considerable global power consumption of motors, as they are everywhere. From our factories, utilities and homes and most anywhere you can think of.

How much power consumption aka money are you spending that you do not have to? Take a minute while having your coffee to see if you can save money.
