ABB STX Serial Wireless Temperature Sensor User Manual

ABB STX Serial Wireless Temperature Sensor

Product Overview

The ABB STX serial wireless temperature sensor is a self-powered smart sensor designed to continuously monitor the temperature of critical connections by harvesting electromagnetic energy around power transmission conductors. The sensor wirelessly transmits data to the concentrator, which is then stored in ABB Ability local or cloud-based solutions to enable different digital services. This product is a key data source in ABB’s monitoring and diagnostic solutions.

Product Features

• Self-powered wireless smart sensor
• Harvests electromagnetic energy to power itself
• Continuously monitors temperature of critical connections
• Wirelessly transmits data to the concentrator
• Stored data in ABB Ability local or cloud-based solutions
• Wide measurable range: -40°C to 130°C
• Excellent accuracy

Product Usage Instructions

1. Install the ABB STX serial wireless temperature sensor around the power transmission conductor.
2. The sensor will continuously monitor the temperature of critical connections and wirelessly transmit data to the concentrator.
3. The concentrator will store the data in ABB Ability local or cloud-based solutions.
4. To access the data, log in to ABB Ability and navigate to the appropriate section.
5. The measurable range of the sensor is -40°C to 130°C. If the temperature goes outside of this range, the sensor may not function properly.
6. If you have any questions or concerns about product usage, please refer to the user manual or contact ABB customer support for assistance.

Overview

ABB STX serial products are the key data source in ABB’s monitoring and diagnostic solutions. This self-powered wireless smart sensor harvests the electromagnetic energy around power transmission conductor, continuously monitors the temperature of critical connections and wirelessly transmits to the concentrator. Eventually, the data will be stored in ABB Ability local or cloud-base solutions to enable a variety of different digital services.

Start installation

Sensor boy

1. Use the scissor to cut off the ferromagnetic ribbon, the length should be 100-150mm longer than the surface perimeter of the measured conductor or cable.
2. Cut two edges of ferromagnetic ribbon to an arc, to make it safer.
3. Put the ribbon through the metal buckle from one end, then bend it’s extremity with an angle at 90° longer than 10mm.
4. The ribbon goes through the sensor, ties it to the measured conductor or cable.
   • The position of sensor shall be in the middle of conductor, meanwhile the thermistor shall be at the closest position of the connection.
   • To improve insulation level, the metal buckle also shall be installed in the middle position of busbar.
5. The head of manual tensioner must hold against the buckle then tense the ferromagnetic ribbon, make sure that the sensor is tied on measured conductor tightly. Finally, press the metal buckle.
6. Cut off the remaining ribbon with metal scissors
7. Roll up the tail

External probe (only for STX303 & STX313)

1. There are two methods to install the ring terminals, as below.
2. Open the rubber cover and then insert the connector of cable into sensor body
