TS-02 elbag discontinued temperature monitoring unit

The ELBAG TS-02 is a multi-channel industrial temperature monitoring and protection relay unit designed for continuous supervision of electrical and electromechanical equipment such as transformers, motors, and generators. It is widely used in medium-voltage and high-voltage distribution systems to ensure reliable thermal protection through real-time temperature acquisition and relay-based alarm/trip functions.

The device integrates multiple sensing technologies, including PTC thermistors (DIN 44081/82 compliant) and PT100 resistance temperature detectors, enabling both protective and precision temperature monitoring within a single platform.

Q1: What is the multi-channel thermistor-based temperature surveillance topology implemented within the TS-02 under ELBAG industrial monitoring architecture?

A:
The TS-02 is a multi-loop temperature monitoring and protection relay unit designed to supervise industrial equipment using PTC thermistors (Kaltleiter) and PT100 sensors. The TS-02 integrates multiple measurement circuits (“Tx”, “T>”, “T>>”) to provide hierarchical thermal supervision, enabling graded alarm and trip functions in transformer, motor, and generator protection systems.

Q2: How does the TS-02 implement real-time thermistor resistance threshold discrimination in its temperature evaluation algorithm?

A:
The TS-02 operates by continuously evaluating PTC resistance thresholds in the kilo-ohm range, where temperature transitions are translated into discrete switching states. When resistance exceeds calibrated thresholds, the TS-02 activates corresponding relay outputs, ensuring deterministic temperature escalation detection and fault signaling.

Q3: What is the functional significance of the multi-stage relay logic architecture embedded in the TS-02 (T>, T>>, Tx) monitoring channels?

A:
The TS-02 employs a three-tier protection logic structure:

• T> (pre-alarm stage)
• T>> (critical overtemperature shutdown stage)
• Tx (auxiliary / composite monitoring circuit)

This hierarchical architecture enables progressive thermal escalation handling, allowing early warning, controlled load reduction, and final emergency disconnection depending on thermal severity.

Q4: How does the TS-02 implement self-calibrating long-term stability mechanisms through periodic diagnostic cycling?

A:
The TS-02 performs an automatic self-test cycle every 720 hours, during which Relay 4 is energized for approximately 10 minutes. This internal diagnostic routine validates measurement integrity, ensuring long-term drift compensation and maintaining measurement stability without manual recalibration.

Q5: In what manner does the TS-02 detect wiring anomalies such as open-circuit or short-circuit conditions in its sensing network?

A:
The TS-02 continuously monitors sensor loop integrity in all measurement channels. If a wire break or short circuit is detected in the “temp >”, “temp >>”, or “Tx” circuits, the system immediately triggers:

• Fault indication on the 7-segment display
• Activation of fault relay output (Relay 4)

This ensures rapid detection of sensor network degradation.
