Pt100
The Pt100 sensor offers these features:
• Continuous monitoring of the motor temperature
• Protection against too high motor temperature.
Protecting the motor against too high motor
temperature is the simplest and cheapest way of
avoiding that motor lifetime is reduced. Pt100 ensures
that operating conditions are not exceeded and
indicates when it is time for service of the motor.
Monitoring and protection by means of Pt100 require
the following parts:
• Pt100 sensor
• Relay, type PR 5714
•Cable.
The PR 5714 relay is fitted with a Pt100 module. For
both relays the following temperature limits are preset
on delivery:
• 60 °C (140 °F) warning limit
• 75 °C (167 °F) stop limit.
