Temperature control units
TMD are used measure and control the temperature levels and efficiency of electric
machines, power transformers, motors, etc.
The temperature is measured by four PT100 type sensors. Each measuring channel has
two programmable alarm thresholds which trip two output relays to remotely signal that
a critical temperature has been reached.
The measured values and any alarm conditions are shown on the dual 3-digit display on the
front of the device, which also has five programming keys for configuring its operation.
The control unit is also able to store in memory maximum values and a log of all trip-events.
