The invention relates to a temperature guard sensor unit, which is to be connected as part of a temperature supervision system used to supervise the temperature of desired objects to prevent a fire and to issue an alarm of a dangerous situation. The sensor unit (1) includes one or more remote thermal sensors (2) and an optic module (3) defining an observation area, through which the remote thermal sensor monitors the temperature of the desired objects. The optic module (3) is interchangeably attached to the sensor unit (1), wherein optic modules provided with observation areas differing from one another are arranged to be optionally attached to the same sensor unit (1). In this case, the same sensor unit is suitable for different installation sites and different objects to be supervised, when the sensor unit is provided with an optic module (3) suitable for observing the object to be supervised from its installation site. |
