Satel Detector Temperature Progr./Td-1

TD-1 is a programmable temperature detector that can handle two independent sensors: a built-in one and a connectable external one. It monitors the temperature within the -35°C to +60°C range and alerts when it goes beyond the minimum or maximum threshold value. It can also provide information about exceedingly rapid temperature changes, which may be useful for indicating a sudden warming of air in the cold store. Connecting a bistable switch instead of the external probe allows toggling between two sets of critical parameters of the internal sensor, such as for day and night.

The detector enclosure contains three buttons for programming the device, as well as a four-digit LCD screen that displays the current ambient temperature and the value read from the external probe. Error messages can also be displayed on the screen.

The TD-1 detector has a built-in piezoelectric transducer for audible signaling, a tamper switch, and two programmable relay outputs, which can be used for communication with the control panel or for controlling another device.
