TST300v2_R1.6 – December 2018
1.
Short description
TST300
v2
(successor of TST300) is a high accuracy temperature sensor with an RS-485
interface. The device doesn’t need external power supply, it is powered through the interface.
The temperature sensor integrates a band-gap temperature sensor element plus signals
processing and provides a fully calibrated digital output. The temperature sensors are factory-
calibrated. The calibration data is stored in the non-volatile memory. This ensures fully
interchangeable of the sensors without any extra efforts.
The sensor is delivered with one meter standard patch cable with RJ45 connectors. A 19” rack
mount kit can be ordered separately.
2. Features
• RS-485 interface carrying up to 32 nods;
• LED indicator for status of communication;
• Changeable bitrate and another communication parameters;
• Firmware update via the interface.
3. Applications
• Server room and data centers temperature monitoring and logging.
• High precision temperature monitoring and logging for food and drug storages.
• Environmental quality monitoring and assessment.
• Temperature monitoring in building management systems.
