TST103

Product catalog summary

Short Description:
TST103 is a digital temperature sensor featuring a 1-Wire interface, eliminating the need for an external power supply as it is powered through the interface. It includes a band-gap temperature sensor element with signal processing, providing a fully calibrated digital output. The sensors are factory-calibrated with calibration data stored in non-volatile memory, ensuring interchangeability without additional effort. It comes with a one-meter cable and RJ11 connectors, with an optional 19” rack mount kit available.

Applications:

Temperature monitoring and logging in server rooms and data centers.
Monitoring for food and drug storage facilities.
Environmental quality monitoring and assessment.
Temperature monitoring for facilities like vineyards and greenhouses.

Technical Parameters:

Operating Range: –40 to 85 °C
Accuracy: ±0.5 °C from -10 to +85°C, ±2 °C from -40 to +85°C
Resolution: 0.1 °C
Supply Voltage: 3 to 5.5 VDC from 1-Wire interface
Max Consumption: 2 mA from 1-Wire interface
Ingress Protection: IP20
Dimensions: 85 x 35.1 x 23.5 mm
Connectors: Two RJ-11 in parallel

Installation:
The sensor uses a 1-Wire Bus, a registered trademark of Maxim Integrated Products, Inc. It is recommended to read Maxim's 1-Wire tips for optimal use. The pinout includes:

1-Wire GND: White/Brown, White/Green, White/Orange
1-Wire Data: Green
1-Wire +VDD: Orange, Brown

Use UTP/FTP cables and a daisy-chained (linear) topology for multiple sensors, keeping the total cable length up to 30 meters. A 'Star' topology is a last resort for up to 4 sensors with a total cable length of up to 10 meters.

Installation Tips:

Install sensors 1.2-1.4 m above the floor, away from heating and cooling sources.
Avoid installation next to windows to prevent solar radiation interference.
Ensure sufficient air circulation around the sensors.
Wall mount sensors with vent holes up/down for optimal air circulation.

TERACOMShort description TST103 is a digital temperature sensor with a 1-Wire 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 temperature sensor is delivered with one meter cable with RJ11 connectors. A 19" rack mount kit can be ordered separately. • Server room and data centers temperature monitoring and logging. • Temperature monitoring and logging for food and drug storages. • Environmental quality monitoring and assessment. • Temperature monitoring for facilities, vineyards, greenhouses, etc. Remark -10 to +85°C -40 to +85°C From 1-Wire interface From 1-Wire interface Parameter Value Units Can be used with following TERACOM controllers
