FST Series LM35 Precision Centigrade Temperature Sensors

Product catalog summary

Overview: The LM35 series are precision integrated-circuit temperature sensors with an output voltage linearly proportional to the Celsius temperature. Unlike sensors calibrated in Kelvin, the LM35 provides direct Celsius readings without requiring additional calculations.

Typical Applications: The LM35 sensors are suitable for HVAC systems, refrigerators, ice houses, libraries, portable equipment, and industrial equipment.

Features:

Calibrated directly in Celsius with a linear scale factor of +10.0 mV/°C.
Accuracy of 0.5°C at 25°C, with a full range from −55°C to +150°C.
Low cost due to wafer-level trimming and suitable for remote applications.
Operates from 4 to 30 volts with less than 60 μA current drain.
Low self-heating of 0.08°C in still air and low impedance output.

Technical Data:

Power Supply: 4 - 30V
Measurement Range: Varies by model, from −55°C to +150°C.
Accuracy: ±0.5°C at 25°C, with variations at maximum and minimum temperatures.
Quiescent Current: Ranges from 116 μA to 161 μA depending on the model.
Output Current: 10mA
Sensor Gain: 10±0.1 mV/°C to 10±0.2 mV/°C

FST Series LM35 Precision Centigrade Temperature Sensors-1

FST Series LM35 Precision Centigrade Temperature Sensors The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. Typical Applications • HVAC, • Refrigerator • Ice house • Library • Portable equipment • Industrial equipment Features Calibrated directly in ° Celsius (Centigrade) • Linear + 10.0 mV/°C scale factor • 0.5°C accuracy guarantee able (at +25°C) • Rated for full -55° to +150°C range • Suitable for remote applications • Low cost due to wafer-level trimming • Operates from 4 to 30 volts • Less than 60 pA current drain • Low self-heating, 0.08°C in still air • Nonlinearity only ±V4°C typical • Low impedance output, 0.1 W for 1 mA load Note : 1.
