Simple Temperature Controller Adjust R2 for 2. Inside the datasheet you can read information such as temperature sensor, range, temperature, ambient temperature, and precision temperature datasneet. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Information furnished is believed to be accurate and reliable. Reverse Voltage Change Figure 2.
Unlike other sensors, the LM has a linear output. Not recommended for new designs. Glue or cement the device to a surface and the temperature should be within about 0. Remove short across thermocouple. Many explanation regarding sensors, compensation, thermocouple, and output voltage are described inside this datasheet. Calibrated Error Figure 3. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof.
A pot connected across the LM with the arm tied to the adjustment terminal as shown in Figure 12 allows a 1-point calibration of the sensor that corrects for inaccuracy over the full temperature range. To lessen the affect of airflow, ensure that the wiring to the LM leads and wires connected to the leads is held at the same temperature as the surface temperature that is targeted for measurement.
Accuracy measurements are made in a well-stirred oil bath.
Efforts are underway to better integrate information from third parties. However, STMicroelectronics assumes no responsibility for the. For other conditions, self heating must be considered. This datasheet contains information related to package information, voltage, cold junction compensation, calibration, precision temperature s Efficient temperature transfer assumes that the ambient air temperature is almost the same as the surface temperature where the LM leads are attached.
For other conditions, self heating must be considered. Inside this datasheet the reader can find info related to ratings, precision temperature sensors, dynamic impedance, diagram, output voltage, Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Select R3 and R4 for datasjeet type 2. Adjust R2 for voltage across R4 corresponding to thermocouple. Operating output voltage change with current.

If the sensor is used in an ambient where the thermal resistance is constant, self-heating errors can be calibrated out. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which datasheeet dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions.
This publication supersedes and replaces all information. The Operating Output Voltage Change with Current specification can be used to calculate the additional error which could be up to 1 K maximum from the LMA, for example.
