4800LC THERMISTOR LINEARIZING CIRCUIT

The MSI 4800LC converts the non-linear resistive response of thermistors to a linear output.  The output is a TTL or RS-232 serial digital data stream.  Now engineers can reduce the design cycle while taking advantage of highly-accurate and stable MSI Precision thermistors.

FEATURES:

  • Automatically calculates a linear output

  • Simplifies design and reduces the design cycle

  • Uses minimal board real estate

  • Relieves microprocessor demand

  • Includes serial TTL and RS-232 output

  • Low power consumption allows battery operation

  • Resolution of 0.01C

  • Circuit accuracy 0.1C from 0 to 100C
    (system accuracy depends upon thermistor)

  • No calibration required

The MSI 4800LC Thermistor Linearizing Circuit offers the Design Engineer new options in precision temperature measurement.  No more cold junction compensation, no more low sensitivity, no more settling for less accuracy than you need, no more concern for non-linear output.  MSI engineers, with years of experience designing circuits for thermistor applications, have designed one package that allows the use of highly sensitive thermistors with minimal design effort.  The MSI 4800LC requires no calibration and can match with a variety of thermistors to meet specific temperature measurement applications.
