The OM-2628 IC probe features
the integrated circuit transducer
AD592CN. This IC solid state sensor is a two
terminal monolithic integrated
circuit temperature transducer
that provides an output current
proportional to absolute
temperature. For a wide range
of supply voltages the transducer
acts as a high impedance
temperature dependent current
source of 1 µA/K. Improved design
and laser wafer trimming of the
IC’s thin film resistors allows the
AD592CN solid state sensor to achieve absolute
accuracy levels and nonlinearity
errors previously unattainable at
a comparable price.
The OM-2628 probe can
be employed in applications
between -25 and 105°C
(-13 to 221°F) where conventional
temperature sensors (i.e.,
thermistor, RTD, thermocouple,
diode) are currently being used.
Expensive linearization circuitry,
precision voltage references,
bridge components, resistance
measuring circuitry and cold
junction compensation are not
required with the OM-2628 probe.
The OM-2628 solid state sensor is particularly useful
in remote sensing applications,
the AD592CN is immune to
voltage drops and voltage noise
over long lines due to its high
impedance current output.
