產(chǎn)品描述
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.
