Atmodule RS485/RS232 Transmitter
Industrial Sensor Interface Module

General Description

The Atmos industrial transmitter module is a complete digital transmitter solution. The module accepts inputs from uncompensated bridge-type sensors and produces calibrated, temperature-compensated pressure and temperature values.

Features

• Pulsed or continuous sensor excitation
• Digitization of sensor differential output
• Digitization of bridge impedance for temperature feedback
• Digital calibration and temperature correction through high order multinomials
• RS485/RS232 output
• High-resolution sigma-delta type A/D converter
• ESD protected inputs and outputs
• EMI/RFI filtered inputs and outputs
• User selectable baud rate
• Corrected pressure output
• Corrected temperature output
• End user gains and offset values (separate from the correction multinomial)
• Module size 1.2 x 2.2 inches

Applications

• Pressure sensors
• Bridge interface
• Industrial transmitters
