Introduction:
The AST282 family of temperature transmitter is suitable for Resistance Temperature Detectors (RTDs), thermocouples(TCs), resistance and voltage signal input through PC configuration, and that sensor input and signal output digital isolation, as well as high-resolution, high-precision, ultra-low power consumption
The product module uses 24-bit sigma-delta(Σ-Δ)analog-to-digital converters(ADCs), digital isolation (isolation voltage up to 2kV), to ensure the transmitter is stable in interference environment also using ultra-low power MCU with built-in cold junction compensation, to achieve signal filtering, amplification and linearization
The transmitter features wide measurement range and high accuracy, with silicone-rubber, or epoxy resin sealing structure, so it has good performance of shock resistance, resistance to wet, and anti-interference, which is suitable for bad industrial environment
Applications:

• Standard RTDs, TCs
• Ohm and mV signal
• 2-, 3-, and 4-Wire RTD input

Main Features:

• Electronic isolation
