Working Principle
Receives a raw electrical signal from a primary sensor, conditions and amplifies it, applies linearization algorithms, and outputs a highly accurate, standardized signal to the control system.
Installation Requirements
- Must be installed away from high-voltage interference sources.
- Shielded cables are required for signal connections.
- Proper grounding of the instrument chassis is mandatory.
Precautions for Use
- Calibrate the transmitter according to the manufacturer’s specifications before deployment.
- Ensure the loop resistance is within acceptable limits for 4-20 mA operation.
- Avoid exposing the module to extreme mechanical shock or vibration.
