Pressure Transmitter 4-20mA
Pressure Transmitter 4-20mA is a type of sensor used to measure pressure in various systems, converting the pressure value into a standard 4-20mA electrical signal. This signal is commonly used in industrial and control systems for monitoring and controlling processes.
Overview
Features:
Range: The pressure range of the transmitter is typically customized based on the application. Common ranges include:
0-100 psi
0-10 bar
0-1000 kPa
0-7000 psi (for high-pressure systems)
Output Signal: The transmitter converts the measured pressure into a proportional current signal. The 4mA represents the lower end of the pressure range, while 20mA represents the upper end. This 4-20mA signal is resistant to signal degradation over long distances and is less susceptible to electrical noise.
Accuracy: Pressure transmitters usually offer high accuracy with a typical error range of ±0.1% to ±0.5% of the full scale. Some high-precision models can go down to ±0.05%.
Power Supply: These transmitters generally require an external power supply, usually 24V DC, although the exact requirement can vary by model.
