Types of Transmitters

Types of Transmitters

Transmitters are available in two types: electronic and pneumatic. Both types send a standard signal that can be interpreted by devices within the control loop. In electronic transmitters, a 4–20 mA current signal is sent, while pneumatic transmitters send an air pressure signal of 3–15 PSI to electronic or pneumatic controllers.

Types of Instrumentation Transmitters

Transmitters can be categorized into several types based on their function and application:

• Pressure Transmitter
• Temperature Transmitter
• Humidity Transmitter
• Flow Transmitter (Fluid Flow Transmitter)
• Level Transmitter (Tank or Liquid Level Transmitter)
• Weight Transmitter
• Velocity Transmitter
• …etc.
