Introduction

Every device that converts the physical world into digital data is a transmitter. However, every physical magnitude has its own unique challenges and measurement techniques. Let's discover the working principles of temperature, pressure, and level transmitters most commonly encountered in factories and why they are critical.

1. Temperature Transmitters

Temperature is the most monitored parameter of industrial processes. They usually convert weak signals coming from RTD (Pt100/Pt1000) or Thermocouple sensors into a standard output.

  • Application Area: Ovens, food processing lines, chemical reactors.
  • Why Important?: If weak mV signals are not converted to 4-20mA or digital data with a transmitter, the measurement error reaches huge dimensions as the cable distance increases.

2. Pressure Transmitters

They measure the pressure of liquids or gases and transfer it to the control system.

  • Application Area: Hydraulic systems, compressor lines, vacuum processes.
  • Technical Detail: The sampling rate of the transmitter (for example, 1000 Hz like the GDT Series) is of critical importance to capture high-speed changes.

3. Level Transmitters

They are used to measure the amount of liquid or solid materials in tanks.

  • Types: Ultrasonic (non-contact), hydrostatic (pressure-based), or level measurement with loadcell-based weighing.
  • Product Placement: In hygienic applications such as milk tanks, load cells placed under the tank and the Milk Tank Control Unit processing this data provide the most precise level information.

Common Denominator of Transmitters: Signal Conversion

Whether you measure temperature or pressure, a unity of "language" is needed for all this data to reach PLC or SCADA. This is where Amazeng's universal data collection solutions come into play.

  • GDT Digital Transmitter: It is not bound to only one type of sensor; it accepts 4-20mA, 0-10V, or mV/V (loadcell/pressure) signals and converts them into smart Modbus data.
  • ZMA Data Acquisition: It allows you to collect data from all these different transmitter types in your factory in a single center with 24-bit resolution.

Conclusion

Industrial transmitters are the invisible heroes of modern production. Choosing the right type and a high-quality data collection interface for every process ensures the longevity of your system.
