What is a Pressure Transmitter?
A pressure transmitter is an instrument used to measure pressure in gases, liquids, or steam. It converts physical pressure into an electrical signal, which can then be transmitted to control systems such as SCADA, PLC, or DCS for monitoring and control purposes.
Pressure transmitters are widely used for:
- Monitoring fluid pressure in pipelines.
- Controlling process safety systems.
- Ensuring compliance with industrial standards.
- Improving efficiency in energy consumption.
The RDLY Series Pressure Transmitter is one such advanced device, designed with accuracy, durability, and adaptability in mind.

Working Principle of RDLY Series Pressure Transmitter
The RDLY Series uses a sensing diaphragm that deforms when exposed to pressure. This deformation is detected by a sensor element (usually piezoresistive, capacitive, or strain gauge-based). The signal is then amplified, processed, and converted into an electrical output that represents the applied pressure.
This processed signal can be transmitted to:
- PLC systems for process control.
- SCADA/DCS systems for real-time monitoring.
- Data loggers for historical analysis.
The simplicity and accuracy of this working principle make the RDLY Series one of the most dependable devices in industrial instrumentation.
