What is a Pressure Transmitter? WIKA Measurement Guide

Reliable measurement in industrial processes is critical for production quality and operational safety. A pressure transmitter measures liquid or gas pressure and converts it into an electrical signal.

What is a Pressure Transmitter?

A pressure transmitter converts measured pressure into a standard output signal (4-20 mA, 0-10 V) transmitted to PLC, SCADA or control systems. Benefits: • Continuous process pressure monitoring • Alarm and control scenarios • Production quality maintenance • Early fault detection

Applications

• Chemical, petrochemical, pharmaceutical and food plants • Pump and compressor systems • Water and wastewater applications • Hydraulic and pneumatic systems • HVAC and building automation

Why Choose WIKA?

• High measurement accuracy • Long service life • Wide product range • Industrial standards compliance • Models for harsh environments

Selection Criteria

1. Pressure range
2. Process medium (gas, liquid, steam, aggressive chemicals)
3. Output signal (4-20 mA most common)
4. Connection type
5. Environmental conditions
6. Hygienic/flush diaphragm requirements

WIKA Models

A-10: General industrial applications S-11: Flush diaphragm for viscous and hygienic processes IS-3: Demanding industrial conditions E-10/E-11: Alternative process solutions

FAQ

What does a pressure transmitter do? Measures pressure and converts it into an electrical signal for automation systems.

What is the difference between A-10 and S-11? A-10 is for general industrial use, S-11 has flush diaphragm for viscous or hygienic processes.

Is a pressure transmitter the same as a pressure gauge? No. A gauge shows local reading, a transmitter sends data to the control system.
