Distillation
Pump systems
Process control
Laboratory applications

Yokogawa, for example, provides dedicated absolute pressure transmitter models such as EJA310E and EJX310A.

4. 4-20mA Pressure Transmitter

The 4-20mA pressure transmitter remains one of the most common industrial pressure measurement solutions.

The transmitter converts pressure into a standard electrical signal:

4mA = Lower Range Value

20mA = Upper Range Value

The signal can be connected to:

PLCs
SCADA systems
DCS systems
RTUs
Process controllers
Data acquisition systems
Industrial monitoring systems

5. HART Pressure Transmitter

A HART pressure transmitter combines the conventional 4-20mA signal with digital communication.

This allows technicians to obtain additional information such as:

Configuration
Diagnostics
Measurement range
Device status

How to Select the Correct Pressure Transmitter

Choosing a pressure transmitter is more than simply selecting a pressure range.

Before ordering, confirm the following:

1. Pressure Type

Determine whether you require:

Gauge, absolute or differential pressure.

2. Measuring Range

For example:

0-1 bar
0-2.5 bar
0-6 bar
0-10 bar
0-16 bar
0-25 bar
0-40 bar
0-100 bar
0-250 bar
0-400 bar
0-600 bar

The actual range should be selected according to the operating pressure and required measurement accuracy.

3. Output Signal

Common options include:

4-20mA
4-20mA HART
0-10V
0-5V
IO-Link
Modbus
FOUNDATION Fieldbus
PROFIBUS PA
Wireless protocols

4. Process Connection

Common connections include:

1/4″ NPT
1/2″ NPT
G1/4
G1/2
DIN connections
Flanged connections
Tri-Clamp
Custom process connections

5. Wetted Materials

Consider whether the process medium is:

Water
Oil
Steam
Gas
Chemical
Slurry
Food product
Corrosive fluid

The diaphragm and wetted materials must be compatible with the process.

6. Process Temperature

High-temperature applications may require:

Remote diaphragm seals
Capillaries
Special diaphragms
High-temperature-rated transmitters

7. Hazardous Area Certification

For hazardous environments, specify the required certification, such as:

ATEX
IECEx
FM
CSA
Intrinsically Safe

8. Accuracy

Industrial pressure transmitters are available with different accuracy classes. Select accuracy according to the process requirements rather than simply choosing the highest specification.

Tips When Buying Pressure Transmitters in South Africa

Tip 1: Don’t select only by pressure range

A 0-10 bar transmitter may physically fit your application but still have the wrong output, connection, accuracy or wetted materials.

Tip 2: Check the existing instrument

Always record:

Manufacturer + Model + Serial Number + Range + Output + Process Connection

before ordering a replacement.

Tip 3: Confirm 4-20mA vs HART

A basic 4-20mA transmitter and a 4-20mA HART transmitter may look similar but provide different communication capabilities.

Tip 4: Check the PLC/SCADA system

Confirm that the transmitter output is compatible with the available PLC, RTU, DCS or SCADA input.

Tip 5: Check hazardous-area requirements

Mining, chemical and oil & gas installations may require specific certifications.

Tip 6: Consider the process medium

Water, steam, slurry and aggressive chemicals can require different diaphragm and wetted-material configurations.

Tip 7: Don’t overspecify unnecessarily

A higher-pressure range or accuracy specification does not automatically make an instrument better for your application.

Tip 8: Consider calibration

For critical process applications, specify calibration documentation and calibration requirements when requesting your quotation.

Frequently Asked Questions

What is a pressure transmitter?

A pressure transmitter is an industrial measurement device that measures pressure and converts it into an electrical output signal, commonly 4-20mA, for use by a PLC, SCADA, DCS or other control system.

What is the most common pressure transmitter output?

4-20mA is one of the most widely used industrial analogue outputs. HART communication is also commonly added to provide digital configuration and diagnostic information.

What is a 4-20mA pressure transmitter?

A 4-20mA pressure transmitter converts a measured pressure range into a proportional current signal. It can be connected to industrial control and monitoring systems.

What is a HART pressure transmitter?

A HART pressure transmitter uses digital HART communication together with the analogue 4-20mA signal. This allows additional configuration and diagnostic information to be communicated.

What is the difference between gauge and absolute pressure?

Gauge pressure is referenced to atmospheric pressure, while absolute pressure is referenced to an absolute vacuum.

What is a differential pressure transmitter?

A differential pressure transmitter measures the pressure difference between two pressure connections. It is commonly used for flow, level and filter monitoring.
