Explosion Proof Pressure Sensor in Kuwait | Air Pressure Sensors
The EXNT-8292 ATEX Air Pressure Sensor provides accurate relative-pressure measurement for compressed air, industrial gases, hydrogen, hydraulic fluids, and compatible process media in hazardous environments. As a dependable Explosion Proof Pressure Sensor in Kuwait, it supports oil and gas facilities, refineries, petrochemical plants, compressor stations, industrial HVAC systems, pneumatic networks, refrigeration plants, shipbuilding, and mining applications.
The sensor uses thin-film-on-steel measuring technology, which provides strong long-term stability, fast pressure response, and resistance to demanding process temperatures. Available measuring ranges extend from 0–0.4 bar up to 0–2,000 bar, covering low-pressure air systems as well as high-pressure hydraulic and gas applications.
The EXNT-8292 provides a standard two-wire 4–20 mA output for connection to PLCs, pressure indicators, controllers, SCADA platforms, data loggers, and Building Management Systems. It carries ATEX, IECEx, and UKEX certification for explosive gas, combustible-dust, and mining environments. Approved configurations support Zones 0, 1, and 2 for gas, Zones 20, 21, and 22 for dust, and underground mining applications.
Atex Hub supplies ATEX Pressure Sensors across Kuwait, the UAE, Saudi Arabia, Qatar, Oman, Bahrain, Europe, Africa, and worldwide for hazardous-area air-pressure, gas-pressure, hydraulic, refrigeration, and industrial automation projects.
What Is an EXNT-8292 ATEX Air Pressure Sensor?
The EXNT-8292 is an intrinsically safe industrial pressure transmitter designed to measure relative pressure in hazardous locations.
Relative pressure, also called gauge pressure, measures pressure in comparison with the surrounding atmospheric pressure. This makes the sensor suitable for monitoring compressed-air lines, gas systems, pumps, compressors, refrigeration circuits, hydraulic machinery, and pressure vessels.
The process medium enters through the sensor’s pressure connection and acts on a stainless-steel measuring element. The transmitter then converts the measured pressure into a proportional 4–20 mA electrical signal.
A typical measuring loop operates as follows:
- 4 mA represents the lower end of the selected pressure range.
- 20 mA represents the upper end of the selected pressure range.
- Intermediate current values represent pressures between the minimum and maximum limits.
For example, a sensor calibrated from 0 to 10 bar produces approximately 4 mA at 0 bar and 20 mA at 10 bar.
The EXNT-8292 can connect to:
- PLC analogue input modules
- Digital pressure indicators
- Industrial controllers
- SCADA systems
- Building Management Systems
- Remote telemetry units
- Data acquisition systems
- Alarm and shutdown panels
- Compressor-control systems
- Pump-control systems
Its intrinsically safe design limits the electrical and thermal energy available in the field circuit. When installed with a compatible Ex i barrier or galvanic isolator, it can provide pressure measurement without creating an ignition-capable spark or thermal effect under the approved conditions.

How Does the ATEX Air Pressure Sensor Work?
The ATEX Air Pressure Sensor uses a stainless-steel measuring element with a thin-film strain-gauge structure.
When air, gas, or liquid pressure enters the process connection, it causes a very small deformation in the sensor diaphragm. The thin-film measuring elements detect this strain and produce a corresponding electrical signal.
The transmitter’s internal electronics then:
- Measure the strain generated by process pressure.
- Compensate for temperature-related changes.
- Linearise the sensor response.
- Scale the signal according to the selected pressure range.
- Produce a standard 4–20 mA current output.
The pressure signal can help an automation system:
- Start or stop an air compressor
- Control a pneumatic valve
- Monitor receiver-tank pressure
- Detect low compressed-air pressure
- Trigger a high-pressure alarm
- Control a refrigeration compressor
- Monitor hydraulic pump discharge
- Protect a pressure vessel
- Record pressure trends
- Initiate an emergency shutdown
Because the transmitter uses a two-wire current loop, the same wiring carries both the electrical supply and the pressure-measurement signal.
For hazardous-area installations, the measuring circuit normally includes:
- EXNT-8292 pressure transmitter
- Certified intrinsic-safety barrier
- Galvanic isolator
- Compatible PLC or indicator input
- Approved instrumentation cable
- Correct loop-resistance calculation
- Proper cable segregation
- Earthing and bonding
- Hazardous-area loop documentation
