NTK Extends its Portfolio with New EDPS Range

As the world’s leading ignition and sensor specialist, Niterra Australia announces the launch of its new Exhaust and Differential Pressure Sensor (EDPS) range.

NTK’s premier status in the industry is driven by its dedication to four competitive advantages – range, availability, tech support and OE standards. NTK has more than 40 years of expertise in the sensor industry and stands as Australia’s leading ignition and sensor supplier.

NTK expanded its comprehensive catalogue of sensors by releasing EDPS in March 2025. This latest addition to NTK’s sensor range highlights its unique offerings to the Australian aftermarket, quickly gaining popularity among distributors, workshops, and end-users.

The NTK EDPS range provides extensive vehicle coverage with:

• DIFFERENTIAL PRESSURE SENSORS (DPS)
• EXHAUST PRESSURE SENSORS (EPS)
• HIGH PRESSURE SENSORS (HPS)

What does an EDPS do?

• EDPS play a significant role in engine optimisation. They are required to provide engine control units (ECU) with the necessary information regarding the exhaust gas pressures and the filling level of the diesel particulate filter (DPF). The NTK EDPS range include differential pressure sensors (DPS), Exhaust Pressure Sensors (EPS) and High-Pressure Sensors (HPS). It provides comprehensive vehicle coverage. The sensors, moreover, are capable of being installed at a variety of different vehicle positions.
• The DPS gauges the pressure drop between two positions in the flow pattern. It is installed at different locations in the exhaust manifold (before/after the DPF, before/after the catalyst, before/after the turbocharger or before/after the EGR (exhaust gas recirculation) cooler). At one point, it regulates the low-pressure gas recirculation. At the other position. It observes the function of the DPF, while also reporting its charge status back to the ECU.
• The EPS measures the pressure and reports this information back to the ECU. It can be mounted at different positions in the exhaust system, for example before the DPF, before the turbocharger or after the turbocharger.
• The HPS measures the back pressure of the exhaust gases. It is installed either before the DPF, before the turbocharger, after the turbocharger, or after the EGR cooler. This information is sent to the ECU which uses it to monitor and protect the turbocharger unit. The monitoring of output air pressure prevents back pressure damage to the exhaust manifold. For EGR valves and EGR Coolers, the information is also used to adapt and control the exhaust gas recirculation rate – which is important in terms of adhering to the emissions standards.

Building on years of leadership in sensor technology for both vehicle manufacturers and the aftermarket, NTK’s addition of Exhaust and Differential Pressure Sensors (EDPS) completes its portfolio of anti-pollution products.
