Pressure Sensors

Bestech Australia is a leading supplier of pressure sensors in Australia, offering advanced solutions for industrial, environmental, and research applications.

Our pressure sensors measure the pressure of gases or liquids with exceptional precision, converting it into an electrical signal for use in monitoring, control, and automation systems.

With over 23 years of engineering experience, Bestech offers reliable and high-accuracy pressure measurement technology designed for long-term performance in the most demanding Australian conditions.

What Are Pressure Sensors?

A pressure sensor measures the force exerted by a gas or liquid. When configured to standardize and transmit signals, it may also be referred to as a pressure transducer or pressure transmitter. These measurements are converted into electrical signals that can be transmitted, displayed, or processed by control systems to ensure safe and efficient operation.

Pressure is typically measured in pascals (Pa), bar, atmospheres (atm), or pounds per square inch (psi). Depending on the application, sensors may measure absolute pressure, gauge pressure, or differential pressure.

Types of Pressure Sensors

Bestech offers one of the most comprehensive selections of pressure sensors in Australia. Each type is engineered for specific use cases and environments, ensuring precision, durability, and compliance with industry standards.

1. Industrial Pressure Transducers & Transmitters

Designed for hydraulic, pneumatic, and process control systems, these sensors convert pressure into accurate analog or digital signals. Ideal for manufacturing, automation, and industrial process control.

2. Differential & Low-Pressure Sensors

High-sensitivity sensors that measure pressure differences between two points, commonly used in HVAC systems, air filtration units, and cleanroom monitoring.

3. Submersible Pressure Sensors

Waterproof pressure sensors for level and depth measurement in water, wastewater, and environmental monitoring. Engineered with durable stainless-steel housings for long-term stability.

4. Hydrogen Pressure Sensors

Specialised hydrogen-compatible sensors designed for fuel cell testing, renewable energy, and gas handling systems. Built with materials resistant to hydrogen embrittlement and leakage.

5. Miniature & OEM Pressure Sensors

Compact and lightweight sensors for medical devices, aerospace systems, and OEM integration, offering precise measurement in space-constrained designs.

6. Melt & High-Temperature Pressure Transducers

Rugged sensors built to withstand extreme pressure and temperature in plastic extrusion, injection moulding, and die-casting environments.

7. Digital Pressure Gauges & Switches

Digital gauges provide clear on-screen readings, while pressure switches automatically trigger safety or control functions when limits are reached.

8. IECEx-Certified Pressure Sensors

Certified for use in hazardous and explosive areas, these intrinsically safe pressure sensors meet IECEx and ATEX international standards, making them ideal for oil, gas, and mining industries.

Frequently Asked Questions (FAQs)

Q1. What’s the difference between a pressure sensor, transducer, and transmitter?

A pressure sensor detects the applied pressure and produces a raw electrical signal proportional to that pressure.

A pressure transducer converts the detected pressure into a standardized electrical output, such as a voltage or current.

A pressure transmitter further conditions and amplifies this signal, often converting it into a 4–20 mA or 0–10 V output, for reliable transmission over long distances to control systems or displays.

Q2. How accurate are Bestech’s pressure sensors?

Our sensors offer accuracy from ±0.05% to ±0.5% of full scale, depending on model and application.

Q3. Can Bestech pressure sensors be used in hazardous areas?

Yes. We provide IECEx-certified and intrinsically safe pressure sensors compliant with Australian standards for explosive environments.

Q4. Do you provide calibration and maintenance support?

Absolutely. Bestech offers in-house calibration, installation guidance, and lifetime technical support for all supplied products.

Q5. Can I integrate Bestech pressure sensors into IoT systems?

Yes. Many of our models support IoT and SCADA connectivity, enabling remote monitoring and data logging via cloud platforms.
