AUTEX 150 PSI Pressure Transducer
The AUTEX 150 PSI model provides a higher 0-150 PSI range while preserving the celebrated 0.5V–4.5V output and 5V DC operation. Its construction uses top-tier 316 stainless steel and high-temperature plastics to endure demanding environments. With a focus on precision, the sensor offers a small output error of ±1.0% FS and strong sensitivity, supporting accurate readings for water and other media in industrial settings. The broader range makes it a good fit for systems that experience transient pressure spikes or higher baseline pressures.
Flylin 30 PSI Pressure Transducer
Flylin’s pressure transducer for water systems presents a 0-30 PSI range with a 1/8″ NPT connection and a 0.5V–4.5V linear voltage output. The unit emphasizes high precision with ±2% FS small output error and a full temperature range, complemented by voltage protection features to guard against surges. Its stainless steel body contributes to robust durability, making it suitable for water tanks, hydraulic lines, and other low-pressure applications where compact design and reliable sensing are essential. It combines practical range with dependable performance for smaller-scale water monitoring tasks.
Buying Guide: Key Purchase Considerations
- Pressure range: Select a range that covers your operating conditions with some headroom to account for spikes and transients. If in doubt, choose a model with a wider range than your maximum expected pressure.
- Output type: Most options use a linear 0.5V–4.5V output compatible with common data loggers and microcontrollers. Confirm your readout device supports this range and voltage level.
- Thread and mounting: Ensure the thread size matches your plumbing or manifold (1/8″ – 27 NPT or similar). Consider space constraints and whether adapters are needed for installation.
- Materials and media compatibility: Stainless steel bodies with ceramic pressure plates provide durability and resistance to corrosion, making them suitable for water, oil, and other fluids. Verify compatibility with your media.
- Accuracy and stability: Look for specifications such as ±1.0% FS or ±2% FS and a full temperature range to gauge reliability in varying environments. Damping features help mitigate abrupt pressure changes.
- Durability and environmental tolerance: For field installations, choose devices with robust housings and low susceptibility to shock or vibration. Some sensors highlight resistance to instantaneous impact.
- Power requirements: Most devices run on 5V DC. Ensure your power supply and wiring can consistently deliver the required voltage without fluctuations that could affect readings.
- Media density and temperature: Some models emphasize wide temperature ranges and compatibility with water, air, and fuel. Consider whether your application will encounter extreme temperatures or aggressive fluids.
- Maintenance and service life: Stainless steel and ceramic components contribute to longevity. Review any maintenance requirements or calibration needs to sustain accuracy over time.
In summary, the listed options provide a spectrum from compact 30 PSI sensors for low-pressure water lines to mid-range 150–200 PSI transducers for more demanding systems. When selecting, align the pressure range, thread compatibility, and output format with your control hardware, while prioritizing materials and build quality that match your fluid environment.
