Stainless construction supports corrosion resistance and durability in household and industrial water applications.
AUTEX 100 PSI Pressure Transducer
Brand: AUTEX. Features include 0-100 PSI range with a 0.5V-4.5V output (5V DC supply). Fabricated from 316 stainless steel and high-temperature plastics, this model emphasizes robust construction for water, oil, and air systems. The sensor delivers a ±1.0% FS accuracy over a full temperature range, with strong emphasis on stability and repeatability, making it a reliable choice for water-based monitoring in both residential and industrial contexts.
LEFOO T2000 0-100 PSI Transmitter
Brand: LEFOO. This model provides a 0-100 PSI range with 4-20mA output and is powered by 8-36V DC. It uses a G1/4″ male connection and is suitable for measuring pressure in gas, water, and oil media. With a compact Hirschmann connector and a fast response time of 10 ms, it minimizes signal lag in dynamic water systems, making it suitable for real-time monitoring and control.
Hilitand Psi 0-1MPA Transmitter
Brand: Hilitand. This transmitter covers a broad 0-1 MPa range (approximately 0-145 PSI) and provides a 4-20mA current output. It’s built for water, gas, and oil measurement scenarios, featuring a smooth installation with G1/4″ connection and a robust build intended for reliable operation across varying temperature conditions. The product emphasizes stable performance and accuracy in water-related sensing tasks, particularly where higher pressure ranges are encountered.
Buying Guide: Key Purchase Considerations
- Output Type: Decide between voltage (0.5V-4.5V, 0-5V) and current (4-20mA) outputs based on your data acquisition system. Voltage outputs are easy to interface with ADC inputs; current outputs are better for long cable runs and electrically noisy environments.
- Pressure Range: Match the transmitter’s range to your system’s typical pressure. Over-specification can waste cost and reduce resolution; under-specification may saturate readings during peak pressure events.
- Medium Compatibility: For water systems, ensure the sensor material (e.g., 316 stainless steel) resists corrosion and is compatible with the intended liquid or gas environment.
- Electrical Power: Check supply voltage requirements (commonly 5V DC or 8-36V DC). Confirm available power and wiring constraints in your installation.
- Accuracy and Temperature Stability: Look for specifications like ±1.0% FS or better and a broad operating temperature range to ensure consistent readings in varying climate or industrial conditions.
- Mechanical Fit: Verify thread size (1/8″ NPT, G1/4″), connection type, and mounting orientation. Correct fittings prevent leaks and ensure reliable sensor alignment.
- Durability: For water and outdoor applications, choose sensors with stainless steel bodies, robust seals, and damping features to handle transient pressures and vibrations.
- Maintenance & Calibration: Consider devices with user-calibration capabilities or accessible calibration references to maintain accuracy over time.
- Installation Context: If the system involves rapid pressure fluctuations or pulsatile flow, prioritize models with fast response times and low hysteresis to capture dynamic changes accurately.
When selecting a pressure transmitter for water, balancing accuracy, durability, and compatibility with your data collection or control system is essential. The options above provide a range of voltage and current outputs, various pressure ranges, and strong water-suitability features to fit a variety of applications from domestic to industrial settings.
