This sensor targets oil, fuel, air, and water applications and provides reliable performance across varying temperatures and media compatibility.
FUSCH 200 PSI Pressure Transducer

With a 0–200 PSI range, this FUSCH transducer maintains high accuracy through a 0.5V–4.5V output and 5V power supply. Built from 316 stainless steel and ceramic pressure plates, it offers low output error (±1.0% FS) and supports operation across a full temperature range. It is designed to handle oil, fuel, water, and air, making it suitable for demanding automotive and industrial fluid systems.
Flylin Pressure Transducer 5 PSI

The Flylin sensor targets low-pressure scenarios with a 0–5 PSI range and 1/8″ NPT thread. It provides the standard 0.5V–4.5V output, suitable for oil, fuel, air, water, and related media. It includes surge voltage protection to safeguard electronics, and the 316 stainless steel body offers corrosion resistance in harsh environments.
DriSentri 0–100 Psi Sensor

The DriSentri unit is built from 316 stainless steel and designed for high-temperature and corrosion resistance. It provides 0.5V–4.5V output across a 0–100 PSI range, operating from 5–16V supply, with a 1/8″ NPT thread. The sensor is IP65-rated for protection against dust and water ingress, making it well-suited for automotive, fuel, and industrial environments where reliability is critical.
Buying Guide: Key Considerations For In Line Pressure Transducers
When selecting an in line pressure transducer, several factors influence performance, compatibility, and cost. This guide compares essential considerations and practical trade-offs to help you choose the right sensor for your system.
- Pressure range and accuracy: Determine your operating range (e.g., 0–100 PSI, 0–150 PSI) and required accuracy. Look for sensors with low nonlinearity, hysteresis, and repeatability to minimize measurement error in critical applications.
- Output type and electronics interface: Most of these sensors use a 0.5V–4.5V analog output suitable for direct connection to microcontrollers or analog data loggers. Ensure compatibility with your control system or PLC. Some models also offer 4–20mA outputs for industrial loops.
- Materials and media compatibility: Stainless steel bodies (316) and ceramic pressure plates provide durability and chemical resistance. Confirm media compatibility (oil, fuel, water, air) and operating temperature to avoid corrosion or degraded performance.
- Electrical requirements and protection: Check power supply (commonly 5V DC) and any protective features such as surge protection. Consider IP ratings for environmental exposure in outdoor or wet locations.
- Thread size and installation: Most sensors use 1/8″ NPT threads for standard installation. Verify thread compatibility with your system, mounting options, and sealing requirements to prevent leaks.
- Durability and environmental conditions: Applications in engines, fuel systems, or industrial machinery may demand vibration resistance, damping features, and robust housing to reduce measurement drift.
- Maintenance and service life: Consider cycle life (e.g., up to 500,000 activations for some models) and ease of replacement to minimize downtime in critical systems.
- Cost of ownership: While all listed sensors share common features, factors such as precision, temperature range, and media compatibility influence longer-term reliability and maintenance costs.
In summary, for oil, fuel, air, and water monitoring, in line pressure transducers with a 0.5V–4.5V output, 316 stainless steel bodies, and 1/8″ NPT threads are widely suitable. Align the sensor’s pressure range, output interface, and environmental protections with your application to achieve reliable, long-term performance.
