- IP67 protection ensures reliable operation in wet or dusty conditions
- Wide -40°C to +120°C operating range suits extreme temperature applications
150 PSI Pressure Transducer
This 1/8 NPT stainless steel sensor converts 0 to 150 psi into a 0.5 to 4.5 V linear signal for data loggers and ECUs. It suits automotive fuel, oil, air and water systems where a compact IP67 transducer is required. The ceramic core delivers ±0.5 % FS accuracy across a -40 to +120 °C range.
Upgrade from mechanical gauges
Mechanical senders drift with vibration and temperature; this solid-state unit holds ±1.0 % FS total error including hysteresis and non-linearity. The jump is worth it when you need repeatable 0.5 V at zero pressure and 4.5 V at full scale without recalibration. Overload capacity of 2 to 4 times rated pressure protects against spikes.
12 V supply headroom
The transducer draws 20 mA and needs at least 6.5 V, so a 12 V vehicle rail provides ample margin. Long-term drift stays below 0.1 % FS per year, and shock resistance reaches 1000 g. It runs out of headroom if supply voltage drops near 6.5 V or if media attacks 316L stainless steel.

Questions about this item
What thread size does the 1/8 NPT sensor need for mounting?
The sensor uses a 1/8" NPT thread; match the port to this size for a proper seal.
Which wire colour carries the 0.5-4.5V signal during wiring?
The green wire is the signal output; red is +5V and black is ground.
How often should the ±0.5% FS accuracy be re-checked?
Long-term drift is under 0.1% FS per year, so annual verification is sufficient.
