Frequently Asked Questions (FAQ)
-
What’s the difference between 51400331-106 and -107?
The -107 variant adds a 0-10V output option, while -106 is 4-20mA only. -
Is it submersible?
Yes, IP67 allows temporary immersion (1m/30min). -
Can it measure vacuum?
No, this model is gauge pressure only (positive range). -
What’s the response time?
<1ms for step changes. -
Does it need a signal conditioner?
No – the 4-20mA output is PLC-ready. -
Is temperature compensation included?
Yes, -40°C to +125°C compensation is built-in. -
What’s the MTBF (Mean Time Between Failures)?
250,000 hours at 25°C. -
Can it handle pulsating pressures?
Yes, up to 10kHz dynamic pressure cycles. -
Is the Viton® seal compatible with diesel fuel?
Yes, but for prolonged exposure, specify FFKM seals (optional). -
How long is the warranty period?
The standard warranty is 1 years, subject to proper usage and conditions.
