PicoBNC+ 14-bar Pressure Transducer with Foster Adaptor
Traditional pressure gauges do not provide technicians with a graphical representation of their measurements so they can’t show and / or record the pressure values and trends they observe during the test.
It follows that they can’t easily share their results with customers, colleagues or technical support and warranty teams. Nor can they come back to them when they need reference data in the future.
The new PQ334 PicoBNC+ 14-bar Pressure Transducer with Foster Adaptor fulfils these needs and additionally, offers all the PicoBNC+ ease-of-use benefits, such as not needing a battery, software probe recognition, and software probe range control.
The pack includes:
- PICO-TA393 PicoBNC+ 14-bar Pressure Transducer
- PICO-TA413 Foster Series 2 to ¼"NPT Adaptor
PicoBNC+™ PICO-TA393 and WPS500X Comparison
| Measurement | Conditions | Range in Bar | TA393 | WPS500X | Notes |
|---|---|---|---|---|---|
| Intake manifold pressure (naturally aspirated) | Cranking, Idle and WOT | -1 to 0 | Y | Y | - |
| Intake manifold pressure (turbo boosted) | Cranking, Idle and WOT | -1 to 3 | Y | Y | - |
| Exhaust pressure | Cranking, Idle and WOT | -0.5 to 0.5 | N | Y | - |
| Crankcase pressure (dip-stick tube) | Cranking, Idle and WOT | -0.5 to 0.5 | Y | Y | - |
| In-cylinder pressure | Cranking | Up to 25 bar and more in diesels | Limited petrol engines | Y | Covers about 75% of petrol vehicles |
| In-cylinder pressure | Idle | Up to 8 bar | Y | Y | Variable valve lift (e.g. Valvetronic, VVTI-L and Valvematic) should also be OK |
| In-cylinder pressure | WOT | Exceeds 35 bar sometimes | N | Y | - |
| Fuel rail pressure regulator pulsation | Idle | - | N | Y | - |
| Common rail diesel (solenoid) back leakage pulsation | Cranking | 0 to 1 | Y | Y | Must be used inline with back leakage pipework |
| Oil pressure | Cranking, Idle and WOT | 1 to 7 | Y | Y | - |
| DPF back pressure | Cranking, Idle and WOT | -0.5 to 1 | Y | Y | - |
| Negative priming fuel pressure diesel | Crank and start (deadhead pump) | -1 to 0.5 | Y | Y | - |
| Positive priming petrol and diesel | Cranking, Idle and WOT | 3.5 to 7 | Y | Y | - |
FAQs
Q: Will the TA393 PicoBNC+ 14-bar Pressure Transducer replace the WPS500X pressure sensor?
A: No – the WPS500X will still be sold. The WPS500X has greater measurement sensitivity and range and is suitable for a much wider range of applications. For example, in terms of range, theTA393 PicoBNC+ 14-bar Pressure Transducer can be used for in-cylinder pressure measurements on some vehicles, but not those with higher compression petrol or diesel engines.
In terms of sensitivity, the TA393 does not easily pick up smaller pressure changes such as those occurring with exhaust or crankcase pressure measurements. Due to these limitations, the TA393 PicoBNC+ 14-bar Pressure Transducer is best thought of as a limited-purpose but convenient gauge replacement pressure measurement probe.
Q: Why has this pressure sensor been released?
A: We have made this sensor available at a price level that makes it attractive as a limited-purpose pressure probe.
One application where this probe is particularly attractive is when a technician wants to measure pressure in two parts of a system at the same time: A less expensive second pressure probe allows him to take these differential measurements. However, we still believe that the WPS500X should remain a technician's pressure probe of choice.
Q: What adapters are in the PICO-PQ334 Kit?
A: The pack includes the TA393 PicoBNC+ 14-bar Pressure Transducer with a 1/4" NPT output and a TA413 Foster Series 2 to ¼"NPT Adaptor so that the transducer can connect to our existing range of pressure test adaptors and accessories.
