Although you can buy a WPS500X and accessories separately you can save money by purchasing the WPS500X Pressure Transducer Kit. The kit includes the WPS500X Automotive Pressure Transducer together with a large selection of hoses and adapters – everything you’re likely to need and at a reduced cost compared to buying everything separately.
The three pressure ranges of the WPS500X allow for accurate measurement and analysis of many automotive pressures including cylinder compression, fuel pressure, intake manifold vacuum and even pulses from the exhaust.
The first range gives you high resolution and accuracy for high-pressure tests such as cranking and running cylinder compression or fuel pressure testing. Not only is this test a great way for you to find compression issues, but it is also an excellent way for you to identify cam timing issues such as jumped timing belts and stretched timing chains – this is especially useful on multi-cam engines that may not have a cam sensor on each camshaft.
The second range measures from –15 to 50 psi(approximately –1 to 3.45 bar). This range is ideal for vacuum tests and fuel system tests. When testing these systems you will find the zoom function is especially useful as it makes it easy to analyze the valves operating with the vacuum waveform, or the injectors through the fuel waveform.
With the third range you can measure –5 to 5 psi (approximately –0.34 to 0.34 bar). This setting is sensitive enough to allow you to analyze small pressures or pulses such as pulses from the exhaust.
|Range||Pressure range||Accuracy||Response time||Output scaling|
|1||–15 to 500 psi
–1 to 34.47 bar
|1% of scale||100 µs||10 mV/1 psi
(500 psi = 5 V)
|2||–15 to 50 psi
–1 to 3.45 bar
|1% of scale||100 µs||100 mV/1 psi
(50 psi = 5 V)
|3||–5 to 5 psi
–0.34 to 0.34 bar
|5% of scale||filtered||1 V/1 psi
(5 psi = 5 V)
The zoom function operates by removing all of the voltage from the signal below 100 Hz and then multiplying the remaining signal up to 100 times. For example: Let’s say your transducer is connected to the intake manifold vacuum on a running engine at idle with the transducer set to mode 2 (-15 to 50 psi) and the waveform on your PicoScope is at -9 psi. The fluctuation in the signal caused by the valves opening and closing versus atmospheric pressure forcing air into the manifold will be visible, but will only make up a small portion of the overall signal. Selecting the zoom function will bring the waveform up to the zero line and the fluctuations will be magnified making analysis of this component of the signal much clearer.
It is not unusual to require a different pressure transducer for each diagnostic test you want to run. The WPS500X eliminates this need by giving you one ultra–high resolution transducer that can be used for a multitude of automotive diagnostic applications. With three pressure ranges, a zoom function, pressure relief valve and a rechargeable Li–Po battery all enclosed in a durable housing the WPS500X is the cost–effective answer to pressure analysis.
When price, performance and versatility matter, there is nothing that compares to the WPS500X Automotive Pressure Transducer.
The pressure transducer has become the essential diagnostic tool to assist with a multitude of pressure related tasks from -15 psi up to 500 psi, so replacing the majority of analogue gauges used today. With the ability to measure pressure against time we can now witness rapid events taking place that were never previously visible. Incorporated into the pressure transducer kit you will find multiple adapters and hoses to assist with a selection of the tests listed below taking diagnostics to a whole new level.
