The WPS500X is an impressive pressure transducer.\u00a0 It covers a wide pressure range that would normally require multiple transducers.\u00a0 It produces a signal that will result clear, accurate, and highly resolute waveforms, allowing for detailed analysis of your readings.<\/p>\n
While you will certainly find other pressure transducers at lower prices, you will quickly be disappointed when you start comparing their performance to that of the WPS500X.<\/p>\n

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 \u2014 this is especially useful on multi-cam engines that may not have a cam sensor on each camshaft.<\/p>\n Range 2<\/h4>\nThe second range measures from \u201315 to 50 psi (approximately \u20131 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.<\/p>\n Range 3<\/h4>\nWith the third range you can measure \u20135 to 5 psi\u00a0(approximately \u20130.34 to 0.34 bar). This setting is sensitive enough to allow you to analyze small pressures or pulses such as pulses from the exhaust.<\/p>\n When would I use the WPS500X?<\/h2>\nOften, problems reported by customers can have many potential causes, and simply reading fault codes leaves you no closer to a solution. In addition to the comprehensive electrical testing provided by PicoScope, the addition of a WPS500X provides you with that same detailed insight into the engine system for accurate diagnosis of common problems such as:<\/p>\n
