Engine and hydraulics diagnostic kit

With high accuracy and a wide measuring range, the WPS600C Hydraulic Pressure Transducer connects to your PicoScope for convenient analysis and diagnosis of pressurized systems.

The Pico Engine and Hydraulics kit combines our Diesel diagnostics kit with two WPS600C Hydraulic pressure transducers, enabling you to accurately and quickly diagnose faults on many different types of mobile machinery. PicoScope has already been chosen by dozens of vehicle and equipment manufacturers because of its unique combination of value, reliability, performance and guidance. 

By combining the high-precision hydraulic transducers with a PicoScope kit, you can now look at hydraulic pressures in the same time frame as the engine control signals giving complete visibility of how the system is operating.  You can now see the exact moment valves start to move in the hydraulic system and compare this directly to the relevant electronic controls. You can also investigate stalling and 'no start' conditions due to the comprehensive coverage of engine and electrical systems.

With PicoScope you have direct access to over 150 built-in guided tests covering engine and electrical sensors, actuators and systems. These include both voltage and current measurements and cover camshaft, crankshaft, oxygen sensors, injectors and many more. These tests give you a head start in diagnosing and fixing engine faults right first time; when combined with the hydraulic system they allow diagnosis of complex interactions of the hydraulic and engine systems.

WPS600C pressure transducer

With high accuracy and a wide measuring range, the WPS600C Hydraulic Pressure Transducer connects to your PicoScope for convenient analysis and diagnosis of pressurized systems.

  • Accurately measure up to 600 bar (8700 psi)
  • Ultra-fast 100 microsecond response time (0% to 90% of full scale)
  • Internal rechargeable LiPo battery
  • Industry-standard M16 x 2 test point connector
  • Auto zeroing
  • High noise immunity
  • Temperature compensated

Not for continuous operation

Due to the wide range of hydraulic fittings in use we do not supply any specific adaptors or hoses for use with this product. Those provided with the low pressure WPS500X are not suitable for use with the higher pressure hydraulic systems.

We recommend contacting your regular hydraulic hose supplier for any additional fittings or custom hose assemblies you may require to suit your specific system.

Pressure ranges

Two pressure ranges for increased versatility
The two pressure ranges of the WPS600C allow accurate measurement and diagnosis of permanent and non-permanent automotive and industrial hydraulic systems.

Range 1
The first range, 0 to 600 bar (approximately 8700 psi) gives you high resolution and accuracy for high-pressure tests in hydraulic systems.

Range 2
The second range measures from 0 to 60 bar (approximately 870 psi). This range is ideal for low-pressure hydraulic systems and oil pumps.

Range Pressure range Accuracy Response time Output scaling

Flow meters

To go with the Hydraulics diagnostics kit Pico can supply a range of flow meters designed to work directly with your PicoScope. The Pico flow meter range has been developed in conjunction with industry leading flow meter supplier Webtec and are based on their very popular range of turbine flow meters.

At Pico we can offer you 3 different sizes of Flow meter -  25lpm, 300lpm and 600lpm.  All flow meters come with a flow output for direct connection to the PicoScope and an embedded thermistor for measuring oil temperature.  They also have an M16x2 Minimess pressure test port for connecting your WPS600C to.  The 2 larger sizes also have a built in loading valve to eneable the opertor to load the hydraulics system under test allowing you to see the system performance under full load.

For ease of connection the flow meters are supplied with either SAE or BSP inlet and outlet ports depending on your requirements.

More information on the Diesel diagnostic kit


As well as the above 2 kits, the Engine and Hydraulics diagnostics kit also includes a box of 18" gear ties and a pair of 5M long TA130 BNC to BNC cables in addition to those normally shipped with the Dual Hydraulics add on kit.

Nothing compares to the WPS600C
It is not unusual to require a different pressure transducer for each diagnostic test you want to run. The WPS600C eliminates this need by giving you one ultra-high resolution transducer that can be used for a multitude of hydraulic diagnostics applications. With two pressure ranges and a rechargeable Li-Po battery, all enclosed in a durable housing the WPS600C is the cost-effective answer to pressure analysis.

When price, performance and versatility matter, there is nothing that compares to the WPS600C Pressure Transducer.

Typical Uses

The Engine and hydraulics kit is designed for you to be able to diagnose problems on your equipment, relating to either engine or hydraulics. Allowing pressures up to 600 bar to be monitored against time enables the technician to connect the WPS600C to the relevant hydraulic test port, then view activity and transitions in hydraulic pressure that were never previously visible with conventional gauges.

  • Hydraulic pump performance
  • Hydraulic valve switching activity
  • Hydraulic pressure control valve performance
  • Hydraulic pressure decay
  • Residual hydraulic pressure

Robert Burgy
WPS600C Hydraulic pressure transducer

Being an automotive instructor, i get the benefit of using tools that would not usually be in an everyday shop. This hydraulic transducer is one of them. the quality of this one is the same as all of the other Pico test accessories. If you have used the WPS500. Then this will be the same. Theres just not enough space to talk about all of the time these save you.

WPS600C Hydraulic pressure transducer

The local Community College that I instruct for Part Time got a 4423 Kit from Case New Holland on order and in the kit it comes with two of these Transducers.  Another instructor and me tried it out on a Bulldozer looking at the pressures of the blade going left to right with current clamps on the solenoids.  Wow!  It will show the pressures exactly as the pressure builds and dumps when the solenoids turn on.  This Transducer is on my wish list.  This unit is going to work great for testing pumps and valves.  Can’t wait to get one! Thank you Pico!
