Hydraulic Testers PPC

The STAUFF PPC series of Hydraulic Tester are state-of-the-art instruments designed to diagnose certain variables in today’s hydraulic and pneumatic systems like pressure, differential pressure, temperature, flow and hydraulic power.

Depending on the type chosen, the STAUFF PPCs can analyse, store and process all data in a PC or notebook. The Hydraulic Testers are specially designed for today’s increasing demands of system monitoring, trouble-shooting and determination of important values.

  • Pressure Sensors; Temperature Sensors; Rotation Speed Sensors; Flow Turbines; Flow Meter

The PPC-04 is a very easy to handle mobile measuring device controlled by only 8 buttons and allows the connection of up to two sensors. The measured data is displayed on the double spaced screen as numeric values.

The larger PPC-06 / 08 / 12 Hydraulic Testers are available as three, four or six channel models having an internal data storage capability of up to 250,000 data points. The unit displays measurements not only as numeric values but also in graphic form.

Laser Particle Monitor System LPM 1

The STAUFF Laser Particle Monitor System LPM 1 is a laser based 4-channel inline particle monitor designed for the continuous monitoring of particle contamination. The LPM 1 provides cumulative particle concentration information at >4 μm(c), >6 μm(c) and >14 μm(c) sizes applicable to the ISO 4406, ISO 11943 and ISO 11171 requirements for optical particle counters. A > 21 μm(c) channel is also provided for larger particle concentration information.

Machine operators are alerted to changes in particle contamination levels in a machine’s fluid by the indications provided from the LPM 1. The contamination level will be shown on the display or can be transmitted via the RS-232 serial port into a personal computer. With the ModBus-serial port the data can be transferred into a computer network or to an external display. The LPT particle sensor can be configured via an IR-port on a Palm or Pocket Computer. The LPM 1 system consists of a Laser Particle Transducer LPT and a Laser Interface.

STAUFF Laser Particle Counter

The STAUFF Laser Particle Counter LasPaC II-P is a laser based 8-channel particle counter designed for monitoring the degree of contamination of mineral based hydraulic fluids.

In contrast to other commercially available particle counters, the LasPaC II-P is characterised by a few particular features, just to mention only the large LCD display, a most comfortable QWERTY keyboard, the integrated printer and the powerful rechargeable battery, which enables on-the-spot measurements, even in cases where a direct connection to an external power supply is not available. Using the LasPaC II-P is fully intuitive, thus allowing easy and quick working with the unit.

An additional sensor to determine the temperature and moisture of fluids is available on request. Besides using the LasPaC II-P in a pressurized hydraulic system, it also allows the so-called «Bottle Sampling», the subsequent analysis of previosly sampled media.

The readings from the LasPaC II-P will immediately indicate the exact condition of the hydraulic system, the data will be documented, and you will be able to intervene at an early stage in order to prevent wear and damage to the components in the hydraulic system.

This does not only minimise repair costs, but also reduces overall equipment downtime and protects the environment.

Test Points


STAUFF TEST has established a reputation for a comprehensive range of test points and accessories for hydraulic and pneumatic systems for many years now.

STAUFF TEST stands for a varied spectrum of screw-in test points and test couplings for tube fittings, which are oriented to international standards and therefore guaranteed to comply with the requirements of applications all over the world.

The extensive range of accessories, including measuring hoses and pressure gauges (mechanical and digital/electronic) means that the initial test points fitted onto machines and service kits with measuring instruments can be obtained from a single source.

Pressure Switches

Stauff pressure switches are versatile, economically priced units with good hysteresis characteristics. The range covers low-cost miniature switches, vacuum switches, pressure switches, and differential pressure switches.

  • Subminiature Diaphram and Piston types MS-PS

New MS-PS adjustable pressure switches, available either in diaphragm execution up to 100 bar or piston execution up to 300 bar. Diaphragm and piston MS-PS pressure switches are particularly suitable to monitor pressure in automation, hydraulics, gas distribution, fire prevention, lifting systems, pharmaceutical industry, lubrication plants, refrigeration and so on.

  • Piston Type

This model is a piston-spring type pressure switch. With pressure at zero the micro-switch remains pressed and will only be released when the adjusted switching pressure has been reached. The piston acts against an adjustable spring with travel mechanically limited to 0.5mm, giving minimum work of good resistance to overpressure. The design of the spring .. prevents overtightening. Adjustment by turning the screw top (or knurled knob) which can be fixed with a locking screw. The complete adjusting travel is approx. 9 mm.
