The PAMAS S4031 WG is a portable particle counting system for water-based hydraulic liquids (Water-Glycol), mainly used for hydraulic systems in the offshore oil and gas industry. The wear-resistant ceramic piston pump in the PAMAS S4031 WG ensures a constant flow while the volumetric cell design of its sensors guarantees the highest accuracy, resolution and best statistical information; both are important factors in its ability to be calibrated fully according to ISO 11171.
The PAMAS S4031 WG is capable of measuring up to 32 free adjustable size channels, offering laboratory accuracy and repeatability combined with real portability.
Three different channel settings for polyglycol measurements are pre-set in the system:
SAE AS 4059, channels A – F, 4 – 70 µm(c):
Calibration in six size channels: > 4, > 6, > 14, > 21, > 38, > 70 µm(c)
SAE AS 4059, channels B – F, 6 – 70 µm(c):
Calibration in five size channels: > 6, > 14, > 21, > 38, > 70 µm(c)
NAS 1638, 5 – 100µm:
Calibration in the size channels > 5, > 15, > 25, > 50, > 100 µm
With a simple-to-use touch screen user interface, operation is easy and intuitive. Functionality of key programs within the easily navigable menu system are password protected for different user levels. The S4031 WG is equipped with an integrated battery for more than three hours operation and data storage of more than 4000 measurements. It is usable for both batch sampling and online measurements. The required power supply is wide ranging; 90-230 VAC at 50-60 Hz / 12-30 VDC or using the integrated battery for up to three hours operation.
The pressurised sensor avoids the formation of gas bubbles in the sample during testing, however for very aerated fluids please also consider the PAMAS SBSS bottle sampler due to its degassing capability.
The PAMAS S4031 WG is available as the standard unit or as the S4031 WG GO (built into a rugged case for harsh environments).
