OIL SAMPLING BOX

OSM2 Pro

Sampling box for fully automatic, contamination-free extraction of insulating-oil samples directly at the transformer.

The OSM2 Pro Oil Sampling Box enables contamination-free extraction of insulating-oil samples directly at the transformer – the prerequisite for reliable and comparable analysis results. Automatic flushing and filling sequences deliver reproducible samples at the push of a button, on open as well as hermetically sealed transformers.

Features

All benefits at a glance

Contamination-free

Contamination-free extraction directly at the transformer – for comparable, reliable analysis results.

One-button operation

Flushing and filling start at the push of a button – simple, fast and reproducible.

Automatic flushing

Selectable flushing sequences (4 / 3 / 2 / 1.1 / 0.55 l) via rotary switch – the line is flushed reliably.

Oil temperature sensor

Integrated sensor captures the oil temperature; the pressure-controlled cylinder movement prevents pre-degassing.

For all oil types

Suitable for mineral oil, natural esters and synthetic oils – on open and hermetically sealed transformers.

Battery operation

4 Ah NiMH battery (12 V DC) – not classed as dangerous goods under IATA and therefore easy to transport.

Process

How the sampling works

From coupling to a fully filled syringe – the OSM2 Pro performs flushing and filling automatically and without contamination.

01

Connect

Connect oil inlet and outlet to the transformer via 6/8/10 mm quick couplings.

02

Flush

Start the automatic flushing sequence – the desired flush volume is selected via rotary switch.

03

Fill

Automatic filling sequence incl. flushing the syringe twice (approx. 350 ml oil consumption per sequence).

04

Secure the sample

Fix up to 4 × 50 ml syringes in the holder and transfer them to the lab without contamination.
