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.

OSM2 Pro – explainer: contamination-free oil sampling at the transformer

Every oil analysis is only as good as its sample. A single air bubble or a residue of old oil in the line distorts the result. The OSM2 Pro Oil Sampling Box takes insulating oil samples fully automatically and free of contamination – directly at the transformer. Connect: link the oil inlet and outlet to the transformer with quick couplings. Flush: select the flushing volume on the rotary switch – at the push of a button, the box flushes the line automatically. Fill: the syringe is flushed twice and then filled without bubbles. Pressure-controlled cylinder movement prevents any pre-degassing. Secure: up to four syringes of 50 ml each travel safely to the lab inside the box. Battery-powered, just 7.5 kg – and suitable for mineral oil, esters and synthetic oils. Compliant with IEC 60475. OSM2 Pro. The clean sample – from Energy Support.

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.
