SMALL-P/IL/12/15M has passed multiple international explosion-proof certifications, including BVS 06 ATEX E005 X、IECEx BVS 09.0056X、IECEx TSA 13.0023X、MSHA 18-ISA 150004-0、TC RU C-DE.AA87.B.00727/21, Covering the European, North American, and Russian markets, with * applicable capabilities.
The equipment adopts an inherently safe Ex ia design, and the electric sparks and thermal effects generated in the event of a fault will not ignite explosive gas environments. This design does not require an explosion-proof shell, which can reduce the size and weight of the equipment, making it easy to install and maintain on site.
The equipment casing can be made of stainless steel, steel, or brass materials, and the sealing components come standard with NBR nitrile rubber or FKM fluororubber, suitable for different chemical working environments. The medium contact parts have undergone special treatment and can be adapted for use with filtered water, emulsions with a maximum concentration of 5%, oils, and similar water media.
The installation length range of the product is 50-200mm, compatible with G1 'threaded connections, and can be quickly integrated into existing pipeline systems. Equipped with a luminous display screen, it supports unit displays such as l/min, m ³/h, gpm, etc. Other units can be customized according to their needs, and data can be clearly read in dark environments.

SMALL-P/IL/12/15M is mainly used for pressure monitoring of hydraulic supports in coal mines, pressure control at pump station outlets, emulsion proportioning systems, and pressure measurement in chemical processes. The equipment adopts a 12V DC low voltage power supply and a 3-wire design, which can be easily integrated with safety barriers, PLCs, and remote monitoring systems.
Gr ü newald can provide complete measurement solutions, including SMALL-P-RG relative pressure/gauge pressure versions, SMALL-Ex series flow measurement instruments, MAGIN Ex electromagnetic flow meters, DA/DAK flow switches, and other products in the same series, which can form a complete product system for fluid measurement in hazardous areas.
