Sampler for free-flowing granular bulk materials
In industries handling granular bulk materials, it is essential to obtain representative samples in both atmospheric and pressurized environments. Challenges include avoiding material separation and ensuring the integrity of the sample taken.

Take precise samples from granular bulk materials
The GC Granucheck sampler by Zeppelin Systems is designed for extracting samples from free-flowing, granular bulk materials and coarse powders. It operates effectively under normal atmospheric conditions or with overpressure up to 1 bar (g). The sampler allows switching between continuous and non-continuous operation to adjust the sample size through sampling duration. With its robust and compact design, the sampler can be directly installed as it is pre-piped and pre-wired for a terminal box. Stainless steel construction and weld-on connecting pieces in various angles and stroke lengths ensure durability and adaptability. The system’s electro-pneumatic drive and proximity sensors enable precise control of the sampling process, making it reliable and low-maintenance.
