The Banner TDP 0,2 LT -4 is a robust and reliable differential pressure switch designed for monitoring contamination levels in hydraulic filters. This device accurately measures the pressure difference before and after a filter element, triggering a signal when the preset pressure drop of 0.2 bar is reached. This indicates that the filter is clogged and requires maintenance. Its durable construction ensures long-lasting performance in demanding industrial environments, helping to protect hydraulic systems from damage caused by contaminated fluid and ensuring optimal operational efficiency.
