DLS 30

Product Description

DLS 30 Displacer Type Level Switch is a robust and reliable solution for point-level detection in liquid applications, operating on the Archimedes buoyancy principle. It uses single or split displacers suspended by a wire rope, enabling narrow or wide differential switching based on application requirements. The switch supports site-adjustable up to four switching points with micro switch or hermetically sealed reed switch outputs. Designed for harsh environments, it features a shockproof construction, IP-65 enclosure, and is radiation- and seismically qualified. Available in SS 304 / SS 316 / SS 316L, PP, or PVDF materials, it supports measuring ranges from 1000 mm up to 10,000 mm. With high repeatability, fast response time, and multiple process connection options, the DLS 30 is ideal for demanding industrial-level control applications.
