Product catalog summary
Overview: The UNS2000 Level Switch Series is a versatile multi-level switch system capable of accommodating up to six switchpoints and a maximum length of 3000 mm. It is designed for detecting liquid levels using float-operated reed contacts and can be equipped with temperature sensors or contacts.
Specifications:
  • Max Operating Pressure: 40 bar, dependent on mounting element and float.
  • Temperature Range: -10°C to +105°C with PVC cable, -40°C to +150°C with silicone cable, ATEX Exi limited to -40°C to +75°C.
  • Protection Class: IP65 standard, IP67 and IP68 available on request.
  • Approvals: ATEX and IECEx Exi intrinsically safe certifications.
Design and Customization: The switch can be customized with various mounting elements, electrical connections, and materials. Options include split versions for long units or large flanges to reduce shipping and installation costs.
Technical Data:
  • Ambient Temperature Range: -20°C to +75°C for PVC and CR cables, -40°C to +75°C for SI, PUR, FEP cables.
  • Electrical Ratings: Ui = 28 V, Ii = 125 mA, Pi = 0.5 W.
  • Internal Capacitance and Inductance: Ci = 2 nF, Li = 10 μH.
Order Code and Options: The order code specifies the type, material, mounting element, electrical connection, float type, number of switchpoints, contact modes, and additional options such as high-temperature applications and damping tubes.
Materials and Mounting: Available in brass and stainless steel versions, with various mounting threads and flanges. Electrical connections include cube plugs, angle plugs, M12x1 plugs, and terminal boxes.
Float Types and Specifications: Different float types are available, each with specific density, material, form, diameter, maximum temperature, and pressure ratings.
Contact Modes: Options include SPST (NO), SPST (NC), and SPDT (WE) with specific voltage and current ratings.
Applications: Suitable for various industrial applications requiring precise liquid level detection and temperature monitoring.

UNS 2000-1

Level Switches UNS2000 The multi Level Switch Series UNS2000 can be supplied with up to 6 switchpoints (see max. switchpoints) and with a length of max 3000 mm. Besides the float operated reed contacts to detect liquid levels, the UNS 2000 can be supplied also with a temperature sensor and/ or temperature contact(s), which are to handle as switchpoint(s) -please note max. switchpoints! A wide selection of mounting elements, electrical connections, various materials and options allow you to "design" your own switch, within the given dimension limits, for your particular application. Very long units or large flanges can cause high shipping and installation costs and "split" versions might be the answer. Consult us for the best combination. The min. dimensions are based upon the medium water. Depending on the density of other fluids this dimension can vary several millimetres. The contact modes (NO or NC) are defined on the basis of an empty tank and for installation through the top or through the bottom (when specified as "-U"). When not specified otherwise we will set the switch position for density 1 (water) and the switch action to be on moving upward. Temperature sensor (PT100) and/ or the temperature switch, a Bi-metall hermetically sealed element, are installed only in the bottom of the stem. That means: Dimensions B + 10 mm with temperature sensor PT100) = BPT Dimensions B + 40 mm temperature switch (TP) = BTP Contact Wiring parallel circuit single circuit Group 4 single circuit (SPDT) Terminal Subject to technical changes.
