Product catalog summary
Features:
  • Load capacity ranges from 0.5 t to 5 t (2 kN to 50 kN).
  • Approved for use in calibrated weighing systems.
  • High accuracy with classes C1, C3, or 0.1 and 0.05.
  • Hermetically-sealed housing with IP67 protection.
  • Constructed from stainless steel for durability.
  • Easy assembly with available appliances.
  • EU approval (not available in the U.S.).
Description:

The ZS load cells are crafted from special stainless steel, making them suitable for challenging environmental conditions. The sensor element is a transverse body protected by a welded metal diaphragm, ensuring consistent measurement characteristics. Compensation and adjustment elements are housed in a sealed chamber. The load cell can handle both traction and compression forces, and an assembly kit is available for easy installation. Standard models come with a 3-meter connection cable and can be calibrated in Newtons (N) for high precision up to 0.05% accuracy.

Specifications:
  • Test report No. D09-96 for ZS 0.5 t, 1 t, and 2 t nominal load.
  • Force transducers/load cells with pin connections for supply and measuring voltage.
  • Optional internal amplifier for output signals of 0(4) - 20 mA or 0 - 10 V.
Mechanical Characteristics:
  • Nominal force ranges from 2 kN to 50 kN.
  • Maximum permissible force/load is 150% of nominal force.
  • Ultimate overload capacity is greater than 300% of nominal force.
  • Maximum transverse force/load is 10% of nominal force.
Electrical Characteristics:
  • Nominal sensitivity is 2.000 mV/V with a tolerance of ±0.002.
  • Zero tolerance band is ≤1%.
  • Maximum excitation voltage is 12 V.
  • Input resistance is 380 Ω ±30, and output resistance is 352 Ω ±1.5.
Environmental Characteristics:

ZS Series-1

Q MAGTRO L Note: Not available in U.S. ZS Series Load Cell FEATURES • 0.5 t to 5 t (2 kN to 50 kN) • Approved for use in calibrated weighing systems • High accuracy (C1, C3 or 0.1 and 0.05) • Hermetically-sealed housing (IP 67) • Made of stainless steel • Appliances for easy assembly • EU approval * DESCRIPTION The ZS load cells are made entirely of a special stainless steel and are, therefore, also suitable as weighing plants under difficult environmental conditions. The sensor element itself is fabricated as a transverse body. A metal diaphragm, which is welded on to the deformation zone protects the sensitive strain gauges from environmental influences. As a result constant measuring characteristics are ensured. Compensation and adjustment elements, which are required for the exact setting of the guaranteed technical parameters, are positioned in a special chamber, which is also sealed. The load cell can be subjected to traction or compression force. An assembly kit, which can be ordered separately, facilitates the unproblematic and safe installation of the load cell in the weighing unit. As a standard, the load cells are supplied with a 3 m long connection cable. Of course, these load cells, calibrated in Newton (N), can also be supplied as high-precision transducers up to the accuracy class 0.05%.
