ZC Series – Load Cells
Product Description
Note: Not available in the US.
Magtrol’s ZM Series Force Transducers are designed to measure static and dynamic pressure forces. They are characterized by their small dimensions.
Manufactured in stainless steel or high-resistance aluminum, these transducers can be used in a wide variety of applications. In particular, the stainless steel versions with a high degree of protection can be used everywhere without restriction, even in harsh environments.
The sensor element consists of a diaphragm body equipped with metal foil strain gauges, which forms a hermetically sealed chamber filled with dry nitrogen. In standard mounting, the transducers are fixed with screws on a flat surface. The force is introduced vertically (without transverse force) via the universal ball joint, either directly or via a metal adapter interface.
All Magtrol ZM Series transducers are supplied with a 1.5 m long connection cable with loose ends.
Optionally, they can be supplied with a built-in amplifier (ZM‑E). Then, an Output Signals of 0 … 10 V DC or 4 … 20 mA can be selected.
