The ELHS load cell is a compact package able to fit into many applications where others cannot. The low noise Wheatstone bridge consists of piezo-resistive strain gages which provide 200 mV of typical full scale output. When compact design, extreme stiffness and superior resolution are required, the ELHS load cell is the sensor for your application. The ELHS is provided with either SAE or metric threads for tension and compression applications.

Care should be exercised to isolate your ELHS from off-axis loads. The ELHS is a Poisson column design providing low full scale input deflection and superior resolution. Designed specifically to provide high resolution and low deflection. The ELHS can be configured with a variety of options to fine tune the instrument to your application: select from several standard compensated temperature ranges, input voltages, lead lengths or specify entirely unique combinations of these options.

Alternate calibration: units with studs are calibrated
in tension by default. Option AC provides compression
calibration in addition to tension calibration.

Note:
L = lbf; N = Newton.
Metric threaded units must have Newtons range specified. SAE threaded units must have lbf range specified. Metric threaded units must have cable lengths specified in meters. SAE threaded units must have cable lengths specified in inches.

Sicherheitshinweis

Bei Einsatz als Zugkraftaufnehmer unbedingt zusätzliche Sicherheitsmaßnahmen wie Fanglaschen, Fangketten usw., einbauen, damit bei einem nie völlig auszuschließenden Bruch des Gebers die Last abgefangen wird.
