Description
Model F3833 Bending beam
For rated loads up to 500 kg [1,102 lb]
The model F3833 bending beam is suitable for static and dynamic measuring requirements in both tension and compression force direction. It serves for determining bending forces or weights in diverse application areas.
This bending beam is used in industrial weighing and laboratory technology, and also in the process industry, and features high measurement accuracy.
The bending beam is also used for gravimetric level measurement of vessels such as silos or tanks.
Various load feet and mounting kits are available for mounting or attachment to the base.
Depending on the application, corresponding approvals are available.
The material of the measuring body is stainless steel.
An mV/V signal is available as a standard output signal, which can be amplified to an analogue signal using a cable amplifier or summed via a junction box. A junction box with up to four inputs is available for combining several bending beams.
The measured weight can be displayed using a weighing indicator.
In combination with the model NETRIS®F radio unit, the measured values of the instrument can be transmitted wirelessly. This radio unit can be used to realise solutions for web-based remote monitoring.
