1 General Description

Thank you for choosing our NTEP/NTNN series floor scale. The scale consist of new
design ultra-low profile steel platform, four high precision shearing beam load cells.
NTEP/NTNN floor scales have the features of high accuracy, quick weighing and re­liable weighing performance. The ultra-low platform means less effort required to
manually place the load on the scale. It is suitable to weigh drums, totes, small mix­ing vats, etc.
The NTEP/NTNN series are designed to provide excellent performance required for
weighing applications in postal distribution centre, distribution centre of commerce,
storage and consignment enterprises, and workshop production line, semi finished or
finished product storehouse of pharmaceutical and food enterprises

2.2 Platform Assembly

The scales have a channel reinforced platform with two angle steel welding on two
sides of platform. The junction box is mounted on the angle steel. The covers on the
angle steel can be removed to gain access to the junction box. Threaded holes are
provided on two sides of platform. When installing or removing a platform, screw lift­ing eyebolts into these holes and lift the platform by the eyebolts.

2.3 Working Principle

The elastic body of a load cell deforms under the weight onto the platform. The
Wheatstone bridge bonded to the elastic body loses its resistance balance and out­puts an analog electric signal proportional to the weight. See Figure 2-2 for the Wiring
Scheme of Floor Scale with four load cells equipped.
