1. VKK1-4 / VKK1R-4 junction box

The HBM VKK1-4/VKK1R-4 junction box can be connected in parallel to four sensors with a 6-wire connection. The shield design of the HBM product is available in accordance with EN 45 501 EMC shielding.
The traditional method of terminal box is to use a shielded grid for shielding. This method is limited in the EN 45 501 standard, especially in the case of magnetic field interference, which will lead to measurement errors.

Key characteristics

Used for parallel connection of four sensors (VKK1-4)
Integrated resistor network for four corner adjustment
HBM shielding method completes EMC protection
Protection level Protec IP65
VKK1R-4 stainless steel housing

VKK2-8, VKK2R-8 junction box

The HBM VKK2-8/VKK2R-8 junction box can be connected in parallel with 8 sensors with a 6-wire connection. The shielding design of HBM products is available in accordance with EN 45 501 EMC shielding.
The traditional method of terminal box is to use a shielded grid for shielding. This method is limited in the EN 45 501 standard, especially in the case of magnetic field interference, which will lead to measurement errors.

product description

VKK2R-8 Ex ATEX 95 junction box

The HBM VKK2R-8Ex EEx junction box is ATEX 95 compliant. It is suitable for use in potentially explosive environments such as the oil industry.
With the junction box, the weighing instrument can be connected outside the hazardous environment without the use of a safety barrier.

product description

Connect 8 analog sensors and meet EMC certification. VKK2R-8Ex EEx junction box uses EMC-compliant cable to ensure that the product fully meets EMC protection standards. There is a HBM resistance net inside the
junction box , high precision, and very reliable four corners. Adjustment function. This means reliable results in just 3 steps:

Four-corner adjustment,
Read the correct value from the chart,
Activate the balance resistor network.

The VKK2R-8Ex EEx junction box labeled II 2 G/D and II 3 G/D can be used in potentially explosive environments and has a PTB 05 ATEX 2014 certification. The junction box can be used in Zones 1, 2, 21 Protection .
