Ideal for weight, torque, strain, pressure and stress measurements.
The INT4 series of digital panel weighing meter displays and controllers are probably the easiest to calibrate and configure - see video below.
They make commissioning fast, simple and precise, saving you time and money.
They accept most common load cell, torque, strain gauge and bridge sensors.

Thank you very much for this – this has saved me hours of work.

INT4-L load cell / weighing digital panel meter display - easy to use!
The INT4-L is our most popular 1/8 DIN weighing panel meter display which accepts standard load cells with 4 or 6 wire connection and 10V excitation up to 120mA.
This digital panel meter is easy to use and has high precision and stability. You can set the weight display to have 2, 3, 4, 5 or 6 digits, depending on the type of measurement you want to make. You can also set the decimal point position.
This load cell panel meter can be fitted with isolated output signal modules to add filling control and data sharing functions.
Tamper Proof ...
This digital panel wright meter is also available with a plain front panel. All settings can be locked to prevent changes after commissioning.
The small window in the bottom right can have text to identify the units of weight, torque or force such as kg, te, kN, lbs, Nm etc.
The display colour is available in red or green.

Shown here mounted in a wall mounting enclosure, with SPC4 IP67 splashproof front cover. The meter also has the MEM multi-program memory option, selected by a switch on the left of the display, to call up one of 2 programmed load ranges.
Here a Fusion large digital display is summating the loads measured by 6 INT4-L load cell displays. Summation is digital, with data collected over a 3 wire RS485 data link.
