The FMS measuring amplifier. Experience makes the difference.
From the first analog measuring amplifier EMGZ 306 (which is still produced today with a few revisions along the way) to the latest generation of devices with connection to fieldbus and Ethernet networks, FMS has delivered countless numbers of measuring amplifiers all over the world.
Solutions of all kinds
Each project has its own special challenges. However, with its wide product range, FMS is always able to find a suitable solution for even the most demanding applications. Our close collaboration with our customers contribute to the development of our digital amplifiers and also allowed FMS to develop a wide range of network-enabled devices.
It is all in the mix
With the right combination of performance, economy and ease of use, FMS offers you its measuring amplifiers and optimal signal processing for web tension control.
Function description
All FMS measuring amplifiers are enabled to accept a 24 VDC supply. The amplifier feeds the force sensors with a highly stable excitation voltage of 5 VDC. The output mV signal of the force sensor is amplified and processed within the amplifier. The roller weight is compensated using the Offset (>0<) function. During calibration (CAL), the gain is defined, which then determines the correct conversion to the desired force value. The output signal of the amplifier is the output ready for use in your PLC or another high-level controller. The FMS product range consists of numerous measuring amplifiers with a wide variety of basic properties. In addition, FMS offers additional options to meet all your specific needs. These include different types of operating and configuration options, versatile mounting methods, and a large selection of Ethernet protocols, as well as additional inputs and outputs. Measuring amplifiers from FMS can be found in applications in the converting, paper, metal and textile industries as well as in the manufacture of wires and cables.
Questions and answers
What are the advantages of ethernet communication over power outputs on a measuring amplifier?
The resolution of sensitive force sensors and amplifiers can be used much better using a 16 bit word instead an analogue signal (with a measuring range of 1:50 the signal is as small as 20 mV at lowest measurable point). Wiring of machines can be reduced a lot, and especially modular machines are much easier to connect from module to module.
What’s the difference between analogue and digital measuring amplifiers?
Analogue amplifiers use many more components that are temperature dependent, the worst being the potentiometers to adjust offset and gain. Signal filtering depends on capacitors that will lose their capacity over time. In digital amplifiers all parameters are stored reproducibly in a memory facilitating a replacement without recalibration.
