What is the Simco FMX 004 electrostatic field meter used for?
The Simco FMX 004 is a handheld electrostatic field meter from Simco-ION for locating and measuring static electricity on materials, machinery and production lines. This type of instrument is also described as an electric field meter.
The meter is used for troubleshooting, process control and evaluating ionizing equipment. It can help identify where a static charge occurs, how severe it is and whether an installed ionizing bar is reducing the charge as expected.
FMX-004 measures both positive and negative static voltage up to ±30 kV. The measurement and charge polarity are shown directly on the digital display.
Correct measuring distance using LED points
To obtain a reliable measurement, FMX-004 must be held at the correct distance from the material. The instrument has two integrated LED points that indicate the correct measuring distance of 25 mm.
When the two light points meet on the surface of the material, the instrument is being held at the correct distance. This function makes FMX-004 easy to use and helps ensure that measurements can be compared accurately.
The instrument must be grounded correctly using the supplied grounding lead. The measuring distance, grounding procedure and instructions in the manual must always be followed to obtain a representative result.
Troubleshooting and verification of ionization
FMX-004 is Northern Grafics’ best-selling static measuring product. It is particularly suitable for companies that want to investigate static electricity problems without installing a permanent measuring system.
By measuring before and after an ionizing bar, the company can check whether the static charge is being reduced. There is no single universally acceptable kV value, as the result must be assessed according to the material and the specific production process.
If the charge must be monitored continuously during production, a permanently installed Sensor IQ Easy is recommended. If the purpose is only to check whether high voltage is present at the emitter pins, TensION can be used.
