Essay head for Field strength measuring at the current thread for EFM 231, 232 and 251
The thread measurement chamber FMK 1 is a cap electrode for our electro field meters EFM 231-251. It is used for the measurement of statics at running fibers.
The thread measurement chamber is built of a gold plated Faraday cage which is mounted on the electro field meter. This prevents failures caused by external static fields. Through a slot in the chamber the fiber is directed in defined distance to the modulator system.
