Tape position sensor

mechanicalinductiveoptical

Optical, inductive, radar-based - EMG sensor technology with sensitivity Determining the strip position is the most important goal for all strip guiding solutions. At EMG, this goal is achieved via optical, inductive or radar-based sensors - always suitable for the respective installation situation and the individual requirements of your system. Wide range of applications from 0.05 mm to 16 mm tape thickness (others on request) Ionising furnace atmosphere Disturbances of the static field, e.g. during inspections by the plant personnel Water and metal vapours from the treatment processes Scale and metal-containing dust from mechanical processing Precise and reliable measurement accuracy, as insensitive to height variations of the tape Distance between sensor and light source up to 4 m (sensor gap) High reliability and ease of use Short commissioning time due to fast, simple installation (minimal installation space) Active dirt compensation through reference measuring principle Immunity to extraneous light through the use of HF alternating light Use even in harsh environments (e.g. pickling, cold rolling mill) No sensor parts in the oven Measurement from outside through the kiln wall, consisting of kiln wall insulation, closed gas-tight flange and sensor No direct contact of the antenna housing with the oven interior No deformation of the antennas possible No damage to the sensor by the strip possible No soiling of the oven interior or antenna housing No cleaning of the antennas required No need for cooling systems for sensors inside the oven Exchange of antennas or sensor electronics possible without line stop
