The screw-in transmitter LMK 351 has been designed especially for level and process measurement. The pressure sensors are flush mounted allowing the use also in viscous or contaminated media. By using a capacitive ceramic sensor an excellent measuring performance is being achieved. Because of its material the capacitive ceramic sensor features high compatibility against aggressive media. Sealing of the sensor against the pressure port is made with a FKM seal. Other elastomers are available on request. The pressure port can be made of stainless steel 1.4571 (316Ti) or – for very aggressive media – of PVDF or PVC. Additional it is possible to suit the screw in - transmitter LMK 351 in explosive area (zone 0). Preferred areas of use are - level measurement, chemical industry, medical technology, pharmaceutical technology.
