LMK 351 Screw in Transmitter
Brand: BD SensorsThe screw-in transmitter LMK 351 has been designed for measuring small system pressure and level measurement in container.
The LMK 351 is based on an own-developed capacitive ceramic sensor element.
Usage in viscous and pasty media is possible because of the flush mounted sensor.
For the usage in aggressive media a pressure port in PVDF and the diaphragm in Al₂O₃ 99.9% is available.
An intrinsically safe version complete the range of possibilities.
