MOLOSpressdec MSD-A4 for effective pressure monitoring

MOLOSpressdec MSD-A420 with robust metal housing measures the pressure in silos and containers. It records the pressure increase during pneumatic filling with maximum precision and converts the pressure into a standard industrial signal of 4-20 mA. This allows you to react at any time if necessary. The MSD-A485 is also available with a bus interface.
