A proven and preferred technology to measure the level, interface, or density of liquids in industrial processes. The level transmitters are FM/ATEX rated explosion proof and intrinsically safe, approved for SIL2 applications with a proof test interval of up to 5 years. The 167LP Pneumatic transmitter is used for measuring the level, interface, or density of liquids. It converts the lifting force of the displacer body to a pneumatic output and is ideal for extreme process level measurements.
