USLT Internal Diaphragm Threaded Type

The USLT construction is designed for those applications where the existing threaded process connection is too small to use a flush diaphragm seal. 

The USLT consists of an upper and lower housing, the upper is the actual seal part with a diaphragm size that allows for measurement of relatively low ranges (10 mbar 2 seals attached (dP); 80 mbar single seal attached). The lower housing creates the transition from the diaphragm size to the smaller process connection. 

USLT is used in combination with (differential) pressure transmitters for applications such as level, flow and pressure measurement; also the USLT is often combined with pressure gauges.
