LF-Series 位移传感器

RENYWELL offers the LF transmitter configured with a Flexible hose constructed of 316L stainless steel (see illustration below). The flexible hose configuration can be ordered in lengths from 3048 mm (120 in.) to 22,000 mm (866 in.). The LF transmitter for flexible hose applications is typically ordered with a 1 in. adjustable MNPT fitting. This fitting allows the transmitter to be adjusted (within a few inches) if the order length is not exact.

The LF transmitter ‘Measuring range’ is equal to the ‘Order length’ minus the ‘Inactive zone’ (refer to the Transmitter Inactive Zone Reference table below). The ‘Order length’ should equal the ‘Tank height’ minus 51 mm (2.0 in.). The transmitter can be ordered with a single product float or can include the optional interface float (Refer to the Level Plus Accessories Catalog, document no. 551103 for optional float selections). If required, temperature measurement is also an option.

 
 

A stop collar is also included which is designed to keep the float out of the inactive zone. The placement of the stop collar is dependent on the float and placement of the magnet. If your application requires measuring to the bottom of your vessel, ask RENYWELL about our ‘low liftoff’ ’ float option which can measure less than 25 mm (1 in.) of liquid.
