LTD Differential Transmitter

APPLICATIONS:

To measure pressure drops across filters
Pumps and compressors, flow measurements of gases and liquids, liquid level measurement of pressurized vessels

DESCRIPTION & FEATURES:

Designed to measure the differential pressures of liquids and gases between two ports
Compact, efficient design available in Low or High psi ranges that facilitates installation in tight spaces
Low Range housing is constructed of stainless steel and aluminum
High Range housing is made from a 316-grade stainless steel ideally suited for an industrial environment
Fast response sensor and signal conditioned electronic circuitry provide quick and accurate readings
Unique isolation system responds to pressure changes approximately 20 times faster than conventional transmitters with ranges below 100 psi (Low Range model)
CE approval is standard on all models
NEMA 4 approval is standard on the Low Range model
RoHS compliant
5 year warranty
