ELF series Electric Displacer Level (Interface) Transmitters
Summary
ELT electric displacer transmitter is improved on the basis of
model UTD. Still adopts the lever principle and stress
measuring method in the transmitter part, measure the
buoyancy force applied to the displacer in the liquid, acquire
the measured signal identical with location of substance change
through high precision double orifice suspension arm sensor,
and the measured signal is transferred into 4-20mA standard
signal output through a specific circuit.
The gaugehead is designed with popular style. Its sculpt is
beautiful and each operating compartment separated. And the
new model is equipped with static pressure adjustment device
which greatly improved the precision and stability. The above
mentioned two technologies have acquired the national patent.
The patent number for outward appearance design: 99 3 21507.6
The patent number for static pressure adjustment device: 99 2 23728.9
