ESL040-C Level Transmitter for Sea Water
ESL040-C is a level transmitter for sea water and seawater-related & aggressive gases measurements.
ESL040-C is kind of submersible level probe, by adopting high purity ceramic diaphragm and titanium alloy material, ESL040-C can handle the seawater-related & aggressive gases measurements (with high accuracy @ 0.1% class).
It can stand with long distance transmission and produce 4-20mA +HART protocol communication, the product line is highly reliable and stable, and enables digital compensation within full temperature range.
What’s more, the wide diameter (Φ 32.4 mm) and the use of the capacitive technology make the ESL040-C suitable for measuring very low pressures, as low as 60 mbar.
The ESL040-C adopts titanium alloy construction to the system and housing, the latest digital compensation technology to ensure no losing of accuracy within the full temperature range, and enables zero/span trim through computer interface and external program-controlled zero/span adjustments.
