Features ㆍVery low cost compared to other type level equipment
ㆍRemote and local display ㆍApplicable to various liquid when the probe material is changed
ㆍItems 1~3 are same with the left
ㆍRemote display and control is possible
ㆍAvailable explosion proof

Output ㆍ 4∼20mA DC Power specifications 24 VDC

Application ㆍMunicipal water, clean water industrial water, waste water, drinking water ㆍLiquid tank of ship ㆍLPG, chemical, oil, acid, solvent ㆍetc.

Displacement Type Level Transmitter (SDT-420)

Operating Principle The variable buoyancy force exerted on a stationary displacer immersed in a liquid is transferred to a strain gauge pressure transducer through a torque tube. The pressure transducer thus turns according to the changing liquid levels into proportional electric current. The operating buoyancy of the displacer varies with liquids since buoyancy is a function of the liquid density, and the operating buoyancy is maintained by adjusting the balance spring.

Process temperature ㆍ Max. 450°C

Process pressure ㆍMax. 100㎏/㎠

Features ㆍMaximum application pressure 100㎏/㎠
ㆍMaximum applicable temperature 450°C
ㆍAutomatically sets zero and span
ㆍThe span can be set at any actual liquid level
ㆍAccurate to ± 0.2% F.S
ㆍContinuous self-diagnosis is available
ㆍThe transmitter can be calibrated without removing the cover
ㆍCorrosion resistant material is available
ㆍLevel sensing point can be easily changed
ㆍHART communication
ㆍSMART type
ㆍAvailable explosion proof

Output ㆍ 4∼20mA DC

Power specifications ㆍ 15∼30 VDC

Application ㆍHigh pressure and temperature boiler tanks of power plant ㆍ Waste water or clean water tank ㆍVarious chemical tank ㆍ Fuel & oil tank ㆍ Beverage tank ㆍetc.
