Level transmitter endures aggressive chemicals
The LMK331 Screw-In Level Pressure Sensor has an aggressive media resistant construction which makes it suitable for measuring fluid level of a wide range of corrosive chemicals.
The flush pressure sensing element of the LMK331 flush diaphragm level sensor is a ceramic based thick film strain gauge diaphragm which has highly stable measuring properties due to ceramic's excellent elastic properties. Ceramic is also very hard wearing and resistant to abrasion and corrosion from a wide range of hazardous liquids.
The pressure port of the LMK-331 ceramic level transmitter can be made from either PVDF, PVC or stainless steel depending on the required chemical compatibility.
The ceramic diaphragm of the LMK-331 chemical resistant level transducer is sealed onto the pressure port with an o ring which can be made of Fluorocarbon Elastomer (FKW) for mineral acids, salt solutions, chlorinated hydrocarbons or petroleum oils; Nitrile Rubber (NBR) for paraffin base materials, fatty acids, oils, alcohols or glycerines or Ethylene Propylene Diene Monomer (EPDM) for many types of alkalines and acids.
The LMK331 hydrostatic pressure transmitter is typically mounted to an external G1/2 or G3/4 tapping point of an Intermediate bulk container (IBC) by simply screwing in by hand with the aid of the knurled body ring.
The LMK331 chemical level sensor is available in ranges from of 1.6 to 600 metres of water gauge for measuring the contents of various sized chemical tanks.
Either an output signal of 0-10Vdc amplified voltage or 4-20mA current loop can be selected with the option for ATEX approved electronics when intrinsic safety is required for installations in hazardous areas.
