Ceramic is also very hard wearing and resistant to abrasion and corrosion from a wide range of hazardous liquids.
The other parts of the sensor exposed to the tank contents can be selected depending on chemical compatibility and either PVDF, PVC or stainless steel can be specified for the pressure port material.
There are also a selection of O ring materials used in the construction of the sensor and the pressure fitting for this chemical resistant level transducer which are Fluorocarbon elastomer (FKW) for mineral acids, salt solutions, chlorinated hydrocarbons and petroleum oils, nitrile rubber (NBR) for paraffin base materials, fatty acids, oils, alcohols or glycerines and ethylene propylene diene monomer (EPDM) for many types of alkaline 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.
No matter what size of tank the LMK331 chemical level sensor has the appropriate range to measure the contents with precision.
The output signal can be 0-10Vdc amplified voltage or 4-20mA 2 wire current loop with the option for ATEX approval if intrinsic safety is required for use in a hazardous area.
If you are searching for a level gauge to fit to the external pipe work of a chemical storage tank, the LMK331 chemical level sensor warrants a closer look.
