OMEGA’s PX437 PX438 and PX439 Series submersible water level transmitters are designed to meet the rigorous environments of applications including well monitoring pump tests lift stations chemical tank level ground water and surface water measurement and process control and many others. They provide repeatable precision depth measurements under the most adverse conditions.These transducers utilize a silicon pressure cell fitted into a stainless steel housing with an integral welded 316 stainless steel barrier diaphragm. The supplied calibration sheet specifies input and output data which reflects the unit’s static accuracy and thermal characteristics. Each transducer is shipped with a moisture trap that prevents moisture from entering the vent tube. Replacement moisture traps are available as accessory items.
