Please check out our newest submersible level transmitter with transient protection, the PX633, many ranges are in stock, available for immediate delivery, and are priced competitively.The PX633's inverted cone seal extends working life of cable and transducer in conditions where the sensor may experience severe stress from turbulent process media. The PX633 submersible level transmitter is the optimal choice to satisfy all of high demand level measuring applications. The PX437 are only available for a limited amount of time and the permanent replacement will be our PX633.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.
