The PH-EMS is an easy-to-install sealed bladder that is to be installed at the end of the pressure sensor vent tube. The sealed bladder protects the sensor from moisture that can affect a pressure sensor's performance and accuracy over time. For years of trouble free protection, Madison Company offers the PH-EMS environmentally-sealed bladder but also offers the PH-FIL desiccant filter, which changes color from light blue to pink if moisture passes into the vent tube over time.
The PH4201 Series hydrostatic submersible pressure level sensors are specifically designed for pressure and hydrostatic level measurements of groundwater, wastewater, process liquids or sea water. Ideal for tanks, small size bore holes, wells, dams, irrigation, sewage, rivers or oceanography, these pressure sensors accurately measure the height of the water column above by sensing the pressure of that specific liquid sensed. The titanium housing provides immunity to virtually all environments, including brackish water, sludge or other chemicals better than most stainless steel transducers. The sensor’s polyurethane vented cable is molded to the sensor housing to provide the most reliable waterproof sensor proven through many years of experience and varying liquid sensor applications. The pressure sensors come standard with polyurethane cable, but can be custom configured with FEP cable for oils or other chemical resistance. To avoid any cable elongation in Deep Well applications sensing down to 1000 feet, an integral Kevlar strand supports the sensor. A feature of the PH4201 is that its full-scale range can be designed as low 0-30” WC making it ideal for small tanks, process run off and water vessels, but can also work reliably to sense pressures to 150 psi. These sensors include a 1/2”-20 process connection under the "Drop-In" nose cone for external mounting to process fittings.
*Note: A Desiccant Filter (P/N PH-FIL) or Environmentally-Sealed Bladder (P/N PH-EMS) are recommended to insure years of accurate, trouble free service.
