This dramatically reduces labor cost by eliminating plumbing/piping to a traditional trandsucer. Startup time is reduced since purging air out of the lines is not necessary. Traditional plumbed bypass assemblies are no longer required. Choose between the PW10 and PW20 model based on your anticipated PSID range.APPLICATIONS ▪Ideal for monitoring pumps and load differential pressures in HVAC systems and processes where local indication is needed. ▪Process control systems ▪Flow measurement of various gases or liquids ▪Liquid level measurement of pressurized vesselsVersatile Universal Transmitter ▪Three selectable PSID ranges per sensing element ▪Low and standard PSID range transmitter models ▪500 PSIG is ideal for high rise applications ▪User friendly LCD displays in PSID or kPaJumper selectable features for easy installation ▪Absolute mode outputs absolute value of difference ▪Port swap corrects plumbing errors ▪Fast/slow to select desired response time ▪Uni/bi directional ▪Display units in PSI/kPa ▪Test mode—forces full-scale output ▪Over range icon flashes if differential pressure is over-range, alerting technician to move range switch to next higher dp setting and rescale panel ▪Switch selectable outputs: 2-wire 4-20mA, 3-wire 0-5V or 0-10VHigh Reliability ▪Standard built-in snubbers protect sensing elements from water hammer damage ▪MEMS sensor technologySnap on deutsch sensor connection ▪Allows for mounting sensor and quick connection of wire later ▪Eliminates wire twisting when tightening sensors in pipe fittingPRESSURE PW Cable Wet-Wet SeriesSave time and money--pull wires, not pipe!Pre-wired leads for fast snap connection to sensorsDon’t waste time and money on plumbing like this ever again!Revolutionary design eliminates costly field plumbing. Simply run wires to sensors instead of costly plumbing! Also eliminates the need for costly bypass assemblies.Cables are prefabricated and snap onto sensors with industrial deutsch connectors. This eliminates wire twisting when tightening sensors.

Let us help step by step!What do I need?PW Cable Wet-Wet SeriesOptional service valve (PWBV) for live sensor swap. Order 1 PWBV service valve for each PWS element.On/Off Service ValveOrder (2) PWS sensing elements for every (1) PW transmitter. Each PWS element connects to the PW transmitter cables via snap-on deutsch connectors.PWS Sensing ElementsPW TransmitterThe configuration of the unit including powering the device, output, jumpers and PSID range selection is done inside of the PW transmitter.Cable length and type must be specificed upon ordering. ORDERING SENSING ELEMENTSStep 1Element connection type This guide is for units that include prefabricated cables with deutsch connectors cut to a custom length at the factory. (If running your own 4-conductor shielded cable through conduit is desired, see page 37 of the catalog) element numberREMOTE SENSORS: PWSElement Number100 = 100 PSIG250 = 250 PSIG500 = 500 PSIGStep 2Element pressure (PSIG) range Each sensing element has a maximum PSIG rating. Ensure that your system will not exceed this rating to avoid clipping any readings before the device calculates the differential pressure.Step 3How many PWS sensing elements do I need? It takes a pair (2) of PWS elements with the same PSIG rating per (1) PW transmitter. ORDERING TRANSMITTERStep 5Transmitter range After selecting the proper pair of PWS elements, select the PW10 or PW20 transmitter based on the PSID selectable range scale that best fits your application.
