Dwyer PMT2-03-A-U2 is a Particulate Transmitter with a temperature range of -40 to 145°F (-40 to 63°C) for ambient and -40 to 248°F (-40 to 120°C) for process. It offers an accuracy of ±5% of reading and requires 12 to 28 VDC power. It has an enclosure rating of UL Type 4 (IP66) and ATEX/IECEx IP65. The transmitter has a 4 to 20 mA output signal and two 1/2" female NPT conduit openings for electrical connections. Its wetted materials include 316L SS, silicone, and PTFE. It can detect particulates of 0.3 microns and higher with a detection range of 5 to 5000 pA. The transmitter can be mounted in any orientation and has a pressure limit of 30 psi (2 bar). It features a removable terminal block for easy wiring (16 to 20 AWG wire) and has a powder coated aluminum enclosure. The PMT2-03-A-U2 is suitable for air and compatible gases, and is ideal for monitoring air quality.
