PMC Smart Electronic Pressure Transmitters (SMT PT/EL) combine state-of-the-art temperature compensated capacitive sensor technology with icroprocessor-based electronics to provide remote digital communications using a HART® protocol communicator. Using the HART® communicator, the transmitter can easily and remotely be configured for specific ranges, calibrated, and tested. The transmitter provides a two‑wire 4-20 mA output.
The SMT PT/EL transmitters accurately measure pressure, level, and vacuum ranges in processes where clogging of the diaphragm face is a particular concern. The small, 1½” diameter of the transmitter allows installation flush with the inside wall of pipes 3″ in diameter and larger. This feature eliminates the usual pocketing problems encountered with conventional flange-mounted and recessed-diaphragm transmitters. The high precision capacitive ceramic sensor is ideally suited for high-wear applications. The SMT PT/EL Series of transmitters offers overpressure protection of up to 10 times the full scale range. The CV configuration allows customers to specify custom lengths of cable to be supplied with the transmitter. A choice of vented Polyurethane or Teflon FEP cable is available. Teflon FEP cable offers improved chemical resistance for more demanding applications.
