Software improvements allow for selectable test functions including frequency generator and programmable current outputs. Each transmitter offers optional HART communication protocol for monitoring and programming. Additional benefits include: options for remote mounting; 4-20mA and frequency outputs; seamless thread-in installation; flexible mounting with 360-degree rotation; and NEMA 4X weather-proof enclosure. – awgearmeters.com
