  Description

1500 Smart Transmitter

Precision Instruments for Pressure, Flow, Temperature, and Level

Meriam’s 1500 Digital Transmitters are for high accuracy applications for OEM’s, on manufactured skids, in process control systems and plant instrumentation. RS-485 communications allows for easy configuration using a PC or laptop computer. The RS-485 addressable interface allows up to 32 devices to be networked together. Optional 1-5 Volt or 4 - 20 mA outputs are also configured from a PC or laptop.
