MS2701E High Resolution ER Transmitter

RS-485 Modbus Output

Metal Samples’ new compact MS2701E ER Transmittermeasures all types of electrical resistance (ER) corrosionprobes. The new high-resolution, 16-bit measurementprovides faster response, obtaining corrosion rates in hoursinstead of days.

The transmitter is provided in a weather-proof (IP 66 / NEMA-4X)and explosion proof cast aluminum enclosure. It is designedto be mounted directly to the probe, but can also be mountednearby using the optional mounting kit and a customer-supplied mounting pole.

The MS2701E transmitter offers simple installation and robustRS-485 Modbus communication, allowing up to 32 units to beconnected in series (daisy-chained) on a single line. Setup is also simple, using a set of switches to select the probe type to bemeasured, address, and other options.
