MS2801E Ultra Resolution ER Transmitter

RS-485 Modbus Output

User's Manual in PDF
Instrinsic Safety Certifications
Metal Samples’ new compact MS2801E Corr Velox ER Transmitter measures all types of electrical resistance (ER) corrosion probes. The ultra high-resolution, 20-bit measurement provides faster response, obtaining corrosion rates in hours instead of days.

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

The Corr Velox transmitter offers simple installation and robust RS-485 Modbus communication, allowing up to 32 units to be connected in series (daisy-chained) on a single line. Setup is also simple, using a set of switches to select the probe type to be measured, address, and other options.
