MS2700E High Resolution ER Transmitter

RS-485 Modbus Output

Metal Samples’ new compact MS2700E ER Transmitter measures all types of electrical resistance (ER) corrosion probes. The new high-resolution, 16-bit measurement provides faster response, obtaining corrosion rates in hours instead of days. The transmitter can be remote or direct-mounted (shown).

The transmitter is available in a weather-proof (IP66) stainlesssteel enclosure designed for applications which do notpermit aluminum enclosures (such as offshore environmentsor Zone 0 hazardous areas). Alternatively, a weather-proof(IP66) and explosion proof cast aluminum enclosure is also available.

The MS2700E 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.
