Process M400 2-Wire Transmitter
- for Hazardous Area Applications across the Chemical Industries
Intelligent Sensor Management (ISM), global hazardous area approvals and the rugged design of the M400 2-wire transmitter series provide outstanding operating reliability and process safety. These features ensure the M400`s suitability for use across the chemical industries. Easiest handling and on-site or remote access over HART to advanced ISM predictive diagnostics tools leads to reduced operating costs and increased process uptime.
The M400 2-wire transmitter is a single-channel, multi-parameter unit for pH / ORP, oxygen and conductivity measurement. Thanks to the mixed-mode input, which allows the use of analog or ISM sensors, the M400 2-wire offers a unique and smooth transition from analog to digital technology.
