Servomex 4000C platform gas analysers are now available with Modbus communications.
Servomex 4000C platform gas analysers are now available with Modbus communications.
This benefits customers by improving the ease with which the analysers can be integrated within plants, so reducing installation costs.
For those not yet using a fieldbus, the Modbus-ready 4000C analysers provide a future-proof platform capable of transmitting signals over distances up to 1km.
Three series of gas analyser are built on the 4000C platform: the 4100 is a gas purity analyser for producers and users of industrial gases; the 4200 analyses flammable gas samples for producers and users of industrial gases; and the 4900 is for continuous monitoring of emissions.
All three families of analyser already have an RS232 communications port, and now they also benefit from an RS485 port that is user-configurable for Modbus ASCII or Modbus RTU.
Third party converters are available to convert the Modbus signals to a number of other standards.
The Servomex 4000C platform is renowned for its stability and reliability thanks to its established paramagnetic, zirconia and Gfx (gas filter correlation) infra-red technologies.
Independent long-term tests by multinational gas producers continue to confirm the class-leading performance.
For customers who already have a gas analyser based on the 4000C platform, an upgrade path is available.
