THE Servomex Group has announced the availability of Modbus digital communications on the company's 2200 oxygen analyser.
The 2200 analyser consists of a paramagnetic oxygen measurement transmitter and a separate microprocessor-based control unit capable of accepting inputs from up to six transmitters for a wide range of oxidation control and other process oxygen measurement requirements.
Launched as a complementary product to the extremely successful Servomex 1100A oxygen analyser, the 2200 provides digital data communications to mainframe production control computers and offers all the key features needed by current and projected process plant technology.
The addition of Modbus interface capability gives the 2200 a much wider range of digital communications capabilities.
The Modbus protocol is used to establish master-slave/clientserver communication between intelligent devices and is the most widely used network protocol in the industrial manufacturing environment.
Modbus can be used to monitor and program devices and to monitor field devices using PCs and HMIs. The addition of Modbus capability makes it possible for Servomex 2200 oxygen analyser to be routinely interrogated by production or health and safety computer control systems.
The transmitter is certified for use in zone 1 / division 1 hazardous areas with a choice of control units suitable for either zone 1 / division 1 or zone 2 / division 2 areas. The instrument can be used with flammable gas samples, including hydrogen.
Other important features of the 2200 paramagnetic oxygen measurement transmitter include an intrinsically safe 4-20mA output with inputs for external pressure compensation and background gas cross interference compensation as standard.
Specific inputs are available for use with external flow alarms with intrinsically safe supplies for inductive proximity/ring sensors (complying with BS EN 50227, DIN 19234 and NAMUR requirements) and NAMUR
status relays are available as standard.
Options include internal pressure compensation and the ability to handle sample flow rates of up to 1.0L/min.
Key features of the xendos 2200 control unit include autocalibration functions that can be used in conjunction with either optional relays or data communications.
There is also an enhanced 'intuitive' user interface which makes the analyser easier to set up and use in any of three languages (English, French or German).
