Modular analyzers

-- Control Engineering, 8/1/2001

Racine, Wis. - Q45 analyzers feature modular construction for its line of microprocessor-based transmitters for pH, ORP, conductivity, and dissolved oxygen. The multi-purpose instrumentation platform is said to allow easy implementation of portable, loop-powered, or line-powered analyzer capability with the same instrument. The standard instrument can be rapidly converted between any of the following versions with no requirement for software change:

• Standard loop-powered (16-35 Vdc) transmitter, 4-20mA output;
• 9 V battery operated portable version for view-only measurement;
• Single output, 115/230 V ac line-powered transmitter;
• 115/230 V ac analyzer, dual relay, dual 4-20 mA outputs.
