Field Instruments · Analyzers · Components · Test & Measurement
Controsys is now a distributor of four Yokogawa product ranges: OpreX Field Instruments, OpreX Analyzers and OpreX Components from Yokogawa Electric Corporation, and test and measurement instruments from Yokogawa Test & Measurement Corporation.
That covers the measurement chain end to end — DPharp pressure transmitters, flowmeters and temperature transmitters in the field; gas and liquid analyzers for process chemistry; JUXTA signal conditioners, surge arresters and power monitors in the panel; and power analyzers, oscilloscopes, data acquisition and calibrators on the bench. Controsys supplies, specifies and supports the range, and integrates it with the annunciator, mimic and control panels we build.
Controsys also provides maintenance and calibration services for Yokogawa products — so instruments stay accurate and in service long after commissioning. See the full product range or the Controsys home page for our panel-building services.
