EXAxt ZR series - The Next Generation of Zirconia Oxygen/Humidity Analyzers and Detectors

Yokogawa Corporation of America is pleased to introduce the next generation of Zirconia Oxygen / Humidity measurement products. The EXAxt ZR series Zirconia products are developed from the well-proven ZA8 / ZO21 series of instruments. These new, simple and innovative products help conserve energy and control emissions to ensure a cleaner, safer environment.

The EXAxt ZR products are designed for dependable and accurate oxygen concentration measurements for process control and monitoring. Ideal for use in boilers, kilns, furnaces, and process heaters, the enhanced ZR products offer the same simple and intuitive user-friendly operation expected from Yokogawa equipment.

The EXAxt ZR product's interactive touch-screen display, simultaneous measurement of three separate parameters, field rebuildable modular design and HART® communications, have again raised the bar of excellence for the industry standard of in-situ flue gas measurement. Developed from the field proven ZO21D zirconia probe technology, the EXAxt ZR22 in-situ type Zirconia detector provides dependable and accurate oxygen and humidity measurement. Available in lengths from 15 cm to 5 meters, the ZR22 can be used in process temperatures up to 700ºC and pressurized ducts up to 2.5 bar with the pressure compensating option.

The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process. The new probe's modular design incorporates a rebuildable heater and thermocouple assembly, the industry standard Yokogawa Zirconia cell, and removable reference and calibration lines to create an oxygen measurement product designed for simple, quick and low-cost field maintenance.

The EXAxt ZR402 analyzer is the industry's newest and most advanced remote mounted Zirconia oxygen analyzer. The ZR402 captures all the dependability and functionality of the Yokogawa ZA8C oxygen analyzer. Functions such as automatic calibration control, sensor diagnostics, and efficiency calculations are standard with this product. It also features the industry's latest technological advances such as, easy-to-read, simple-to-use, LCD touch screen operation; real-time trend graphing of process variables; two user configurable analog outputs; and, three user configurable measurement parameters including oxygen concentration, relative humidity, dew point, and moisture content.

The EXAxt ZR202 transmitter/detector combines benefits of the ZR402 remote analyzer and the ZR22 detector into an intelligent, rebuildable, low-cost measurement device for in-situ flue gas measurement. This smart probe features a local LCD display and infrared push-button operation for local adjustment of the instrument and calibration control. HART communication protocol allows easy configuration of the instrument as well as up to the second information on all process variables and diagnostic tools. The Yokogawa ZR202 smart probe offers customers a lower cost of product ownership by significantly reducing installation costs from tubing, wiring and conduit.
