Yokogawa ZR802G|01|-t-t 1/2 NPT Zirconia Oxygen Humidity Analyzer Converter

The Yokogawa ZR802G is an intelligent online zirconia oxygen content monitoring instrument from Yokogawa Electric. The following is the specific introduction:

Yokogawa ZR802G|01|-t -t 1/2 NPT is a specific model in the Yokogawa ZR802G series, and its technical parameters are as follows:

Measurement range

Oxygen (O₂): 0.01-100 vol%

Water vapor (H₂O): 0-100 vol%

Accuracy

Repeatability: O₂ is ±0.5%FS in the range of 0-5 vol%; ±1%FS in the range of 0-25 vol% and above to 0-100 vol%. H₂O is ±1 vol% H₂O at a sample gas pressure of 2kPa or less.

Linearity: O₂ ±1%FS in the range of 0-5 vol%; ±3%FS in the range of 0-25 vol% to 0-50 vol%; ±5%FS in the range of 0-50 vol% and above to 0-100 vol%. H₂O ±2 vol% H₂O within ±0.49kPa of sample gas pressure; ±3 vol% H₂O at sample gas pressure of 2kPa or below.

Drift: O₂ zero and span drift are both ±2%FS/month; H₂O zero and span drift are both ±3 vol% H₂O/month.

Response Time: 90% response is achieved within 5 seconds.

Digital communication: This model itself does not explicitly come with a special communication protocol, but the entire ZR802G series supports HART 7, Ethernet (Modbus TCP), RS-485 (Modbus RTU).

Converter interface: t 1/2 NPT, used to connect related pipes or equipment, etc.

The Yokogawa ZR802G is a model in its own right, with subdivided models underneath. Depending on the configuration options, it can be subdivided into the following models:

**By converter interface**: ZR802G|01|-t-t 1/2 NPT, indicating a converter with a t1/2 NPT interface.

**By digital communication method**: ZR802G|02|-t

- ZR802G|02|-h-h HART, indicates that the HART communication protocol is used.

- ZR802G|02|-e-e HART+Modbus TCP, indicates that HART and Modbus TCP communication protocols are supported.

- ZR802G|02|-m-m HART+Modbus RTU, indicates support for HART and Modbus RTU communication protocols.

**Press other options**

- ZR802G|03|-n-n always-n and ZR802G|04|-n-n always-n, the exact meaning is not clear at this time, but it is presumed to be related to some default configurations or specific functions.

- ZR802G|001|/sct /sct indicates an analyzer with a stainless steel label plate.

- ZR802G|005|/rc/rc indicates an analyzer with a ruggedized coating (epoxy + polyurethane coating).

- ZR802G|006|/br/br indicates a wall bracket for ZR402G replacement.
