Overview

1.1 About This Product
This product is a control device that drives and controls the oxygen sensor in an oxygen analyzer that uses a limiting current type zirconia oxygen sensor, and is responsible for concentration calculation and output. It is used in combination with our oxygen sensor (transmitter). Since the oxygen sensor of this analyzer does not require pretreatment of the measurement gas, it is smaller and has a faster response speed than conventional sampling-type devices equipped with a pretreatment device. In addition, since calibration can be performed using only “instrumentation air” using compressed air, which is commonly found in factories and ships, there is the advantage of not needing to install or manage standard gas cylinders.

1.2 Products and Accessories

Installation

3 Installation
This product is a device that controls Oxygen Sensor and calculates and outputs concentration. In order to measure the oxygen concentration, connect our company’s zirconia Oxygen Sensor and use it by constructing piping related parts. A typical system configuration example is shown below.
3.1 System Configuration Example
Note
Confirm the delivery specifications for scope of delivery and actual system configuration.

3.1.1 System Configuration Example 1
This system is an example of using “TF-10 Probe Transmitter” as an oxygen sensor to measure the oxygen concentration in flue gas from a boiler, etc. Manually operated valves such as needle valve and ball valve are used for calibration gas lines. At the time of calibration, after manually operating the valve to supply the calibration gas, calibration is executed by key operation on the receiver. Use instrument air or atmospheric gas for calibration. Calibration using standard gas cylinders such as zero gas and span gas is not required.

3.1.2 System Configuration Example 2
This system is an example of using “TF-10 Probe Transmitter” as an oxygen sensor to measure the oxygen concentration in flue gas from a boiler, etc. A solenoid valve is installed in the calibration gas line, and the contact output of the receiver is used to open and close the solenoid valve. Calibration can be performed by methods such as “receiver key operation”, “contact input”, and “receiver internal timer”. Use instrument air or atmospheric gas for calibration. Calibration using standard gas cylinders such as zero gas and span gas is not required.

3.1.3 System Configuration Example 3

This system uses a TF-III type probe transmitter as an oxygen sensor, to measure the oxygen

concentration in high-temperature flue gas in a heating furnace. In addition to calibration gas piping,

ejector air piping and purge air piping are used. Since the calibration gas and purge air are operated by

opening and closing the solenoid valve using the contact output of the receiver, calibration and purge

can be performed by methods such as “receiver key operation”, “contact input”, and “receiver internal

timer”. Use instrument air gas for calibration. Calibration using standard gas cylinders such as zero

gas and span gas is not required. The TF-III type probe transmitter uses a separate power supply

and temperature control device for heating and keeping warm in order to prevent dew condensation in

the sampling section.

3.4.3 Wiring Method When Replacing from DTF-101 Receiver
DTF-101 receiver and DTF-102 receiver differ in the number of contact input/output points and the content corresponding to each terminal symbol. When replacing DTF-101 with this product(DTF-102), connect the wiring referring to the following.
Power line / Analog output line
There is no change. Connect to terminals with the same terminal symbol as the DTF-101 receiver.
Contact input line / Contact output line
Use “3.4.4 Wiring Confirmation Sheet When Replacing from DTF-101 Receiver” to connect contact input and contact output wiring. Here are the steps:
1. Check the input/output settings of the existing receiver
Check the contact input and contact output details from t product number (CAT NO.) of DTF-101 receiver. The product number is indicated on the rating plate of the receiver. (The rating plate is pasted on the inside of the door.)
2. Check the input/output you are actually using
Check the terminal symbols that are actually wired to the terminal block of the DTF-101 receiver. Enter the input/output items in the columns of “Used contact input items” and “Used contact output items” only for the terminals that are wired. Even if contact input/output is set, there is no need to wire the replacement receiver (DTF-102) because the terminals that are not actually wired are not used.
3. Check the input/output settings of the DTF-102 receiver
Check the contact input and contact output contents from the replacement receiver (DTF-102) product number (CAT NO.). Described in the “DTF-102 contact input setting” and “DTF-102 contact output setting” columns.
4. Relocate the wiring to the corresponding terminal on the DTF-102
receiver
Move the wiring to the terminals of the DTF-102 receiver that have the same items as the “contact input items in use” and “contact output items in use”.

5.1 About Calibration
In order to correctly measure oxygen concentration, perform gas calibration using the reference gas (hereinafter referred to as calibration) in following cases.
When using analyzer for the first time. After replacing the oxygen sensor. Periodic inspections.
Recommended calibration cycle Air-Point Calibration1/month

Remark Warms up sufficiently before Calibration.
Warm-up time as a guideApprox. 2 hours

5.2 Calibration Point and Calibration Type

5.2.1 Calibration Point Type
Oxygen analyzers using our limiting current type zirconia oxygen sensor can perform measurement only by calibrating the air point. Normally, it is used for 1-Point Calibration with the calibration point as the air point. For the air point, use “instrument air”, “atmosphere”, or “standard gas with atmospheric equivalent concentration”. Other calibrations are performed to further improve accuracy for specific gas concentrations, or when accuracy confirmation and calibration using standard gases are required.

Purging

6 Purging

6.1 About Purging
Purging is the process of blowing compressed air to remove dust and other foreign matter (hereafter referred to as dust) that has entered or deposited in the measurement gas flow path around the oxygen sensor or inside the sampling probe. If dust is contained in the sample gas, purge as necessary to reduce dust accumulation and clogging. In addition, continuous purging prevents dust from entering the measurement gas flow path, so it is possible to protect the oxygen sensor and measurement gas flow path during periods when measurements are not performed. This product can configure a system that performs semi-automatic or automatic purging by opening and closing the solenoid valve installed in the flow path of compressed air for purging with contact output.

6.2 Purge Method Type

This product can purge by the following two methods. When changing the purge method, it is necessary to change the CH data setting. Normally, we set the purge method according to the customer’s usage at the time of shipment.

7.4 Sleep Mode

7.4.1 About Sleep Mode

Sleep mode is a function that protects the oxygen sensor and measurement gas flow path from exhaust gases by continuously supplying purge air while the oxygen sensor is not driven. There are cases that non-driving oxygen sensor, measurement gas flow path and transmitter are exposed to exhaust gas and residual gas in the furnace, when combustion equipment is stopped for a long period of time due to installation, test, inspection or repair. While the sensor is in driving, the zirconia oxygen sensor is durable against dirty gases such as exhaust gas. However, when the sensor is not driven (low temperature), If exposed to dirty gas such as exhaust gas or residual gas in the furnace, the sensor will deteriorate in a short period of time and may not be able to measure. In addition, dust accumulation and clogging may occur in the sample gas flow path. In sleep mode, the oxygen sensor is not driven, and purge air is continuously supplied to protect the oxygen sensor and measurement gas flow path from exhaust gas. When performing continuous purging automatically using the sleep mode, a system is required to operate the solenoid valve as shown in “3.1.2 System Configuration Example 2” or “3.1.3 System Configuration Example 3”.

7.4.2 Switch to Sleep Mode and Operation
