1. Product Introduction

The KDW550 smelting thermometer is a high-precision special instrument developed for the smelting and casting industry smelting and other industries to quickly measure the temperature of molten metal.

The instrument is centered on a single-chip microcomputer, uses high-precision measurement sensor parts, and adopts a variety of intelligent processing technologies to ensure the long-term and stable operation of the instrument.

This instrument can be used with a suitable thermocouple to perform precise and rapid temperature measurement in various occasions.

2. Product Features

The KDW550 large-screen smelting thermometer uses a 5-inch digital tube to display: the word height is 128mm. Suitable for long-distance reading and viewing.

This instrument has an alarm function such as electric ringtone sounding prompt function at the end of temperature measurement, automatic temperature measurement value maintenance function, couple break, over-range alarm functions, etc., which are simple and convenient to operate.

Since the latest anti-interference measures are adopted, this instrument has excellent anti-interference ability. The temperature measurement in the furnace can be measuredno need to turn offpower when the medium-frequency furnace is turned on and melted.

This instrument can be equipped with 5 types of thermocouples in the same machine.

This instrument can store 1000 sets of historical data and can be equipped with a printer.

3. Technical performance indicators

1) Measurement range and measurement accuracy

2) Resolution (℃): 1

3) Response time (S): 1

4) Power supply: AC220V + 10%

5) Large screen size: 500×238×90 (mm)

4. Operation Instructions

Turn on the power switch (ON/OFF), the monitor displays " " immediately, and then displays the thermocouple model / is S type, / is B type, / is WRe3/25, / is K type, / is R type,).

When the thermocouple is not plugged in, the instrument displays " ". When the thermocouple is plugged in and the contact is good, the instrument displays ambient temperature (the instrument of the B index number shows " "), and the temperature measurement can be performed at this time. When measuring the temperature, insert the thermocouple into the metal liquid at a depth of ≥20mm to ensure fast, accurate and stable. When the temperature measurement is over, the electric ringing rings, prompting the test gun to be lifted, and the instrument displays and maintains the measured temperature value automatically.

(1) Historical data query

This instrument can store 1000 sets of historical data.

Press the "Query" key and the instrument will enter the historical data query state. At this time, the large screen displays the current year; according to the query needs, press the "↑" and "↓" keys to correct it.

For example: To query such data: the temperature measured at 09:08 on December 10, 2008 was 1678℃;

At this point, query steps:

Press the "Query" key to display the current year; press the "↑" and "↓" key to correct it to display 2008;

Press the "" key again to display the current month, press the "↑" and "↓" key to correct it to display 12;

Press the "" key again to display the current day, press the "↑" and "↓" key to correct it to display 10;

Press the "Confirm" key to display 2008, 1210, 0908, and 1678 in turn;

At this time, press the "↑" and "↓" keys to query the data before and after the temperature value.

If the instrument has no response, it means that the dataqueryhas beenfinished; press the "Query" keys and the instrument will exit the query status.

(2) Print

The printer data cable plug is connected to the printing interface of the large screen monitor. Connect the printer power supply. Every time the large screen displays data, the printer will print the display data automatically. The printing format is as follows (such as 09:08 08:1678℃ on December 10, 2008): 2008-12-10 09:08 1678.

5. Install

Large-screen monitors should be installed within a straight line of 10-50 meters from the temperature measurement point to facilitate observation and recording. The installation position should be 2-4 meters from the ground. The monitor power supply is AC220V (using lighting line power supply, the grounding must be reliable).

6. Supporting kits

1) Test gun: The model of the test gun must match the instrument model, and the specifications are 1.5-2.5m.

2) Electric bell

3) Power cord

4) Quick head

(1) Single platinum-rhodium fast double head KS-602

(2) Single platinum-rhodium fast double head KR-602

(3) Tungsten and rhenium fast double head KW-602

(4) Double Platinum Rhodium Fast Pin-602

5) Optional printer
