Instruction Manual
ITEM: PRESSURIZED THERMOMETER
MODEL : T230 SERIES

Please read instructions carefully prior to using the instrument for proper and safe operations.
Mishandling could cause device malfunctions and result in disastrous injuries or accidents.
1. Do not exceed the temperature range allowed.
2. Do not apply excessive load, vibration or impact.
Damaged or ruptured product may cause temperature measurement deviations.
3. Please use within the specified temperature ranges.
Exceeding the temperature range may cause disruption in nearby area
due to failure of or damage to the temperature indicator.
4. Do not mount the temperature sensor directly on the pipes. Please use a protective tube.
5. Please always follow the mounting tips in the manual in cases of field installation.
6. Do not make any modifications to the product or to add more functions.
Please consult with us for any repair.

CONTENTS

1. Overview
This is a thermometer measuring temperature using pressure. It can be put to use immediately
after installation. It is used when it is necessary to place mearusing and indicating parts separately
Please read the user manual carefully and thoroughly before using the product
for proper and safe operations.
2. Application
This thermometer may indicate spedified temperature to indentify temperature within
the processing control or pipes for more stable control.

Operation Principles
Fluid filled pressurezed thermometer shown in ② consists of sensing bulb, indicator
and connecting capillary tubes (③). There is a connector to bulb between the capillary
tubes. Fluid within either expands or contracts accordly to temperature change.
The pressure difference is transferred to Tourdon Tube through the capillary tube and
its change amount is conveted into temperature on the indicator.

C. Temperature compensation
Operation principles
Actual temperature measurement can fluctuate
due to temperature rate of each state. In order to
display accurate temperature, two Bimetal are
there to compensate in the amount of Bourdon
tube change ratio caused by its surrounding
environemnt.
7. Installation
1) Please make sure of any damage present or condition the product is in prior to installation.
2) Temperature deviation may occur depending on how deep the sensor is inserted.
Make sure to insert the temperature sensor completely in order to detect accurate temperatur
e
NO YES
3) This product is sensitive to vibrations and physical impact.
4) Please install the thermometer away from any vibraion or physical impact,
if there is possibility of vibration or impact near its installation area.
5) It is recommended to use thermowell for maintenance.
*Please refer to thermowell manual for its installation and use.

6) Use proper wrench to install.
7) It will cause failure if the casing gets impacts or the capillary tube is bent while being installe
d
Case
Capillary
8) Please protect the sensor bulb since the temperature difference of the sensor bulb and
capillary tube will cause inaccurate temperature measurement.
9) Inspect the installation area to check for moisture, vibration, dust or corrosive gas.
10) Avoid installing in the area which might exceed the specified temperature range.
11) Please protect it from lightning or steam.
12) Avoid installing in direct sun light.
8. Operation instructions
1) Use in 75% of maximum capacity for commercial use.
2) Never use in temperature range in excess of specification.
3) Avoid sudden temperature changes.
4) Check if there is vibration, pulsation or heat in the piping line and use products
with capillary or select proper oil type if necessary.

5) One or two regular inspections in 6 month are recommended to check contact operation or attem
p
6) In case of large deviation of indicator, dismount it to inspect.
7) Main causes are wearing of parts, corrosion or distortion due to external vibration and/or impact.
In this case, the removal of the cause, adjustment, replacement is necessary.
