Introduction
Thank you for purchasing the Hioki Z2012-01, Z2013-01, Z2014-01, Z2015-01, Z2016-01, Z2017-01 Heat Flow Sensor. To obtain maximum
performance from the product over the long term, be sure to read this manual carefully and keep it handy for future reference.
(This sensor is calibrated by
DENSO CORPORATION
.)
Verifying Package Contents
When you receive the product, inspect it carefully to ensure that no damage occurred during shipping. If damage is evident, or if it fails to
operate according to the specifications, contact your authorized Hioki distributor or reseller. For information about package contents, see
Accessories listed in Specifications.
Operating Precautions
•
Before use, verify that there is no wiring break in each of the heat flow wires and the temperature wires between the positive and the
negative terminals. A resistance value of 2 kΩ or less between the terminals indicates that there is no wiring break. Although the resistance
value between the terminals may increase depending on the environment, a resistance value of 2 kΩ or less will not have any effect on any
output values.
•
Each sensor has a different sensitivity value.
•
To clean the sensor, wipe it gently with a soft cloth moistened with water.
•
Do not subject the sensor to excessive force during use or storage.
•
The cable may harden during use at temperatures of 0°C or lower.
•
As a result of the sensor’s excellent response characteristics, measured values may fluctuate due to factors such as outdoor airflow and
radiant heat in the surrounding environment. To minimize such fluctuations, see “Limiting measured value fluctuations” below.
•
Although the sensor is waterproof, its tip is not. Exposure of the tip to water droplets may result in rust, malfunction, or failure. Exercise care
to avoid exposing the tip of the sensor to water droplets.
•
In environments in which the sensor is exposed to sunlight and other radiation, output values will include the radiant heat component.
•
The lettering on the mark tubes will fade if subjected to strong rubbing or placed in direct sunlight for an extended period of time. Protect the
mark tubes as necessary.
•
Repair service for this sensor, which is consumable, is not offered.
Affixing the Sensor to the Measurement Target
Secure the sensor so as to keep out any foreign materials or air layer by using Model Z5008 Thermally Conductive Tape. If an object with
thermal resistance comes between the sensor and measurement target, it will be impossible to obtain accurate measured values for heat
flows.
Do not reuse the double-sided tape. If the double-sided tape is reused, it will be impossible to obtain accurate measured values.
You will need: the sensor and Model Z5008 Thermally Conductive Tape (option)
1
Cut the thermally conductive tape to the necessary size and remove the protective backing.
2
Apply the thermally conductive tape to the measurement target and remove the film on the opposite side.
3
Affix the entire back side (the side with the flat surface) and the temperature measuring part of the sensor to the thermally
conductive tape.
4
Heat flow: Connect the yellow (+) and the blue (
) wires respectively to the positive and the negative terminals of the instrument.
Temperature: Connect the green (+) and the white (
) wires respectively to the positive and the negative terminals of the instrument.

When making measurements over an extended period of time or in an environment where the sensor will be subjected to vibration, secure
the cable in place, for example with tape, so that there is no load applied on the heat flow sensor, temperature measuring part, and cable. If
affixing the sensor to a curved surface, secure the heat flow
sensor’s tip and temperature measuring part's tip in place with tape that is no
thicker than 50 μm.
Removing the Sensor From the Measurement Target
Grip the cable near the temperature measuring part and lift up slowly from the tip to peel off the sensor.
(Bending the heat flow sensor or the temperature measuring part excessively or peeling it off violently will
subject it to excessive force, causing it to malfunction or fail.)
Limiting Measured Value Fluctuations
Using the LR8432’s waveform calculation moving average function
This function enables you to simultaneously record the actual input waveform and a waveform obtained by applying a filter to eliminate
fluctuations. For more information, see the LR8432 instruction manual.

使用前的注意事项
•
使用前
,
请确认本传感器的热流与热电偶的正端子和负端子之间没有断线。如果端子间的电阻值为
2 k
Ω
以下，则未断线。
另外，本传感器可能会因环境因素导致端子间电阻值增大，但在电阻值
2 k
Ω
以下的状态下使用时，不影响输出。
•
灵敏度值为各传感器值。
•
去除本传感器的脏污时，请用柔软的布蘸少量的水之后，轻轻擦拭。
•
使用或保管时，请勿向本传感器施加过大的力。
•
在
0
°
C
以下的环境下，电缆会变硬。
•
由于本传感器的响应性良好，因此，可能会受到外部气流或周围辐射热等的影响而导致测量值产生波动。要在抑制波动的状态下进行测量时，
请参照下述“抑制测量值的波动”。
•
本传感器为防水结构，但由于末端部分未采用防水结构，因此，如果进入水滴，则可能会导致故障和事故。使用时，请勿使水滴进入末端部分。
•
在阳光等照射的环境下，会输出包括辐射热在内的值。
•
标号管部分的字符可能会因强力摩擦或长时间曝晒于阳光之下而消失。使用时，请根据需要保护标号管部分。
•
本传感器为消耗品，因此无法修理。
将传感器安装到被测对象上
