Description
“Ji” Japsin Instrumentation Industrial Heavy Duty Leaf Type Thermocouple – 0 to 800°C, 12-Inch Probe
The “Ji” Japsin Instrumentation Industrial Heavy Duty Leaf Type Thermocouple is designed for temperature measurement in industrial processes, machinery, manufacturing operations, and applications where direct contact temperature sensing is required. With a temperature measuring range of 0 to 800°C, this thermocouple is suitable for compatible high-temperature applications that require a portable or manually positioned temperature sensor.
The instrument features a 12-inch probe, a 4-inch handle, a yellow connector, and a 1-metre cable. Its leaf-type probe configuration is designed for temperature sensing at suitable contact points, depending on the application and probe construction. The handle provides a convenient gripping area for positioning the sensor, while the cable and connector allow it to be connected to a compatible temperature indicator, controller, or measuring instrument.
Thermocouples operate on the thermoelectric principle, generating a small voltage in response to a temperature difference between two dissimilar metal conductors. A compatible temperature measuring device interprets this voltage and displays the corresponding temperature. This makes thermocouples a widely used solution for industrial temperature measurement, particularly in applications involving elevated temperatures.
The “Ji” Industrial Heavy Duty Leaf Type Thermocouple is intended for users who need a practical temperature sensing arrangement with an extended probe, a handling grip, and a cable connection. It can be considered for suitable industrial inspection, maintenance, and process-monitoring applications, subject to the sensor element, probe material, and measurement requirements.
Key Features and Benefits
1. Temperature Range of 0 to 800°C
The thermocouple is specified for a temperature range of 0 to 800°C, making it suitable for compatible high-temperature measurement applications. This range can support temperature checks in industrial equipment, heated surfaces, production processes, and other applications where temperatures may reach elevated levels.
The actual usable temperature range depends on the thermocouple element type, sheath or probe material, exposure conditions, and measurement duration. Confirm the sensor type and manufacturer’s operating limits before using the instrument at the upper end of the range.
2. Heavy-Duty Leaf-Type Probe
The instrument features a leaf-type sensing probe designed for suitable contact temperature measurement. The probe configuration can be useful where a particular contact area or surface needs to be checked, depending on the probe geometry and intended application.
The heavy-duty design is intended for industrial use. However, the probe should be handled according to the manufacturer’s instructions to avoid bending, impact damage, or exposure to conditions beyond its specified limits.
3. 12-Inch Probe Length
The 12-inch probe length provides an extended reach for accessing measurement points that may be difficult to reach with shorter sensors. It can be useful when checking temperatures on equipment, components, and surfaces where additional clearance is required between the operator’s hand and the measurement point.
The probe should be positioned correctly to establish suitable thermal contact. Measurement response and accuracy depend on contact quality, probe construction, surface condition, and the measuring instrument used.
4. 4-Inch Handle for Convenient Handling
The thermocouple is supplied with a 4-inch handle that provides a gripping area for positioning and handling the probe. The handle helps the operator maintain control while placing the sensing end at the required measurement location.
During operation, the handle should remain within its specified temperature limits. Avoid exposing the handle or cable to excessive heat, flames, or hot surfaces unless the manufacturer specifically approves such use.
5. Yellow Connector for Instrument Connection
The instrument is supplied with a yellow connector for connection to a compatible thermocouple input. The connector allows the sensor to be connected to an appropriate temperature indicator, digital thermometer, or temperature measurement device.
Connector colour alone should not be treated as confirmation of thermocouple type because colour conventions can vary by standard and manufacturer. Always verify the thermocouple type, polarity, and connector compatibility before connecting the sensor.
6. 1-Metre Cable
The thermocouple includes a 1-metre cable to connect the probe assembly to the measuring instrument. This provides flexibility when positioning the sensor and connecting it to a nearby temperature display or measurement device.
For reliable readings, the cable should be compatible with the thermocouple element and extension requirements. Avoid routing it near high-temperature surfaces, sharp edges, or sources of electrical interference unless the cable is designed for those conditions.
7. Thermoelectric Temperature Measurement
The thermocouple uses the thermoelectric effect to measure temperature. When two dissimilar metal conductors are joined and exposed to a temperature difference, a small voltage is generated. The connected measuring instrument interprets this voltage to determine the temperature.
This operating principle allows thermocouples to measure a wide range of temperatures and makes them suitable for many industrial applications. The exact measurement characteristics depend on the thermocouple type and the compatibility of the connected instrument.
Working Principle of a Thermocouple
A thermocouple consists of two dissimilar metallic conductors joined at the sensing junction. When the junction experiences a temperature different from the reference junction, a thermoelectric voltage is generated. This voltage changes according to the temperature difference and the thermocouple material combination.
A compatible temperature indicator or measuring device converts the generated voltage into a temperature reading. Correct thermocouple type selection, polarity, extension cable compatibility, and reference-junction compensation are important for obtaining reliable readings.
Industrial Applications
The “Ji” Japsin Instrumentation Industrial Heavy Duty Leaf Type Thermocouple can be considered for compatible applications such as:
- Manufacturing industries: Temperature checks during industrial production and processing.
- Maintenance inspections: Measuring temperatures at accessible equipment and component surfaces.
- Heating systems: Monitoring suitable high-temperature equipment and assemblies.
- Industrial machinery: Checking temperatures at designated measurement points.
- Metalworking applications: Temperature measurement in compatible processes and equipment.
- Process industries: Temperature monitoring where a suitable contact probe is required.
- Equipment testing: Checking temperature conditions during inspection and troubleshooting.
Application suitability depends on the probe construction, thermocouple type, process temperature, contact conditions, and the connected measuring instrument.
Installation and Usage Recommendations
Before use, confirm the thermocouple type and ensure that the connected temperature indicator supports the same sensor type. Check connector polarity and compatibility before connecting the sensor.
Position the leaf-type probe at the intended measurement point and allow sufficient time for the reading to stabilize. The required contact time depends on the surface, probe construction, and temperature difference. Do not exceed the specified temperature limits of the probe, handle, connector, or cable.
After use, allow the probe to cool before storage. Avoid sharp bending, impact, and unnecessary mechanical stress. Periodically inspect the probe, cable, connector, and handle for wear or damage. Follow the manufacturer’s instructions for cleaning, calibration, and maintenance.
