Thermocouple high-temp type K exposed tip, fiberglass insulated, 2 m

The Pico SE060 High-Temperature Type K Exposed-Tip Thermocouple, Fiberglass Insulated, 2 m is designed for engineers, laboratories and industrial test environments that require temperature measurement at substantially higher temperatures than standard thermocouple cable assemblies can support.

Pico Technology identifies the SE060 as:

• Order Code: SE060
• Thermocouple Type: Type K
• Junction Type: Exposed
• Accuracy Class: Class 1
• Pico-Quoted Accuracy: ±1.5 °C
• Quoted Class 1 Range: −40 °C to +1000 °C
• Cable Length: 2 m
• Conductor Diameter: 0.8 mm
• Conductor Temperature Rating: Up to +1000 °C
• Insulation: High-temperature glass fiber / fiberglass
• Continuous Insulation Rating: +750 °C
• Primary Application: High-temperature and oven measurements

Pico describes this construction as a robust, economical exposed-junction thermocouple suited particularly to oven-temperature measurement.

High-Temperature Type K Measurement

The SE060 uses a Type K thermocouple, a widely used thermocouple type for engineering, laboratory and industrial temperature measurements.

Pico publishes Class 1 performance over:

• −40 °C to +1000 °C

The 0.8 mm thermocouple conductor itself is rated for:

• Up to +1000 °C

This provides significantly greater high-temperature capability than Pico's standard fiberglass-insulated Type K thermocouple range.

Class 1 Type K Performance

Pico describes SE060 as a Class 1 Type K thermocouple and quotes:

• Accuracy: ±1.5 °C
• Quoted range: −40 °C to +1000 °C

Pico also states that its thermocouples are manufactured to industry tolerances specified by:

• IEC 60584-2:1993
• BS EN 60584-1:2013

For measurement systems requiring formal uncertainty calculations, the applicable thermocouple tolerance standard, data logger accuracy and installation conditions should all be considered.

High-Temperature Fiberglass Insulation

A major feature of SE060 is its high-temperature glass-fiber insulation.

Pico specifies the insulation for:

• Continuous operation at +750 °C

This is an important distinction from the +1000 °C conductor rating. The complete cable assembly should not automatically be treated as continuously rated to +1000 °C.

0.8 mm High-Temperature Conductor

The SE060 uses a:

• 0.8 mm conductor

Pico specifies the conductor as suitable for:

• +1000 °C

The larger high-temperature conductor is one of the key differences between SE060 and Pico's standard SE030 2 m fiberglass-insulated Type K thermocouple.

Exposed-Junction Construction

SE060 uses an exposed thermocouple junction.

With the sensing junction directly exposed to the measurement environment, there is less thermal mass around the junction than with a sheathed probe.

Pico notes that exposed-tip thermocouples provide a very fast response and are particularly suited to gas-temperature measurements.

Potential applications include:

• Oven atmosphere measurement
• Heated-air monitoring
• Gas-temperature testing
• Thermal chamber measurements
• Laboratory heating experiments
• High-temperature R&D

Important Limitation for Exposed Junctions

Because the thermocouple alloys are exposed, Pico states that exposed-tip thermocouples should not be used in corrosive or oxidizing liquids.

For those environments, an appropriately protected or sheathed thermocouple should be selected.

2 m Cable Length

The SE060 provides:

• Cable length: 2 m

Pico's latest TC-08 datasheet confirms the high-temperature Type K family as:

• SE059: 1 m
• SE060: 2 m
• SE061: 3 m
• SE062: 5 m

The longer 2 m SE060 provides more separation between the high-temperature measurement point and the connected data logger than the SE059 1 m version.

Fixed High-Temperature Installation

Pico notes that when the thermocouple is fixed in position so that the insulation is not repeatedly flexed, the assembly can operate more effectively in demanding high-temperature environments.

For high-temperature installations:

• Minimize unnecessary cable movement
• Avoid repeated flexing of hot fiberglass insulation
• Keep the measurement layout stable
• Route the cable away from mechanical damage
• Respect the +750 °C continuous insulation limit

Recommended for Pico USB TC-08

Pico lists the SE060 as a recommended accessory for the USB TC-08 Thermocouple Data Logger.

The TC-08 provides:

• 8 thermocouple inputs
• Type K support
• Built-in cold-junction compensation
• 20-bit measurement resolution
• PicoLog Cloud software
• Multi-channel temperature recording

Several SE060 thermocouples can therefore be used for multi-point high-temperature monitoring.

Oven Temperature Monitoring

Pico specifically identifies this high-temperature thermocouple construction as ideal for oven temperatures.

Typical oven-testing applications include:

• Temperature profiling
• Heating-cycle monitoring
• Cooling-cycle monitoring
• Product heat testing
• Temperature distribution studies
• Thermal process development
• Laboratory oven validation

High-Temperature Gas Measurements

The exposed junction also makes SE060 suitable for compatible gas-temperature measurements where fast response is valuable.

Potential applications include:

• Heated-air systems
• Oven atmospheres
• Laboratory gas-temperature tests
• Thermal chambers
• Engineering airflow experiments

Pico does not publish a numerical response time for SE060, so no specific response value should be added.

Thermocouple Aging and High-Temperature Use

At elevated temperatures, thermocouple characteristics can change over time.

Pico notes that decalibration can occur when the composition of thermocouple wire is altered by prolonged high-temperature exposure or contamination.

For demanding applications, good practice includes:

• Periodically checking thermocouple condition
• Inspecting fiberglass insulation
• Avoiding contamination
• Checking electrical continuity and resistance
• Replacing sensors showing physical or measurement degradation

• Oven temperature monitoring
• High-temperature air measurement
• Gas-temperature testing
• Thermal chamber testing
• Heat-treatment experiments
• Materials research
• Product thermal validation
• Industrial temperature monitoring
