PT100 probe, heavy duty insertion, 1 m

The Pico SE016 PT100 Heavy-Duty Insertion Probe, 1 m is designed for engineering, laboratory and industrial applications that require a robust insertion-style temperature probe with a higher maximum temperature than Pico's standard Class A insertion probe.

• Temperature Range: −60 °C to +500 °C
• Probe Length: 150 mm
• Probe Diameter: 4 mm
• Cable Length: 1 m
• Probe Material: Stainless steel
• Cable Material: PVC
• Wiring: 4-wire
• Connector: 4-pin mini-DIN
• Handle: Yes

Heavy-Duty Insertion Temperature Measurement

The SE016 is specifically designed by Pico for heavy-duty insertion applications.

Its 150 mm stainless-steel sensing probe can be positioned in suitable insertion points where direct temperature measurement is required.

Potential applications include:

• Industrial temperature testing
• Engineering development
• Equipment temperature measurement
• Laboratory experiments
• Product thermal validation
• High-temperature test systems
• Research and development
• Long-duration temperature logging
• Process-development testing

The probe should only be used where its dimensions, materials and specified temperature range are appropriate for the measurement environment.

Wide −60 °C to +500 °C Temperature Range

The manufacturer-specified measurement range is:

• Minimum temperature: −60 °C
• Maximum temperature: +500 °C

This wide range allows the SE016 to be used for both sub-zero and elevated-temperature measurements.

Its +500 °C upper limit is substantially higher than Pico's standard SE015 Class A insertion probe, which is rated to +250 °C.

This makes the SE016 a more appropriate choice when high-temperature capability is more important than Class A sensor accuracy.

Class B PT100 Accuracy

The SE016 uses a Class B PT100 sensing element.

Pico specifies:

• Accuracy Class: Class B
• Accuracy: ±0.3 °C at 0 °C

The Class B tolerance is suitable for many engineering and industrial temperature-monitoring applications.

For measurements requiring tighter accuracy at lower temperatures, a Class A or 1/10 DIN PT100 probe may be more appropriate.

PT100 Platinum Resistance Measurement

The SE016 uses a PT100 platinum resistance thermometer.

PT100 sensors determine temperature from the predictable change in electrical resistance of platinum.

They are widely used in:

• Industrial instrumentation
• Laboratory measurements
• Temperature data logging
• Process development
• Engineering testing
• Research applications

The standardized resistance-versus-temperature relationship makes PT100 sensors suitable for repeatable temperature measurement when paired with compatible instrumentation.

150 mm Stainless-Steel Probe

Pico specifies the SE016 probe dimensions as:

• Probe length: 150 mm
• Probe diameter: 4 mm

The probe is manufactured from:

• Stainless steel

The 150 mm sensing stem provides useful insertion reach, while the 4 mm diameter should be considered when designing:

• Test fixtures
• Probe openings
• Equipment access points
• Measurement ports
• Insertion locations

Important 1 m Specification Clarification

The SE016 should not be described as having a 1 m insertion probe.

Pico specifies:

• Probe length: 150 mm
• Cable length: 1 m

The “1 m” in the product name refers to the cable length, not the stainless-steel sensing stem.

This distinction should be clearly maintained on the product page to avoid misleading technical information.

1 m PVC Cable

The probe is supplied with a:

• 1 metre cable
• PVC cable material

The cable provides separation between the insertion point and the connected temperature data logger.

Because Pico specifies the cable material as PVC, the entire cable should not automatically be assumed to tolerate the same +500 °C temperature as the sensing probe.

The complete installation should therefore account for the temperature exposure of the probe, handle, cable and connector.

Four-Wire PT100 Construction

The SE016 uses a:

• 4-wire connection

Four-wire resistance measurement allows a compatible instrument to compensate for resistance in the sensor leads.

This is valuable in PT100 measurements because even small amounts of lead resistance can contribute to temperature-measurement error.

The four-wire configuration therefore provides a suitable interface for precision PRT instruments such as the Pico PT-104.

4-Pin Mini-DIN Connector

The SE016 is fitted with a:

• 4-pin mini-DIN connector

This allows direct connection to compatible Pico PRT temperature data loggers.

The physical connector should be described separately from the sensor's accuracy classification:

• Accuracy Class: Class B
• Connector: 4-pin mini-DIN

Integrated Handle

Pico specifies:

• Handle: Yes

The handle makes it easier to position, insert and remove the probe during suitable engineering and laboratory measurements.

This distinguishes the SE016 from fixed high-temperature probes such as the SE041, which Pico supplies without a handle.

Recommended for Pico PT-104

Pico Technology lists the SE016 as a recommended accessory for the PT-104 High-Accuracy Temperature Data Logger.

The PT-104 supports:

• PT100 sensors
• PT1000 sensors
• Four temperature channels
• Four-wire PRT measurement
• High-resolution temperature logging

Using SE016 probes with the PT-104 provides a suitable system for:

• Multi-point high-temperature logging
• Engineering validation
• Industrial temperature monitoring
• Laboratory experiments
• Product thermal testing
• Research and development

Up to four SE016 probes can be connected directly to one PT-104 for simultaneous four-point temperature measurement.

Heavy-Duty vs Standard Insertion Probe

Pico offers both the SE016 heavy-duty insertion probe and the SE015 Class A insertion probe.

The SE016 is better suited where:

• Temperatures may exceed +250 °C
• A +500 °C upper measurement range is required
• Heavy-duty insertion use is required
• Class B accuracy is sufficient

The SE015 is more suitable where:

• Temperatures remain below +250 °C
• Class A accuracy is preferred
• A slightly smaller insertion probe is advantageous

Complete Measurement Accuracy

The published ±0.3 °C at 0 °C specification applies to the SE016 sensor.

The total measurement uncertainty of a complete system may also depend on:

• Data logger accuracy
• Sensor tolerance at the actual temperature
• Insertion depth
• Thermal contact
• Temperature gradients
• Measurement environment
• Calibration status

For precision applications, the complete probe-and-data-logger measurement chain should therefore be evaluated.

• Heavy-duty insertion temperature measurement

• Equipment thermal monitoring
• Product-development testing
