PT100 probe, general purpose, class A, 2 m

The Pico SE011 PT100 General-Purpose Probe, Class A, 2 m is designed for engineers, laboratories, research teams and industrial users who require reliable PT100 temperature measurement across a broad range of general-purpose applications.

Pico Technology specifies the SE011 as a general-purpose Class A platinum resistance thermometer probe suitable for non-specialized temperature measurements in:

• Immersion applications
• Air temperature measurements
• Insertion applications

The probe combines Class A PT100 measurement performance with a stainless-steel sensing body, four-wire connection and a 2 m cable for flexible installation.

Class A PT100 Temperature Measurement

The SE011 uses a PT100 platinum resistance thermometer with:

• Accuracy Class: Class A
• Accuracy at 0 °C: ±0.15 °C

This makes it suitable for applications where reliable general-purpose temperature measurement is required without moving to a higher-cost 1/10 DIN precision sensor.

Typical applications include:

• Laboratory temperature monitoring
• Equipment thermal testing
• Product development
• Environmental experiments
• Temperature data logging
• Industrial test setups
• Engineering validation
• Research and development

Wide −30 °C to +350 °C Temperature Range

Pico specifies the operating temperature range as:

• Minimum temperature: −30 °C
• Maximum temperature: +350 °C

The +350 °C upper limit makes the SE011 suitable for higher-temperature general-purpose measurements compared with several lower-temperature PT100 probes in Pico's accessory range.

Applications may include:

• Heated equipment
• Laboratory ovens
• Process equipment
• Temperature chambers
• Thermal experiments
• Air-temperature measurements
• Suitable liquid immersion measurements
• General engineering tests

The installation must remain appropriate for the probe materials and stated temperature range.

General-Purpose Immersion Measurement

Pico specifically lists immersion as one of the intended measurement applications for the SE011.

The stainless-steel probe can therefore be used for suitable liquid-temperature measurements where:

• The probe construction is chemically compatible with the medium
• The operating temperature remains within specification
• The connector and cable are kept appropriately positioned for the application

The complete probe assembly should always be installed according to the requirements of the measurement environment.

Air Temperature Measurement

The SE011 can also be used for general air-temperature measurements.

Typical uses include:

• Environmental chamber monitoring
• Laboratory ambient-temperature testing
• HVAC-related experiments
• Equipment enclosure measurements
• Research and educational applications

For air measurement, response time can depend on airflow, probe positioning and the thermal mass of the stainless-steel probe.

Insertion Temperature Measurement

Pico also specifies the SE011 for insertion applications.

The 150 mm probe length provides useful reach for suitable measurement points in:

• Test fixtures
• Equipment
• Laboratory apparatus
• Process setups
• Engineering prototypes

The SE011 should only be inserted into materials or locations that are suitable for its 6 mm stainless-steel probe construction.

150 mm Stainless-Steel Probe

The SE011 has a manufacturer-specified sensing probe size of:

• Length: 150 mm
• Diameter: 6 mm

The probe itself is manufactured from:

• Stainless steel

This provides a defined physical construction for general-purpose temperature measurements.

2 m PVC Cable

The probe includes a:

• 2 metre cable
• PVC cable material

The 2 m lead provides flexibility where the temperature measurement point is located away from the data logger.

This can be useful for:

• Environmental chambers
• Laboratory benches
• Equipment monitoring
• Test fixtures
• Process experiments
• R&D setups

Cable routing should take account of the temperature and environmental conditions around the cable itself.

Four-Wire PT100 Construction

The SE011 uses a:

• 4-wire connection

Four-wire measurement is particularly useful with resistance temperature detectors because a compatible measurement instrument can compensate for resistance introduced by the connecting leads.

This helps prevent lead resistance from being interpreted as additional PT100 sensor resistance.

The four-wire configuration is therefore well suited to precision PRT measurement instruments such as the Pico PT-104.

4-Pin Mini-DIN Connector

The SE011 is terminated with a:

• 4-pin mini-DIN connector

This provides direct connection to compatible Pico PRT measurement equipment.

The connector should not be described as “Tenth DIN.” A DIN sensor accuracy classification and a mini-DIN electrical connector are completely different specifications.

For the SE011:

• Accuracy class: Class A
• Connector: 4-pin mini-DIN

Recommended for Pico PT-104

Pico Technology currently lists the SE011 as a recommended sensor for the PT-104 High-Accuracy Temperature Data Logger.

The PT-104 provides four PRT measurement channels and supports standard PT100 and PT1000 sensors.

Using SE011 probes with the PT-104 allows engineers to create systems for:

• Multi-point temperature logging
• Long-duration thermal monitoring
• Laboratory experiments
• Product testing
• Research applications
• Environmental measurements
• Engineering validation

Multiple SE011 probes can be connected to available PT-104 input channels for simultaneous temperature monitoring.

Probe Accuracy and Complete System Accuracy

The published ±0.15 °C at 0 °C value refers to the accuracy specification of the SE011 PT100 probe.

The accuracy of the complete measurement system also depends on:

• Data logger accuracy
• Probe tolerance at the measured temperature
• Thermal contact
• Probe installation
• Environmental conditions
• Calibration status

For high-accuracy or traceable measurements, users should evaluate the complete probe-and-logger measurement chain.

No Handle Construction

Pico specifies:

• Handle: No

The stainless-steel probe connects directly to the 2 m cable rather than using a separate handheld probe body.

This makes the SE011 suitable for:

• Installed measurements
• Fixture-mounted measurements
• Laboratory setups
• Long-duration logging
• Semi-permanent monitoring applications

Typical Applications

The Pico SE011 is suitable for:

• General-purpose PT100 temperature measurement
• Temperature data logging
• Laboratory testing
• Immersion temperature measurement
• Air temperature monitoring
• Insertion measurements
• Environmental chamber testing
• Industrial equipment monitoring
• Electronics thermal testing
• Product development
• Engineering experiments
• Research and development
