Fast-Response Air Temperature Measurement

The SE017 is specifically engineered for air-temperature measurements where temperature changes need to be detected promptly.

This makes it suitable for applications such as:

• Environmental chamber testing
• HVAC experiments
• Airflow temperature monitoring
• Laboratory climate measurements
• Electronics cooling studies
• Equipment enclosure testing
• Heating and ventilation research
• Product thermal validation
• Research and development

Pico identifies the probe as fast-response but does not publish a specific response-time value on the current product page. For this reason, the product should be described as a fast-response probe without claiming a specific number of seconds.

Class A PT100 Accuracy

The SE017 uses a Class A PT100 sensing element with manufacturer-specified accuracy of:

• ±0.15 °C at 0 °C

Class A accuracy provides tighter tolerance than a Class B PT100 sensor and makes the SE017 suitable for engineering, laboratory and environmental measurements requiring dependable temperature data.

Wide −75 °C to +250 °C Temperature Range

Pico specifies the temperature range as:

• Minimum: −75 °C
• Maximum: +250 °C

This broad range allows the probe to monitor both low and elevated air temperatures in suitable test environments.

Typical applications include:

• Cold-chamber testing
• Thermal cycling
• Heated-air measurements
• Environmental testing
• HVAC research
• Laboratory airflow measurements

The complete probe, cable and connector should always be used within their intended environmental conditions.

Designed Specifically for Air Measurement

The SE017 should be positioned primarily as an air-temperature probe, rather than as a general immersion or insertion sensor.

Pico offers separate PT100 probes for other measurement methods, including:

• SE014 immersion probe
• SE015 insertion probe
• SE011 general-purpose probe

Using the correct probe style helps ensure the sensor construction matches the physical measurement application.

120 mm Stainless-Steel Probe

The SE017 has a manufacturer-specified sensing probe with:

• Length: 120 mm
• Diameter: 3.3 mm
• Material: Stainless steel

The slim probe geometry makes it suitable for positioning within air streams, environmental chambers and other air-temperature measurement locations.

1 m Coiled PVC Cable

The SE017 includes a:

• 1 metre cable
• Coiled configuration
• PVC cable material

The coiled lead provides flexible positioning between the sensor and data logger while reducing excess loose cable when the full extension is not required.

This can be useful in:

• Environmental chambers
• HVAC test setups
• Laboratory benches
• Airflow experiments
• Product-development stations

Four-Wire PT100 Configuration

The probe uses a 4-wire connection.

Four-wire resistance measurement allows compatible instrumentation to compensate for resistance in the probe leads.

This is important for PT100 measurements because temperature is calculated from small resistance changes in the platinum sensing element. Lead resistance can otherwise introduce additional error.

The four-wire SE017 is therefore well matched to precision measurement instruments such as the Pico PT-104.

4-Pin Mini-DIN Connector

The SE017 is fitted with a:

• 4-pin mini-DIN connector

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

The physical connector specification should be kept separate from the sensor accuracy classification:

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

Integrated Handle

Pico specifies:

• Handle: Yes

The handle provides convenient positioning and repositioning of the probe during air-temperature measurements.

This can be particularly useful in temporary test setups and laboratory applications where measurements are taken at different locations.

Recommended for Pico PT-104

Pico Technology lists the SE017 as a recommended accessory for the PT-104 High-Accuracy Temperature Data Logger.

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

Using SE017 probes with the PT-104 can support:

• Multi-point air-temperature logging
• Environmental chamber characterization
• HVAC testing
• Product thermal evaluation
• Laboratory research
• Long-duration temperature recording
• Engineering validation

Up to four SE017 probes can be connected directly to one PT-104 for simultaneous four-point measurements.

Airflow and HVAC Testing

The fast-response air-probe design makes the SE017 particularly relevant to HVAC and airflow measurement applications.

Possible measurements include:

• Supply-air temperature
• Return-air temperature
• Heated-air testing
• Cooling-air measurements
• Equipment airflow studies
• Ventilation experiments
• Environmental chamber airflow monitoring

The actual sensor response depends on factors including airflow speed, temperature change, probe placement and surrounding thermal conditions.

Electronics Thermal Testing

The SE017 can also be used to monitor air temperature around electronic equipment.

Typical applications may include:

• Cooling fan evaluation
• Cabinet air-temperature testing
• Rack thermal monitoring
• Electronics enclosure studies
• Thermal management experiments
• Product qualification testing

For surface-temperature measurement, a dedicated surface sensor may be more appropriate because the SE017 is specifically designed for air.

Probe Accuracy vs Complete System Accuracy

The published ±0.15 °C at 0 °C value applies to the PT100 sensor probe.

Complete measurement-system accuracy also depends on:

• Data logger accuracy
• Sensor tolerance at the actual measurement temperature
• Probe positioning
• Air velocity
• Thermal gradients
• Environmental conditions
• Calibration status

For precision applications, the complete probe-and-data-logger measurement uncertainty should be considered.

Typical Applications

The Pico SE017 is suitable for:

• Air-temperature measurement
• HVAC testing
• Environmental chamber monitoring
• Airflow temperature testing
• Laboratory measurements
• Electronics cooling evaluation
• Equipment enclosure testing
• Product thermal validation
• Research and development
• Climate testing
• Engineering experiments
• Temperature data logging
• Educational laboratory testing
• PT-104 multi-channel temperature monitoring
