PT100 probe, immersion, 1 m

The Pico SE014 PT100 Immersion Probe, 1 m is designed for engineers, laboratories, research teams and test environments that require reliable temperature measurement in suitable liquids.

Pico Technology describes the SE014 as a platinum resistance thermometer probe that can be partially immersed in liquids. Its combination of Class A accuracy, stainless-steel probe construction and four-wire measurement makes it suitable for general laboratory and engineering liquid-temperature measurements.

• Probe Length: 120 mm
• Probe Diameter: 3.3 mm
• Cable Length: 1 m coiled
• Probe Material: Stainless steel
• Cable Material: PVC
• Wiring: 4-wire
• Connector: 4-pin mini-DIN
• Handle: Yes

Class A PT100 Temperature Measurement

The SE014 uses a Class A PT100 sensing element with a manufacturer-specified accuracy of:

• ±0.15 °C at 0 °C

This makes it suitable for applications requiring reliable liquid-temperature data with tighter tolerance than a standard Class B PT100 probe.

Typical uses can include:

• Laboratory liquid-temperature measurement
• Research experiments
• Thermal testing
• Product-development testing
• Temperature data logging
• Engineering validation
• Controlled liquid-bath measurements
• Educational laboratory experiments

The overall accuracy of the complete measurement system will also depend on the connected data logger, installation and measurement conditions.

−75 °C to +250 °C Temperature Range

Pico specifies the SE014 measurement range as:

• Minimum temperature: −75 °C
• Maximum temperature: +250 °C

This broad range supports both low-temperature and elevated-temperature liquid measurements where the probe construction and liquid are suitable.

Possible applications include:

• Cooled liquid testing
• Heated liquid measurements
• Laboratory baths
• Temperature-controlled experiments
• Thermal cycling tests
• Engineering research
• Process-development experiments

The probe should always be used within its published temperature limits.

Designed for Partial Immersion in Liquids

The SE014 is specifically designed to be partially immersed in liquids.

This wording is important. The complete probe assembly should not automatically be described as fully submersible.

For appropriate immersion measurements:

• Position the stainless-steel sensing probe in the liquid
• Keep the handle and electrical connector appropriately positioned
• Avoid exposing the cable or connector to conditions outside their intended use
• Confirm that the stainless-steel probe is compatible with the liquid being measured

Pico does not publish a chemical-resistance table for SE014 on the current product page, so compatibility with aggressive or corrosive liquids should be assessed separately.

120 mm Stainless-Steel Immersion Probe

The actual stainless-steel probe dimensions are:

• Length: 120 mm
• Diameter: 3.3 mm

This is an important correction to the current RevineTech page.

The product does not have a 1 m stainless-steel immersion probe. The 1 m measurement refers to the cable.

The 120 mm sensing stem provides useful reach for suitable:

• Laboratory containers
• Liquid baths
• Test vessels
• Experimental setups
• Temperature-monitoring fixtures

Stainless-Steel Probe Construction

Pico specifies:

• Probe material: Stainless steel

The stainless-steel sensing stem is the part intended for appropriate partial immersion applications.

Rather than using generic claims such as “durable” or “industrial grade,” listing the exact stainless-steel construction gives engineers more useful product information.

1 m Coiled PVC Cable

The SE014 is supplied with:

• Cable length: 1 m
• Cable configuration: Coiled
• Cable material: PVC

The coiled cable provides flexible separation between the immersion point and the connected temperature logger while helping control excess cable around the test setup.

This configuration can be useful for:

• Laboratory benches
• Temperature baths
• Product-testing stations
• Research experiments
• Engineering development setups

Four-Wire PT100 Measurement

The SE014 uses a 4-wire PT100 connection.

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

This is particularly useful for PT100 temperature measurement because the sensor operates by measuring relatively small changes in platinum resistance.

Benefits of the four-wire arrangement include:

• Compensation for cable resistance
• Better measurement consistency
• Improved suitability for precision PRT logging
• Reliable use with compatible four-wire measurement equipment

4-Pin Mini-DIN Connector

The SE014 uses a:

• 4-pin mini-DIN connector

This provides direct connectivity with compatible Pico PRT temperature-measurement equipment such as the PT-104.

The connector should be described specifically as 4-pin mini-DIN rather than using a generic DIN description.

Integrated Handle

Pico specifies:

• Handle: Yes

The handle makes it easier to position and remove the probe during temporary immersion measurements and laboratory experiments.

It also helps distinguish the SE014 from fixed-installation probes that do not include a handle.

Recommended for Pico PT-104

Pico Technology currently lists the SE014 as a recommended probe for the PT-104 High-Accuracy Temperature Data Logger.

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

Using SE014 probes with the PT-104 can support:

• Multi-point liquid-temperature logging
• Laboratory bath monitoring
• Thermal experiments
• Research and development
• Product testing
• Long-duration temperature recording
• Engineering validation

Up to four SE014 probes can be connected directly to one PT-104 when four immersion measurement points are required.

Liquid Bath and Laboratory Testing

The SE014 can be useful where several liquid-temperature points must be monitored over time.

Potential applications include:

• Laboratory water baths
• Controlled liquid experiments
• Heating and cooling studies
• Product thermal testing
• Temperature stabilization experiments
• R&D measurements

When measurement accuracy is important, probe position, immersion depth, liquid circulation and thermal gradients should be kept consistent.

Probe Accuracy vs System Accuracy

The published ±0.15 °C at 0 °C specification applies to the SE014 probe itself.

The final measurement uncertainty may also depend on:

• Data logger accuracy
• Probe tolerance at the actual temperature
• Immersion depth
• Liquid temperature uniformity
• Thermal contact
• Calibration status
• Measurement environment

For higher-accuracy laboratory work, the performance of the complete probe-and-data-logger system should therefore be considered.

Typical Applications

The Pico SE014 is suitable for:

• Liquid-temperature measurement
• PT100 temperature data logging
• Laboratory bath monitoring
• Research experiments
• Product-development testing
• Thermal testing
• Heating and cooling experiments
• Engineering validation
• Multi-point temperature monitoring
• Educational laboratories
• R&D applications
• PT-104 temperature-logging systems
