This flexibility allows users to select the best sensor for their application.

Operating Temperature Range

The SMTS-TC is designed for moderate temperature surface measurement applications:

• Operating range: –50°F to 500°F (–45°C to 260°C)

This range makes it suitable for a wide variety of industrial, laboratory, and equipment monitoring applications.

Special Limits of Error Accuracy

The SMTS-TC is manufactured using Special Limits of Error (SLE) thermocouple materials, providing enhanced measurement accuracy:

• Accuracy: Greater of ±0.4% of reading or ±1.1°C

This level of accuracy ensures reliable data for critical measurement and testing applications.

Fast Response for Surface Measurements

The SMTS-TC provides responsive temperature measurement with a defined time constant:

• Response time: 6 seconds (time to reach 63.2% of a step change)

This allows the sensor to effectively track temperature changes in surface-mounted applications while maintaining stable readings.

Flexible Lead Wire and Insulation Options

The sensor includes flexible lead wire options to accommodate different environments and installation requirements:

• Wire type: 24 AWG stranded conductors

Available insulation options include:

• FEP (standard)

• PFA

• Fiberglass (rated to 900°F)

• High-temperature fiberglass (rated to 1200°F)

• Kapton

These options allow the sensor to be tailored for different temperature conditions and environmental requirements.

Grounded or Ungrounded Junction Options

The SMTS-TC is available with different junction configurations to suit specific application needs:

• Grounded junction: Faster response, suitable for many industrial applications

• Ungrounded junction: Electrical isolation for noise-sensitive environments

This flexibility allows users to optimize performance based on response time and electrical requirements.

IP64 Rated for Industrial Environments

The SMTS-TC is designed to withstand typical industrial conditions:

• Ingress protection rating: IP64

This rating provides protection against dust and splashing water, making the sensor suitable for a variety of environments.

Optional Connector Configurations

The SMTS-TC can be supplied with or without connectors, depending on application needs:

• No connector (bare leads)

• Mini thermocouple connectors

• Standard thermocouple connectors

This allows for flexible integration into existing systems and instrumentation.

Typical Applications

The SMTS-TC Miniature Surface Mount Thermocouple is ideal for:

• Surface temperature measurement on machinery

• Industrial process monitoring

• Laboratory and R&D testing

• Thermal performance analysis

• Equipment validation and diagnostics

Its compact size and secure mounting make it especially useful in confined spaces or applications requiring consistent surface contact.

Why Use a Threaded Surface Thermocouple?

Threaded surface thermocouples provide several advantages over adhesive or clamp-on sensors:

• More consistent thermal contact

• Improved measurement repeatability

• Secure mechanical attachment

• Reduced risk of sensor displacement

The SMTS-TC combines these benefits with a compact, durable design for reliable performance.
