Bayonet RTD

Bayonet RTDs, Thermistors and Thermocouple temperature sensors are commonly used in extruder and plastic processing industries. These sensors provide accurate temperature control for the best plasticizing combination of plastic material, mold and design.

Bayonet RTD temperature sensors are available in 6 configurations;

Adjustable Immersion

• Bayonet on Flex Armor
• Bayonet on Flex Armor with transition
• Bayonet on Spring

Fixed Immersion

• Bayonet Straight
• Bayonet 45° Degree Bend
• Bayonet 90° Degree Bend

The 6 standard design’s are available to meet the requirements for space conservation while the cap and spring are provided to insure optimum contact with the process. With a pipe clamp adapter, the sensor can also be used to measure pipewall and bearing temperatures.

The samples shown are Dual Type J Thermocouple Temperature Sensors, Teflon insulated configuration. This provides an operating temperature range of -50 to 250oC. Fiberglass insulated wire is also available.

The outside diameter of the tip is 0.188″ (0.250 O.D. are also available)

The length of the tip, sheath, transition and lead wire are specified by the customer to suit the application. The lead wire can be supplied as bare wire, terminated with plugs, jacks, spade lugs, or junction boxes. For long cable runs, stainless steel overbraid or flex armor can be added.

Bayonet Thermocouple Specifications

• Thermocouple Type J, K, or N Standard Limits of Error ± 2.2°C or 0.75% (which ever is greater)
• Thermocouple Type T Standard Limits of Error ± 1.0°C or 0.75%; (which ever is greater)
• Thermocouple Type E Standard Limits of Error ± 1.7°C or 0.50% (which ever is greater)
• Thermocouple Type R or S Standard Limits of Error ± 1.5°C or 0.25% (which ever is greater)
• Thermocouple Type B Standard Limits of Error ± 0.50%
• Special Limits of Error also is available.

These temperature sensors configurations can be manufactured as RTD’s, Thermistors, Thermocouples.

Common Bayonet Types Include

• 100, 500 and 1000 ohm RTD’s
• 2K, 3K, 4K, 5K, 10K, 30K, 50K & 100K Thermistors
• Types, T, J, E, K, N, R, S, B Thermocouples.

We also manufacture customer specified temperature elements, including the Balco, Copper and Nickel temperature coefficients.

MIL-STD temperature curves are also rountinely manufactured by Thermometrics Corporation.
