Flex Armor Resistance Temperature Detector (RTD), Thermistor, Semi Conductor and Thermocouple

Temperature Sensor are available in 3 configurations;

Flex Armor Sensor
Flex Armor Sensor with Transition
Flex Armor Sensor with 2 Transitions

Flex Armor Temperature Sensor are commonly used in extruder and plastic processing and bearing industries.

The samples shown are 100 ohm RTD Temperature Sensor in a 4-wire, 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 .250". Transitions are 3/8" O.D.(Additional diameters are 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 to protect the lead wires.

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




Common types include; 100, 500 and 1000 ohm RTD temperature sensors,



2K, 3K, 4K, 5K, 10K, 30K, 50K & 100K Thermistor temperature sensors,



Types, T, J, E, K, N, R, S, B Thermocouple temperature sensor.



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.
