Models 101, 102, & 103

Designed for a wide range of applications where a simple mounting scheme is required.
Model 101 is a Straight Sheath temperature sensor.
• Refer to Model 201 if welded fitting is required.
• Refer to 300 Series if spring loading is required.
Model 102 is a Copper Tip Sensitive temperature sensor.
• Refer to Model 303 or 304 if spring loading is required.
Model 103 is a Reduced Tip/Fast Response temperature
sensor.
• Refer to Model 203 if welded fitting is required.

Specifications:
1. Model
Base Model/Series Number.
2. A. Accuracy:

 

B. TCR:


C. Ice Point Resistance:

D. Response Time:

E. Tip Sensitivity:

Standard Class B (no code)
High Class A (code H)
Special Customer Specified (code S)
* Industry Standard is DIN Curve (code 01B), Platinum, 100 ohms @ 0°C. Conforms to IEC 751, DIN 60751.

Temperature Coefficient of Resistance is the temperature vs. resistance characteristics of a given metal
(Pt, Cu & Ni) used in manufacturing the RTD. Determines the curve of the RTD.

Ro - Resistance at 0°C (32°F)

Dependent on sheath diameter, the smaller the diameter - the faster the response. See RTD General Specs.

Model 102 Copper Tip, element is encapsulated in copper to increase sensitivity at tip of probe.

3. Construction:

Code A - 316SS tube and wire construction, thin film element (.00385055) TCR, Teflon insulated lead wire.

Code C - 316SS tube and wire construction, wire wound element, fiberglass insulated lead wire.

Code B & D - Inconel sheathed MgO construction, wire wound element, fiberglass insulated lead wire.

4. Lead Wires:
5. Sheath Diameter:
.250” (1/4”) is the industry standard. Code C/N for reduced tip design.
6. Sheath Length:
Entire stem length.
7. Lead Wire Length:
Length of wires beyond the sheath. Use Z000 if connector is installed directly on the end of sheath.
8. Lead Wire Protection:

Stainless Steel Overbraid or Stainless Steel Armor. Order length at 3”-6” shorter than lead wire length.
Example: Z024-X020

9. Connectors:
Optional male plug for sensor end. For mating jack add code “/J”.
10.Optional Fittings:
Sensor is not supplied with mounting hardware, specify optional fitting.
11.Water resistant:Increases moisture protection for humid environments.
