Series-TS-PROBES

Supported Applications

The Dwyer Series TS PROBES are digital temperature switch probes designed for use with the TS, TS2, TSS2, TSWB, TSW, TS3, TSX3, and 40M series controllers. These sensors provide direct measurement of process or ambient temperatures across a range of industrial applications requiring discrete switching based on thermal conditions.

Operating Conditions & Performance

The series supports three distinct sensor technologies with specific temperature envelopes:

• PTC and NTC sensors:-58 to 221°F (-50 to 105°C)
• J-type thermocouples:32 to 1400°F (0 to 760°C)
• K-type thermocouples:32 to 2300°F (0 to 1200°C)

The document does not specify accuracy, repeatability, hysteresis, resolution, or response time values for these probes. Electrical connections are provided via cable lengths of either 5 feet or 10 feet.

Probe Dimensions and Construction

• Diameter:1/4 in [6.35 mm] (Models TS-1, TS-2, TS-5, TS-6)
• Insertion Length:1-9/16 in [39.69 mm] (Models TS-1, TS-2, TS-5, TS-6)
• Stem Length:1 in [25.4 mm] (Models TS-5, TS-51)

Note: Overall length is not specified for all models.

Wetted Materials and Cap Options

• Brass:Standard cap material for PTC sensors (e.g., TS-1, TS-6)
• SS (Stainless Steel):Used with NTC and thermocouple models; also available as a brass thermowell accessory (TS-W) compatible with TS-1, TS-11, TS-2, and TS-21.
• PVC:Cap material for specific PTC configurations (e.g., TS-5).
• Polyamide resin coated brass:Available on select models such as the TS-6 series.

Configuration Options

The Series-TS-PROBES offers configurable options across sensor type, cap material, and cable length to accommodate different installation requirements. The model numbering convention follows the format TS-<MODEL>, with specific examples including TS-1, TS-2, TS-5, TS-7, TS-J, and TCS-K.

Sensor Types

• PTC (Positive Temperature Coefficient):Models include TS-1, TS-2, TS-5, TS-6 with corresponding 10-foot variants ending in '1' or 'T'. Cap materials vary by model.
• NTC (Negative Temperature Coefficient):Models such as TS-7 and TS-8 series offer options with no cap material specified or SS caps. Cable lengths include 5, 10, and 15 feet for specific variants like the TS-88T.
• J-type Thermocouple:Model TS-J features an SS sheath and a 4-foot cable length (1.21 m).
• K-type Thermocouple:Model TCS-K includes an SS sheath with a 4-foot cable length (1.21 m).

Cable Lengths

Probes are available in the following standard lengths as documented in the model chart:

• 5 ft (1.5 m):Standard for most PTC and NTC models.
• 10 ft (3 m):Available on extended variants such as TS-11, TS-21, TS-71, TS-81T, and TS-61.
• 4 ft (1.21 m):Specific to thermocouple models TS-J and TCS-K.
• 15 ft (4.5 m):Available on the TS-88T NTC model with SS cap.

Accessories

• A-TS-AP:1/4 DIN adaptor plate for panel mounting applications. Dimensions are 5/8 in [15.79 mm] x 4 in [101.60 mm] x 5/8 in [15.79 mm].
• TS-W:Brass thermowell with a 7/8 in [22.22 mm] HEX, 1/2 NPT process connection, and 25/32 in [19.81 mm] length.
• TS2-K:Configuration key for TS-2 series controllers (dimensions: 2-13/64 in [55.88 mm] x 1-27/64 in [36.07 mm]).

Key Product Differences

Variants within the Series-TS-PROBES are distinguished primarily by sensor technology, cap material composition, and cable length.

• Sensor Technology:The series differentiates between resistive sensors (PTC/NTC) for lower temperature ranges (-58 to 221°F / -50 to 105°C) and thermocouple elements (J-type, K-type) for higher temperatures up to 2300°F (1200°C).
• Cap Material:PTC models offer Brass, SS, PVC, or Polyamide resin coated brass caps. NTC models are available with no cap material specified or an SS cap.
• Cable Lengths:Variants ending in '1' (e.g., TS-21) typically denote a 10-foot cable length compared to the standard 5-foot version, while thermocouple models utilize shorter 4-foot cables. The TS-88T is an exception with a 15-foot cable.
