Rugged Design Offers a Variety of Protection Heads with 1/2 NPT Mounting Threads and a Screw-Type Terminal Block
Fixed Length Probe: 304 SST Sheath Connected to 304 SST Hex Fitting Spring Loaded: Improved Response Time and Vibration Resistance When Used in Thermowells*
Sensors Contain 100 Ohm Class “B” DIN Platinum Thin Film Elements
Standard 3-Wire Configurations with IEC60751/ASTM-E-1137 Color Codes (2- and 4-Wire Configurations also Available)
Fixed Length Operating Temperature: -50 to 500ºC ; Spring Loaded Temperature Range: -50 to 500°C (-50 to 260ºC at Head)

Optional 4 to 20 mA Transmitters Can Be Conveniently Installed Into The PRTF-12 (Cast Iron) and PRTF-18 (Flip Top Aluminum) Connection Heads. The PRTF-14 (Miniature Aluminum) and PRTF-19 (Sub-Miniature Aluminum) Heads Do Not Accommodate Transmitters Due To Their Small Size
Connection Head Selection: PRTF-12 = Cast Iron Screw Top Head with Terminal Board (Accepts A Variety of Optional Transmitters) PRTF-14 = Miniature Aluminum Screw Top Head with Terminal Board (Does NOT Accept A Transmitter) PRTF-18 = Flip Top Cast Aluminum Head with Terminal Board (Accepts A Variety of Optional Transmitters) PRTF-19 = Sub-Miniature Aluminum Screw Cover Head with Terminal Board (Does NOT Accept A Transmitter)
This rugged design offers a variety of protection heads with 1/2" NPT mounting threads and 304SS sheath. Note that the final length dimension is reduced by 1/2" so if used in a thermowell the sensor will not bottom and cause damage to the sensor. The standard probe uses a Style 2 (3-wire) lead configuration, but other configurations are available. All probes include a screw terminal block for easy connection of copper extension wire.
