Platinum RTD Sensors With Industrial Protection Heads
PRTF-12, PRTF-14, PRTF-18, PRTF-19 Series:Platinum RTD Sensors With Industrial Protection Heads
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)
Fixed Length Probe Can be Used as a Direct Immersion Sensor with the Protection Head Isolating the Connections from the Outside Environment
Optional 4 to 20 mA Transmitters Can Be Conveniently Installed Into Some of These Protection Heads
Connection Head ion:
PRTF-12 = Cast Iron Screw Top Head with Terminal Board
PRTF-14 = Miniature Aluminum Screw Top Head with Terminal Board
PRTF-18 = Flip Top Cast Aluminum Head with Terminal Board
PRTF-19 = Sub-Miniature Aluminum Screw Cover Head with Terminal Board
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.

注釋:
* When installed in a thermowell, the thread engagement will equal the spring loading compression length.
Standard: Specify 1/8, 3/16 or 1/4 for probe diameter in inches. Standard probe lengths are 6, 9, 12, 18, and 24" but other lengths are available, specify length in the model number and price at the next longer standard length. Lengths over 24" can also provided, contact the Sales Department for availability and pricing.
Metric: Specify M30 for 3mm, M4.5 for 4.5mm or M60 for 6mm diameter. Standard lengths are 150mm, 225mm, 300mm, 450mm or 600mm but other lengths are available, specify length in model number and price at the next longer standard price. Lengths over 600mm can be provided, contact the Sales Department for availability and pricing.
