Description

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.
