Amphenol HTP-65-A-D-754-J High temperature probe Datasheet

NTC Type HTP
Series
High Temperature
Probes
Applications
Description
• Temperature measurement and control
The NTC Type HTP Series high temperature probe
consists of a bead thermistor hermetically sealed
in the tip of a shock resistant glass rod. These units
are rugged and unaffected by severe environmental
exposures, including high density nuclear radiation.
• Temperature compensation
• Controlled temperature soldering stations
• Process oven control
A rugged high temperature bead thermistor
(Type HTBR55) is available on special order
Data
All NTC Type HTP Series high temperature probes
are aged at 842°F (450°C) for extended periods of
time. As such, they exhibit excellent stability for all
temperatures at or below 842°F (450°C). Intermittent
operations at temperatures up to 1112°F (600°C)
is permissible. When additional preconditioning
is specified, compliance with the performance
requirements of MIL-PRF-23648 can be guaranteed.

Typical model number
*The nominal standard value for the zero-power resistance at 257°F (125°C).
**The zero-power resistance at 77°F (25°C), expressed in Ω, is identified by a three digit code number. The first two digits represent
significant figures, and the last digit specifies the number of zeros to follow. Example: 0.06 in (1.5 mm) maximum diameter x 1/4 in
(6.35 mm) long glass probe with a zero-power resistance at 257°F (125°C) of 510 k and a tolerance of ±20% would be specified as
HTP60BD514M.
***Special tolerances are available on request . Consult the factory for special resistance tolerances, non-standard resistances and/or
non-standard temperatures.
