8. Product Features
(1) Wide temperature range (100 to 1200 deg.C).
(2) High stability and low thermal gradient temperature source for calibration by
comparison.
(3) For use with wide range of sensors including large metal sheathed sizes to over 0.75
ins. diameter and facility to calibrate short sensors.
(4) Large immersion depths and low immersion depth errors.
(5) Probe immersions up to 22 ins. from one side.
(6) Probe immersion / calibration from both ends of furnace, doubles calibration volume
and throughput.
(7) Wide range of replaceable internal furnace tube diameters from fixed 3.15 in.
diameter (80 mm) to 2.55 / 0.5 in. (65 to 12.5 mm.) replaceable tube range.
(8) No moving parts / high reliability.
(9) Automatic 3 zone temperature control with individual adjustment of end zone power
over temperature range to compensate for losses and provide very low horizontal
temperature uniformity errors.
(10) Over-temperature “alarm cut-out’.
(11) Maximum power limit facility on all zones.
(12) Controlled ramp rate setting to provide temperature rise limit (deg.C. / min.).
(13) Three phase or single phase operation on supply lines.
(14) Input power circuit breaker with overload cut-out.
(15) Three pole isolation contactor to furnace heater zones.
(16) AUTOMATIC CALIBRATION- When furnace used with TTI7 or DVM / scanner and
TTI7 E software a fully automatic, large capacity, thermocouple calibration system
can be operated overnight using 10 to 24 TC channels with 3 or more sets of TC
channel data at 3 to 15 or more pre-set temperature points with automatic report
writing.
