Cambridge Scientific ID #: 22286Specifications:
Weight: 465 kg (1025 lb)
Height (overall): 120.7 cm (47.5 in.)
Width: 94.0 cm (37 in.)
Depth: 67.3 cm (26.5 in.)
Ventilation clearances: 5.1 cm (2 in.) sides; 15.2 cm (6 in.) rear
Maximum heat dissipation into the room: 1.0 kW (3400 Btu/hr)
Humidity restrictions: <95% (non-condensing)
Noise level measured 0.91 m (3 ft) in front of the Instrument: <57 dBa
Installation (overvoltage) category: II
Pollution degree: 2a
Revolution Counter: Displays accumulated total number of rotor revolutions in tens of thousands
Barrier Ring: 41-mm (1.63-in.) heat-treated steel alloy armor ring surrounded by a 12-mm (0.50-in.) steel vacuum chamber to provide full protection for the operator
Door: 17.5-mm (0.69-in.) high-strength structural steel
Vacuum: Diffusion pump in series with a mechanical pump typically reduces chamber pressure to below 5 microns (0.7 Pa)
Speed:
- Set speed: 1000 rpm to maximum speed in increments of 100 rpm
- Speed control: Actual rotor speed will be ±20 rpm of the set speed (above 1000 rpm)
- Speed display: Indicates rotor speed in increments of 10 rpm at speeds below 1000 rpm, and increments of 100 rpm at speed above 1000 rpm
Time:
- Set time: Up to 99 hours and 59 minutes; HOLD for runs of unspecified length
- Time display: Indicates time remaining in timed runs, time elapsed in HOLD runs, and estimated time remaining in ω2t runs
Temperature:
- Set temperature: 0 to 40°C in increments of 1°C
- Temperature control: ±0.5°C of set temperature
- Temperature display: Indicates rotor temperature in increments of 0.1°C
- Temperature stability: Within 0.3°C of set after equilibration
- Ambient temperature range: 15 to 40°C
ω2t Integrator:
- Set ω2t: Up to 9.99 × 1014 radians squared per second
- ω2t display: Shows accumulated centrifugal force to three significant digits (in exponential notation)
Acceleration: Selection from two profiles: maximum acceleration from 0 rpm to set speed, or slow acceleration from 0 to 500 rpm, followed by maximum acceleration to set speed
Deceleration: Selection from three profiles: full dynamic braking to 0 rpm, slow (full brake to 500 rpm followed by reduced braking to a gentle stop), or no brake
Operation: Standard, programmed, or delayed start; instrument memory can store up to nine programs
Key Switch: Used to select normal or zonal operation
