Equipment
The TE-1500 is a complete system, consisting of:
„
TE-1500 Constant Temperature Bath
(Control Chassis & Bath Vessel Housing)
„
Assorted hoses, tubes, and connecting cables
Temperature selection
A selector dial on the front panel of the TE-1500 Control Chassis permits
convenient temperature selection at 10, 0, -5, -10, -15, -20, -25, and
-30°C for kinematic viscosity measurement. After the dial has been set,
the bath will equilibrate at or near the desired temperature. The operator
can fine-tune the temperature control to within 0.01°C of the desired
temperature using either the
FIXED
control knob (which permits preci-
sion control at the common temperatures listed on the Temperature Select
dial) or the
VARIABLE control knob (which allows for a wider range of
temperature adjustment to any setting b10°C and -30°C).
Bath components
Control Chassis
The Control Chassis for the TE-1500 contains electrical and pneumatic
components necessary for control of bath operations. The Control
Chassis front panel provides control options, including the bath power
and heater switches, temperature selection dial, and related fine-tuning
controls for regulating bath temperature.
Bath Vessel Housing
The Bath Vessel Housing for the TE-1500 rests on top of the lower
Control Chassis. It contains a rectangular aluminum bath vessel with a
four pane, custom-designed glass window.
The Bath Vessel Housing also contains the thermoelectric modules,
finned heat sinks, fans, and fluorescent lamps with ballasts. The rear
panel has two power connectors from the lower Control Chassis, two air
pump connectors from the Control Chassis, and the bath fluid Overflow
Jar along with integral pump and tubing connections for the TE-1500
bath fluid circulation system.
Power cables
Two large diameter power cables (AC and DC) with circular connectors
on their ends are provided to take power from the lower Control Chassis
up to the upper Bath Vessel Housing. Connectors have been designed to
attach only in the proper configuration.
Air hoses
Two small diameter silicone air hoses (tube assemblies) with twist/lock
pneumatic connectors on their ends are provided to supply and return
recirculated bath vapors between the upper Bath Vessel and the Control
Chassis. Connectors have been designed to attach only in the proper
configuration.
Overflow jar
One glass jar with lid is provided to catch the bath overflow liquid. This jar
is to be placed on the rear jar support and joined to the bath fluid control
system with the provided segments of small diameter silicone tubing. Fluid
from the jar may be recirculated to the TE-1500 bath vessel by depressing
the button marked
PUSH TO FILL
on the rear panel of the instrument.
