INSTRUCTION FOR THE INSTALLATION |
|
AND USE OF THE ASHCROFT BIMETAL THERMOMETER |
|
WITH EVERYANGLE CONNECTION |
|
This thermometer was designed to be
positioned to face the direction of easiest reading. |
| |
 |
POSITIONING THE STEM
Before installation, the stem should be set to the
desired angle as follows:
Figure 1: Loosen the 4 screws
labelled "A" and "B", until the harness revolves
freely.
Figure 2: While holding the case,
revolve the harness clockwise or counterclockwise, as indicated by
arrows, to place the harness in a position that will permit flexing
the stem in the desired direction with respect to the case. Then
lock the 2 screws "A". |
|
 |
Figure 3: Flex the stem to the
desired angle with respect to the face of the thermometer, then lock
the 2 screws "B".
INSTALLATION
The lower 2 inch of the stem is the sensitive
portion. Be sure this part of the stem is exposed to the temperature
to be measured.
Tighten the thermometer to the apparatus or into
the thermowell, using an open-end wrench applied to the hexagonal
head of the connection bushing. Do not tighten
by turning the thermometer case or the harness. |
|
 |
Thermometer case temperature limit, for
the normal dry case is a maximum of 200F. (For the liquid-filled
case the maximum is 150F. Liquid-filled thermometers are for
protection against sever vibrations.)
Thermowells: when used, coat the
thermometer with a heat conducting medium, such as a mixture of
graphite and glycerine, if fast response to temperature changes is
required.
If the temperature does not exceed 350F, vaseline
or any heavy lubricant may be subsituted for the glycerine and
graphite mixture. |
|
| If the operating temperature exceeds 350F
the glycerine graphite mixture may smoke at first, caused by the glycerine
vaporizing. The remaining dry graphite will act as the heat conducting
medium for temperatures up to 1000F. |
| CAUTION: Thermowells should be
used on all pressurized applications, to protect the thermometer from
corrosion or physical damage, and to facilitate removal of the thermometer
without disturbing the process. |
| MAINTENANCE: Aside from occasional
testing. little or no maintenance is required. |
| ADJUSTMENT: For Thermometers
fitted with an "External Adjustment" at the back of the case,
use a small wrench or screw driver or coin to turn the dial until the
pointer indicates the proper temperature. |
| CAUTION: Bimetal thermometers
operating below freezing must be hermetically sealed to prevent
condensation entering and freezing the the internals. |
