Applications
Direct mounted system is required
High: >212°F Process Temperature
Low: < -40°F Process Temperature
Special Features
Specically designed heat-sink
Works in combination with diaphragm seal Dissipates temperatures up to 300°F in normal conditions
Standard Features
Cooling Element
Intended to protect the pressure instrument from high or low
process temperature. Air ow across heat exchanging ns
reduces or increases the temperature of the system ll uid to
protect the pressure measuring instrument.
The cooling element is recommended for process
temperatures above 212°F. It is direct mounted between thepressure instrument and the diaphragm seal. Silicone ll
is recommended. Effective temperature reductions of 300°F
depending upon ambient conditions. All stainless steel
construction is back-welded to stainless steel upper
housing or fange.
Capillary line
Stainless steel capillary with stainless steel armor provides
a connection between the pressure instrument and the dia-
phragm seal. It protects the pressure instrument from high or
low process temperatures and provides remote reading.
The capillary should be selected as short as possible, sincechanges in ambient temperature conditions may considerably
affect the accuracy and response time of the pressure instru-
ment. Standard length is ve feet; other lengths 2mm and
0.6mm are available upon request.
Installation on mechanical gauges normally requires a gauge
support and gauge adaptor or other surface mounting
provisions.

Diaphragm Seal Assembly with Capillary Line,
Gauge Support and Adaptor
Any level difference between pressure instrument and dia-
phragm seal will cause a pressure indication error. The level
difference can be compensated for during calibration of the
diaphragm seal assembly if level difference is known.
Minor corrections can be made on site by means of an
adjustable pointer or zero adjustment of the pressure instru-
ment.
Gauge Support and Adaptor
Provides wall mounting of pressure instrument by clamping to
gauge adaptor. Material: gauge support - aluminum or stainless
steel, gauge adaptor - stainless steel.
