nnnnPRODUCT DESCRIPTION
nnnnBi-metal Temperature Indicator
nnnnThis is a rugged temperature indicator designed for general indus-
nnnntrial and process plant use and manufactured throughout in
nnnnstainless steel. It is provided with an external zero adjustment and
nnnncan be supplied with minimum or maximum value pointers. Where
nnnnprocess pressures are expected to be in excess of 3.5 Bar, it is
nnnnadvisable to use the BMI with a thermowell.

nnnnminimum of 60°C, maximum of 450°C.
nnnnThis instrument can also be supplied with the case in an any angle format
nnnnwhich allows the instrument dial to be selectively positioned for ease of
nnnnreading.
nnnnCompression glands in 316 stainless steel are available for mounting the
nnnnBMI to any process plant and they can be supplied with thread forms to
nnnnBSP or NPT formats.
nnnnWhen process pressures in excess of 3.5 Bar are expected it is advisable
nnnnto consider using the BMI in conjunction with a screwed or flanged ther-
nnnnmowell. These can be supplied as either fabricated (for process pressures
nnnnup to 10 bar) or solid drilled from hex bar stock. Please see Data Sheets
nnnn054 and 055.
