Honeywell STR12D warranty Density, direct acting instrument configuration

34-ST-03-64 Page 16

Density or Interface* Calculate the minimum and maximum pressure differentials to be measured.

Pmin = (SGmin - SGf) x (d); minimum density, 4mA output

Pmax = (SGmax - SGf) x (d); maximum density, 20mA output

Where:

d = distance between the taps

SGmax = maximum Specific

Gravity

SGmin = minimum Specific

Gravity

SGf = Specific Gravity of capillary fill fluid (see page 11 for values)
