Standard Hastelloy
resistant material is compatible with most substances.
Reduces stock and minimizes purchase variations.
Easy Zero and Span Validation. Nonintrusive EZ CAL
option does not violate transmitter case. Allows zero and span
validation to previously defined pressure values without use of
the Type STT terminal. The EZ CAL option may be supplied at
delivery or added in the field, and can be used on any
Type PTSD pressure transmitter (except those with stainless
steel housings).

Measurements. Type PTSDDC pressure transmitter has
upper range limit of 30 kilopascals (120 inches of water). Pro-
vides optimum performance for the most common flow mea-
surement of 25 kilopascals (100 inches of water).
Turndown Ratios from 0.5:1 to 20:1. Turndown ratio range
from 0.5:1, where the calibrated span is actually twice the
upper range limit of the transmitter (from minus to plus the
upper range limit), to 20:1.
Enhanced Remote Communications. Communicates with
Type STT Smart Transmitter Terminal. Hand-held communi-
cation device uses high frequency AC signaling method known
as FSK (frequency shift keying). Functions in the high noise
environment found in many factories. The Type STT terminal
communicates with the transmitter anywhere there is access
to the signal wires within 1.6 kilometers (1.0 mile) of the trans-
mitter. Parallel connection does not disrupt the isolated analog
four to 20-milliampere process variable signal. The terminal is
also available in French and Spanish language versions.
Types STT04 terminals and later have the ability to communi-
®
cate with HART devices.
Low Range Differential Pressure Units. Type PTSDDA pres-
sure transmitters offer a range down to 0.1 kilopascals
(0.4 inches of water) full scale, providing increased accuracy at
low pressures.
Optional Two-Line,
Display. Displays output in percent and user-defined second-
ary engineering units, input in primary engineering units, cell
temperature, and transmitter ID tag. An analog meter is also
available for those applications where the transmitter operates
outside the temperature limits of the LCD. Both are easily
installed for convenient local indication.
Advanced Electronics Insures Reliability. The amplifier
assembly uses surface mount technology, designed to exceed
50 years MTBF (mean time between failure).
