INTRODUCES SMART PRECISION PRESSURE TRANSDUCER
FEATURING ELECTROMAGNETIC INTERFERENCE IMMUNITY |
| |
| MINNEAPOLIS,
OCT. 5, 1998-Honeywell
today introduced a new model of the smart
Precision Pressure Transducer (PPT) which
offers an improved level of immunity to electromagnetic
interference (EMI). The new model features
a metal military-style bayonet connector and
a filter/voltage suppression circuit. These
enhancements provide a significant benefit
for avionics instruments, flight testing,
and other applications concerned with susceptibility
to EMI. |
| |
| The
PPT features 0.05 percent of full scale typical
accuracy including temperature effects from
-40 to 185 degrees Fahrenheit (-40 to 85 degrees
Centigrade). Integral digital signal compensation
greatly simplifies the task for the designer
requiring high accuracy over temperature.
Gauge, absolute, differential and vacuum ranges
cover full scales between 0 to 1 psi and 0
to 500 psi (0 to .07 bar and 0 to 34 bar).
Compound ranges cover full scales between
-1 to 1 psi and -500 to 500 psi (-.07 to .07
bar and -34 to 34 bar). |
| |
| The
PPT uses the industry-leading silicon sensor
technology developed for Honeywell's industrial
and avionics control systems, offering unmatched
reliability and stability. |
| |
| All
PPT models have both analog and serial digital
outputs (RS232 or RS485), and the 0 to 5 volt
output allows the transducer to easily retrofit
to analog systems. The serial output allows
the user to network up to 89 units on a single
bus, interface directly to a PC or other data
acquisition system, and address and customize
individual units. Customization can be implemented
using a simple set of commands from any PC
with a factory-supplied cable connecting the
PPT to the PC communications port. |
| |
| User-selectable
parameters include update rate, deadband,
analog voltage range and pressure measurement
units. The smart PPT can automatically increase
its update rate if a rapid change of pressure
is sensed, and it will set flags for out-of-range
pressure or temperature conditions. Straight
or right angle barbed fittings or threaded
Swagelokä fittings are available for pressure
connections. |
| |
| The
new PPT and the complete family of precision
pressure transducers are manufactured at Honeywell's
Solid State Electronics Center which is ISO9001
Certified. The PPT complies with CE Standards
EN50081-1-1992 and EN50082-1-1992, Electromagnetic
Compatibility - Generic Emissions and Immunity
Standards, Part 1: Residential, Commercial
and Light Industrial; and Electromagnetic
Compatibility Directive 89/336/EEC as amended
by 92/31 EEC and 93/68/EEC. |
