DESCRIPTION
The Model DCT Pressure
Transducer is designed for general industrial and commercial requirements
offering excellent performance over a wide range of applications. This new model
is based on proven micro-machined silicon technology providing high reliability,
long-term stability, and low cost relative to competing technologies.
This product is offered in a
variety of mounting and electrical output options, stainless steel or brass
construction, and numerous pressure ranges. It is fully digitally compensated
for the effects of pressure and temperature change and calibrated to produce
industry standard electrical outputs. The DCT accepts both unregulated and
regulated excitation voltages and provides output signals such as 1 to 5 VDC, 1
to 6 VDC, 4 to 20mA, 0.5 to 4.5 VDC ratiometric, or a 0 to 100mV output. The DCT
Transducer is offered in pressure ranges from 1 psi up to and including 500 psi,
and eventually will be offered in ranges as high as 5,000 psi.
The Model DCT is extremely
accurate, below 0.25% span over pressure and below 0.50% over a wide compensated
temperature range if required (<1.0% standard). The design incorporates a
stainless steel isolation diaphragm and 316 stainless steel construction for use
with most media types.
The DCT offers premium
performance and versatility of use for many applications, both for the general
industrial end user and original equipment manufacturers (OEM). It combines
precision along with the durability to operate under difficult environmental
conditions.
