PX3005-DIFF
Pressure Transmitter with Display,
Rangeable Wet/Wet Differential
Product Details
The Omega differential PX3005-DIFF is a compact,
rangeable, pressure transmitter ideal for monitoring
pressures in process automation, hydraulic systems,
compressors, pumps, and in tank level applications where
consistent, reliable pressure measurement is essential.
The PX3005-DIFF utilizes a unique encapsulation
construction of a MEMs piezoresistive pressure sensor
coupled to an advanced microprocessing to provide
superior accuracy and performance.
The unique construction enables high line pressure
operations and superior protection from pressure
overloads. The rugged 316 stainless-steel enclosure is
IP67 rated making it suitable for wash down environments.
A 5-digit backlit LCD allows for a full precision
representation of process variable. Available in ranges
from 1 to 1,500 psi, the intelligent transmitter module
allows for configuration of the 4 to 20 mA signal, display of
input or output, and choice of 19 measurement units. The
output signal can be adjusted to re-arrange the transmitter
or “tare” unwanted fluid head preloads. Rangeability is
capable of adjusting zero and span are from -100 to 100%
FS URL (Upper Range Limit) with a minimum span of 30%
URL. This means a 15 psi transducer can have the zero
set between -15 to FS 15 psi. For example, zero could be
set for -15 psi and maximum 15 psi so the output would be
4 mA at -15 psi, midpoint 12 mA would be 0 psi and 20
mA would be 15 psi.
