Applications
OMEGA’s PX103 Series
transmitters feature a rugged all
stainless steel case and a highreliability, low-noise 4 to 20 mA
output. They are designed for
use in critical applications in
wastewater management, chemical
manufacturing, water processing,
tank and level operations, and other
industrial applications in which
a non-plugging flush diaphragm
is needed.

[*] To order cable style insert “0” into model number; to order connector style insert “1”.
To order absolute pressure ranges, replace “G” in model number with “A” and add $70.
To order sealed gage pressure models, replace “G” in model number with “S” (no extra
charge). To order extra lead length [3 m (10') standard], add suffix “-(Length of cable in feet)”
and $2 for each foot beyond 10'.
Ordering Example: PX103U1-100GI, 100 psi gage pressure, connector style transducer, $555.
