Description
The Model 831
transmitters are the most durable,
accurate and cost-effective fixed range pressure
transmitter available. An all 316 stainless steel
transmitter, it is designed for years of stable performance
in even the toughest environmental and corrosive
media conditions. With its all-welded construction, this
transmitter is weatherproof and capable of a direct spray
with forces up to 200 psi without internal leakage. The
Model 831 (standard and low power) has FM and CSA
explosion-proof ratings. The 831D (differential pressure)
also carries the CSA explosion-proof rating. All Model
831s meet NACE standards for offshore applications. A
one year warranty is standard with every unit.
The small size and light weight of the Model 831 transmitter
eliminates the need for complicated mounting hardware
and mechanical supports, thereby substantially reducing
installation time. The in-line connection permits simple
fi eld wiring without the need for additional hardware,
adding to the speed and ease of installation.
The standard Model 831 and the Model 831D feature a
4 to 20 mA output standard with a 12 to 30 VDC power
supply. The Model 831 Low Power provides a three wire
Pressure Transmitters
