The PX831 is a durable, accurate,
fixed-range transmitter designed to
give years of stable performance in
even the toughest environmental
and media conditions. Its small size
and light weight eliminate the need
for complicated mounting hardware
and mechanical supports, thereby
reducing installation time
substantially. The in-line connection
permits simple field wiring without
additional hardware, contributing to
the speed and ease of installation.
