General Instructions

These instructions provide information for installation, process connection,

electrical connection, configuration, operation and maintenance of the 815DT

Smart Differential Pressure Transmitter. The 815DT consists of a field proven

stainless steel pressure transducer and a reliable switching output. The

housing features a stainless steel construction.

The 815DT is capable of powering long cable lengths. See Formula on page 3

for maximum loop resistance.

NOTE: If you suspect that an instrument is defective, contact the factory or the

SOR

representative in your area for a return authorization number (RMA).

Installation

Ensure that wiring conforms to all applicable local and national electrical codes and install

unit(s) according to relevant national and local safety codes.

Normally, line mounting provides adequate support for the instrument.

1st Step: Make the Process Connections (Hi & Lo)



The process connections can be threaded onto fittings within an adequately supported

process piping system. The Lo side may be vented to atmospheric pressure.



Use two open end wrenches when connecting the pressure ports to a process piping

system: One wrench to hold the hex flats on the pressure port, the other to tighten the

process pipe or tube fittings.



Process connection pipe or tubing may be rigid or flexible.
