SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section describes the Type PTSDL Platinum Standard
Smart Level Transmitter. It also includes information about
special applications such as volume measurements and the
function generator. Refer to Figure
for an illustration of the
transmitter.
Type PTSDL Platinum Standard Smart Level Transmitters
measure levels of corrosive or noncorrosive fluids. The trans-
mitter can be configured to provide a polled digital process
variable signal (digital field bus mode) or a four to
20-milliampere process variable signal (analog mode). Uses for
the transmitter include process control applications in the
electric, gas, water, chemical, petroleum, pulp and paper, and
food industries.
FUNCTIONAL OPERATION
The Type PTSDL level transmitter has two major sections: a
cell and characterization board assembly, and an electronics
assembly. The Type STT Smart Transmitter Terminal commu-
nicates with the Type PTSDL level transmitter. The EZ CAL
option provides a way to validate the zero and span of the
transmitter without using the Type STT terminal.
