The Series
1300 Smart Indicators/Transmitters are extremely
versatile digital process controls, ideal for use with Dwyer®
pressure, temperature and flow sensors. Microprocessor based,
all models are fully programmable and accept common thermocouple,
RTD, current or voltage inputs. An integral 20 VDC power
supply suitable for powering all Dwyer® 2-wire transmitters
is standard. Bright LED display automatically indicates
temperature range in °F (°C) based on selected thermocouple
or RTD input. For flow monitoring or control with Dwyer®
differential pressure transmitters, a preprogrammed SQRT
function may be selected to display actual engineering units
in CFM, GPM, etc. In addition, a user defined linearization
table is provided for non-linear functions, i.e., liquid
level indication in a side mounted cylindrical tank. Four
independent alarm status LED displays are fully programmable
to indicate process condition at a glance.
The Series 1300 is available with a variety
of output options including multiple alarm relays, analog
retransmission (current), bridge excitation (voltage) and
serial communications. Alarms are fully programmable: Hi,
low, deviation, deadband, time delay, manual or automatic
reset and NO or NC operation. Current retransmission may
be any part of the indicated range and the high value of
the retransmission range may be lower than the low value
(inversion). Consult factory for specifications and availability
of optional outputs not listed.
