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.
