INTRODUCTION
The Indumart Loop-powered Indicating
Temperature Transmitter/Controller
(TST300) is a compact system which has
incorporated the latest digital technology to
provide accurate and reproducible
conversion of 2 or 3-wire RTD or
thermocouple signals to industry standard 4-
20 mA output and to indicate the process
temperature on its large 4-digit display.
Moreover, the TST300 with its 2 alarm
outputs can be used as an ON/OFF controller
to trigger external relays. The setpoint,
hysteresis, direction of the alarms and their
time delay can be programmed by the user.
High accuracy and drift-free linearization
coupled with digital filters are designed to
produce stable readings with good accuracy.
Configuration of the TST300 is easy. The
temperature transmitter is configured with the
aid of either a calibrator or an
RTD/Thermocouple simulator. The display
and contact parameters such as, setpoints,
hysteresis, direction and delay time, and
setting the span of the indicator to indicate the
desired engineering unit are programmed via
a two-key hidden keyboard.
The TST300 is waterproof (IP65), and when
coupled with thermocouple sensors, it
galvanically isolates the input signal from the
output. The unit can be mounted straight to
the RTD or thermocouple sensor, or be wall
mounted and connected to the temperature
probe via a wire. Optionally, the instrument
can be ordered with DIN rail mounting clamp.
