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.
