INTRODUCTION

Read the whole of this book before commencing work with the unit.
The TC-9D Temperature Controller is designed as an alternative to the
energy regulator control provided in the laboratory fluidised baths. It is
supplied with a Chromel Alumel thermocouple which fits into the sheath
built into the fluidised bath.
The TC-9D provides the following features not provided by the energy
regulator:
1 Precise temperature setting.
2 Improved temperature stability.
Control is achieved by monitoring the signal from the thermocouple
sensor. By this means the controller will react directly to correct
temperature stability.
3 Stable temperature under varying loads.
With the energy regulator, the dial setting must be manually adjusted
to correct for changes in heat requirements due to a variation in bath
loading or ambient temperature. The TC-9D will automatically adjust
the heater output to take account of these varying conditions.
The TC-9D consists of a temperature controller mounted in a case with
solid state relay switching and is capable of handling up to 20 amps.
Connections to the fluidised bath and to the thermocouple are conveniently
made with sockets on the back of the instrument. In use, the TC-9D by-
passes completely the energy regulator control on the fluidised bath and
cycles all the heating elements on and off at the same time. The unit is
mounted on four rubber feet and provided with a three wire cord and
thermocouple.
