Introduction
1.4.3
Electromagnetic compatibility (EMC)
The equipment is intended for use in a basic electromagnetic environment, characterised
by being supplied directly at low voltage from the public mains network.
All connections via the External alarm connection must use fully screened cable
no longer than 2 m.
Take care to avoid placing the BT37-02 in environments influenced by sources of
electromagnetic interference, such as large transformers for example.
1.5 About the equipment
1.5.1
Theory of operation
The basic principle of operation is illustrated in the diagram below.
Samples are placed in dishes in the left and right chambers which are heated to
maintain a constant temperature. Pre-mixed gas is supplied from a pressurised cylinder,
bubbled through water contained in the humidifier bottle, and then passed to the left and
right chambers. This results in the samples being maintained at a controlled temperature
and within a controlled atmosphere.
If the lids are opened and then shut again, gas is provided at an increased flow rate to
reduce the time taken to restore the chambers back to the required gas concentration.
The BT37-02 can be in one of three modes: Standby, Run and Bottle change.
