To select the most suitable thermometer or temperature system for your application, or confirm your choice we would like information about the following areas:
- The process and the target
- The thermometer
- Signal processing requirements
- Signal presentation
THE QUESTIONS
Nobody likes a questionnaire. Particularly one that is as long and as detailed as this one. However, every question answered here helps
to ensure that the equipment we recommend/supply meets the needs of your application in every respect. Please help us to give you
complete satisfaction. Answer every question, where applicable, as fully as possible.
THE PROCESS
1 Brief description of your process.
2 Method of heating - e.g. oil-fired, high frequency induction furnace
3 Size, extent and position of any restrictions in relation to target surface and thermometer.
THE TARGET
1 Description of target - e.g. solid steel ingot, molten metal furnace roof.
2 Exact condition of surface - e.g. unoxidized, rough, covered with scale.
3 Target size available - e.g. 5mm diameter (or preferred target size if smaller).
4 Approximate temperature of target:
5 Distance from target to suitable thermometer location
6 Temperature and nature of immediate surroundings - e.g. workshop at normal ambient
temperature with tungsten filament, fluorescent lighting, interior wall of furnace chamber at 1000°C.
7 If the target is transparent what is the temperature and nature of the background - e.g. shiny
metal at 300°C, cold rough metal.
8 Surrounding atmosphere - e.g. air with combustion products, reducing, inert, vacuum.
THE THERMOMETER
1 Thermometer environment
How hot would the thermometer get without cooling? Specify temperature if known or 'hand
warm'/'too hot to touch'.
2 Specify any limitation of thermometer size
SIGNAL PROCESSING
1 Preferred output type
Other, please specify
2 Would you prefer the output to
Follow exactly the temperature of the target
Represent the hottest signals received from the target
To sample, and at periods determined by the process, hold the temperature
To produce an 'average' reading
Other, please specify
3 Do you require any of the following alarm functions:
High alarm only
Low alarm only
High and low alarm
4 When an alarm function is required what is the preferred response time of the alarm?
5 If you have any other signal processing requirements not covered by earlier questions please
describe them here.
SIGNAL PRESENTATION
1 What readout equipment is required
None
Digital indication
Analog indication
Recording
Control - state type e.g. ON/OFF
2 Any limitation on size of readout equipment.
