FAQ's - 900 Analogue Input


1. What sensors can I use with the analogue input module?
You can use almost any analogue sensor such as thermocouples, strain gauges, flow meters etc. Typically the most common sensors used with this module are thermocouples. For help in selecting compatible sensors for your application please contact our technical sales department.

2. What else do I need anything else to complete a system?
The 900 analogue input module can be used as a standalone unit which would normally be permanently connected to a computer running data acquisition and control software. This module can be fitted with memory for complete standalone (no permanent computer connection) operation.
Alternatively used as part of a larger data acquisition, monitoring and/or control system with other 900 series modules. We are happy to supply complete fully integrated systems (including computers etc).

3. How do I install an analogue input module?
All 900 modules are designed to be easily installed. Normally the modules are wall mounted near the sensor/measurement area. All the documentation to fit the modules is included.
Alternatively we can supply installation as part of our package.

4. What specification of computer is required?
Any PC that can run Windows 98,ME,NT,2000 and XP. Screen resolution of at least 800 by 600. As a general guide if your PC is less than five years old it will almost certainly be compatible. We can supply a suitable computer as a complete system. Please contact us if you require more details. Top

5. Can I run the system on any Windows PC Software?
Windows operating systems 98,ME,NT,2000 and XP are all compatible.

6. Why use a 16bit AD converter?
Most of our competitors use a 12bit AD (analogue to digital) converter or even less. This will impact the instruments ability to resolve resolution over the sensors full input range. A 12 bit system can resolve only +-2048. Using a 16bit AD converter resolves +-32768. This means that we can get 0.1 resolution over the full range of inputs whilst competitors can only get this resolution over much smaller ranges.

7. How fast can I record data?
All 16 data channels are recorded in one second increments from one second to 12 hours and are user selectable. Just select the increment required and run.

8. How many readings can I take?
You can take an infinite number of readings. Usually all recorded data is transmitted to the computer (via RS485/232) and stored.

9. Can I use different sensors in each channel?
You can configure each of the 16 channels to any sensor calibration independently. i.e. you can have J-type thermocouple in channels 1 to 8, K-type in channel 9 to 14, Custom sensors in 15 and 16.
