Formaldehyde Monitor "if/B", Transducer, 0-10ppm
There is a configuration menu available to allow the user to choose output type, operation mode, select output tests, sampling range and also calibrate the Formaldemeter. The menu also allows for the incorporated voltage-less relay to be triggered at various concentrations so that external equipment can be controlled.
- Simple integration into existing sensor networks
- PLC control systems
- Stand-alone area monitoring
- Cleanrooms; Packing rooms & Workshops
- Single-point remote monitoring
Modes of Operation:
The if/B can be used in one of three sampling modes, depending on what best suits your needs. These are:
In this mode samples are only taken when a valid pulse is detected on the sample input line. If the instrument has not cleared sufficiently to sample at this point then the sample will be delayed - as soon as the instrument is ready then a sample will be taken. This is ideal for use with PLC or other controller based systems as the sampling rate is controlled by the input lines and the current status is available as logic levels on the output lines.
This mode does not require any external trigger for sampling. Samples are taken as often as possible by the Formaldemeter. The sampling duration would be dependent on sample concentration (higher concentration samples will take longer to clear and will delay the next sample). This mode is easy to setup and is ideal for applications where no controller based systems are available and the sampling frequency can vary.
This mode does not require an external trigger but unlike the previous continuous mode it uses an internal timer to trigger samples at a set frequency. This can be adjusted by the user between 1 and 60 minutes in increments of a single minute. However, the sampling frequency is not guaranteed as samples may be delayed if the Formaldmeter is not ready to sample at the designated time.
