Meters with on-site alarm function
Thread Content
For some small factories, the production method primarily involves manual operation by staff on site. Therefore, alarms for liquid level, temperature, and pressure in the control room are not very useful. Are there any liquid level, temperature, or pressure instruments that come equipped with on-site audible and visual alarms?
Install an audio-visual alarm on-site; it can be connected to the alarm output signal of the instrument. The instrument itself has alarm contacts, so it would be a shame not to use them.
There are many types of instruments with electrical contacts; simply connect those electrical contacts to a photonic panel or an audio-visual alarm
