Drum-chart recorder for pressure and temperature measurement
Field of application
- The drum-chart recorders are suitable for measurement of pressure or temperature whereas readings are recorded on graph paper by fibre pens
- The operating time of the drum per rotation can be 30 min, 45 min or 90 min as well
- as 24 h or 7 d. It is driven by mechanical spring winding or by battery supplied quartz controlled drive.
- Drum-chart recorders are used for measuring and recording pressure, eg at leak tests of tubes and other pipings for gas and water.
- The portable measuring instrument is particularly suitable for installation workings at building sites or when implementing gas or water connection in buildings
