Differential pressure indicator (analog) – DA01
The DA01 from Fischer is a robust differential pressure meter, capable of withstanding very high maximum static pressures up to 400 bar. Optionally, the DA01 can be equipped with contacts.
To measure the pressure difference, the DA01 uses two flexible stainless steel membranes connected by a rigid connecting rod. Due to the high static pressure the DA01 must endure, the cavity between the membranes is filled with hydraulic fluid. The precision mechanism of the DA01 converts the linear movement of the connecting rod into a pointer reading. The flanges on the connecting rod protect the DA01 from excessive static pressure.
Advantages
- Long lifespan
- Corrosion-resistant
- Robust and highly wear-resistant mechanics
- Insensitive to dirt
- Safe for overpressure up to 250 bar
The DA01 is a versatile instrument, but its robust design and high quality make it particularly suitable for offshore applications and use in the chemical industry.
