This data sheet and installation manual
Before installation, commissioning and operation, make sure that the correct pressure gauge has been selected with regard to measuring range,
design and, based on the specific measuring conditions, the suitable medium in contact with the medium. Pressure gauges may only be installed
and serviced by trained specialist personnel authorized by the plant operator. Failure to observe the relevant regulations may result in serious
physical injury and/or damage to property.
